RE: Brake Pads

Forgot...going too high in performance will have some liabilities you will need to consider and manage I went with Performance Friction carbon when they first came out. He's a buddy of John at Praise Dyno Brake. Both used to work at, think IIRC, Holly or some such Anyway, they were GREAT when hot, but when cold...slide right through a cross walk in front of an elementary school. Lucky very early and if later...it might have been filled with kids Friction material *ALL* have a working temp range. The higher performance they are, the higher the lower end of their working temp range. Those good at the lower temp range will have a lower high end range. Some mix and match to try and get a wider temp range, but a compromise at best on the ones I've tested

RE: Brake Pads

snip... Out of curiosity, What point are you supposed replace pads? I think I'm getting down there but not sure when to replace. Any surprises putting them on? First, which pads is so dependent on how you drive, where you drive and what you tow/haul. Choices range from freebies that comes with rebuild calipers to performance to pure racing. I'm in the performance to racing with racing prototypes from buddy I test all the time On that, recommend folks test their ABS about once a month. Find a gravel or loosey goosey pavement with no traffic and nail them. Wakes up most ABS systems Purchase based on cost, generally. The more expensive generally are better than the cheaper ones. Your decision based on how you drive and maintain your vehicles. Mine normally list for over $100 bucks but get discounts (AAA at NAPA, and got to know lots of the folks at various supply shops and buddies who are always formulating stuff) Friction material's thermal characteristics has them out gas when at a certain temp range. That will float them off the cast iron and is what 'fade' mainly is Their ability to reject heat to the backing plate and then to the other thermal pathways to reject is one key If the friction material is too thin, it will NOT have enough thermal inertia to both radiate and transfer heat to the backing plate That will then have the friction material heat up quickly and out gas A bad thing Most of today's pads have "squealers' on them to make a squealing noise when they touch the rotor. Most are only on one side of the caliper and is the piston side, which wears faster than the anvil side. Most has the piston side on the inside and the anvil on the outside and that is mainly for clearance for the wheels (the stuff like hose, banjo, bleeder, piston cylinder, etc) I normally change mine before the squealers contact and depends on which vehicle. Just changed the mini van and still had a bit to go before the squealer touches. Noticed that braking was lessened and with the level of performance pads...made a ruckus...like gravel on the rotors once they came up to temp For the mini van I buy from NAPA and found a new performance level I like a lot for 'cars'. Nissin is the brand For the Silverado still have Praise Dyno Brake front and rear. Great stuff out of Texas and GREAT folks (love that family run business) Suburban has buddies prototype and will have to give them back soon for him to check out in his lab The Sub's rear are Praise Dyno Brake shoes and think around +100K miles of SEVERE duty on them On any surprises...depends, but most today are very similar in architecture So they pretty much all go through the same sequence Key is making sure the sliders are working FREELY. I have my own setup to inject high temp disc brake grease (loaded with Moly). I always replace the slider boot...if they are available. I also bleed the lines each time I change the pads. Use the 'C' clamp method and can do it alone without the need for a helper

RE: Tow haul button

Thank you!!!! I've never worked on any of the NV manual trannies and wonderful to hear that they are that stout ! Manual or automatic page 9 JRMora wrote: BenK wrote: A manual weighs less Apparemtly you've never picked up a NV5600. It's a cast iron son of a B. Literally. It's got to be one of the heaviest six speeds out there. I hope one never falls on my foot! Juan The NV5600 is 360lbs. IIRC the Allison in the GM trucks is the largest auto in a light truck and it only weighs 330. The 4L60e/4l80e in the GM trucks without the Allison is under 300.

RE: Tow haul button

All of this is why I still prefer manuals...I'm in control and don't have to second guess or stand on my head...tapping my belly button to kinda sorta get the 'automatic' to do what *I* want it to do... But since the automatic herd out numbers those who prefer manuals...the OEMs no longer offer manual trannies on the vehicle I want to buy (order new or used) 'Tow/Haul' has only one definition in automotive dictionaries. Why make it so complicated? If MPG is so high on your list of 'have to have', then don't use that button. As it will or might get higher MPG, but the increased stresses on the drive train (engine all the way to the tires) will wear it out sooner. Not have it fail instantly, but sooner than if you did use that button. So decide to save a few bucks on fuel and risk the system and/or component which has the two most expensive parts in any TV...the engine and automatic (tens of thousands of bucks) Folks who trade/sell in a few years will 'most likely' dodge that failure and pass that to the next owner...

RE: 2004 4l80e hot trans on hills

On GM full sized +8.6K GVWR will have hydro-booster instead of vacuum booster for power brakes Uses the steering pump as HIGH PSI source and is plumbed to it's own external cooler on the left side of all other external coolers This picture is of my front end while at the shop fixing the front right fender and busted right steering knuckle from smacking a LandRover which jumped a stop sign (I was through traffic, so no stop sign for me) http://img.photobucket.com/albums/v77/bentoy/01240019.jpg width=640 http://img.photobucket.com/albums/v77/bentoy/01240007.jpg width=640 Tough to see, but it is on the drivers side and is vertical tube fin Mine also gets VERY hot off roading, but not like Burbman in the sand. I move boulders out of the way with the wheels...nudge up to them with the tire just to one side and turn the steering wheel Burbman, check your front end joints...and stay away from MOOG. Junk now that they sold out and the new owner has them made in China I've go NAPA HD in there now and waiting to see how they perform... Back on topic...I don't see how the power steering and hydro-booster system is tied in with the engine coolant system. Even the ATF in tank is isolated and would have to spring a leak (it is inside the cold tank of the main radiator) The power steering/hydro-booster system is completely isolated from both the engine coolant system and ATF system

RE: New Chevy/GMC pickup headlights

PS...my highs are 'bare bulb' and lights up the whole area from the ground up to the trees and to both sides 'Bare bulb' meaning both no shield covering the bulb and the bulb itself does NOT have it dipped into 'paint' to cover the element PPS...when oncoming either has their highs on and/or mis-adjusted...I'll flash them my highs.

RE: New Chevy/GMC pickup headlights

About time DOT came out of the dark ages (pun intended) I've been running E-Code headlamps for decades, but the new non-standard molded head lamps makes it tough to find E-Code head lamps. Planned and just haven't yet, to mount E-Code head lamps on a bumper guard. Both low's (H4 or if can find them, H3 low and H1 high) and highs (H1 100 rally) Two low/high rectangular and two high rectangular (maybe 4) Typical North American DOT rated beam pattern. Notice the glare into oncoming eyeballs http://img.photobucket.com/albums/v716/hondaman94/DSC01746.jpg width=600 E-Code with a flat cut off and the typical wing to light road signs/pedestrians/etc. Notice no glare to on coming eyeballs http://img.photobucket.com/albums/v716/hondaman94/S5000010.jpg width=600 This is a 'Z' beam pattern, as some folks complain about that 'wing' wedge http://img.photobucket.com/albums/v716/hondaman94/bbbbbml1.jpg width=600 This is one without the 'wing' http://img.photobucket.com/albums/v716/hondaman94/Cutoff1.jpg width=600 Best automotive lighting guy is Daniel Stern and his web site clicky: Daniel Stern Lighting His bulb spec page and why I love H1's and any 'rally' QH bulbs in 'glass' lenses (lead crystal as in table stuff, not silicon glass) Daniel Stern Lighting, bulb spec Some, to date, North American Headlamps have 'tried' to copy the sharp cutoff, but since plastic lens and El Cheap metrics, still has glare above where E-Code would have a sharp cutoff PS...careful where and who you buy from. Daniel Stern's stuff is the 'good' stuff...I have no affiliation with Daniel Stern, other than am very pleased with both his info and products

RE: Jumping off the Diesel Bandwagon - UPDATED

Ditto that back around 2000 when noodling either stuffing in a diesel into my Sub or getting a new TV BUT...I also considered the SMOG freight train coming down the tracks and deja vu of the 1980's SMOG on gassers... Plus I do NOT purchase any of my vehicles for resale. Since I keep them forever or till the wheels fall off and won't/can't fix them anymore Not saying don't get diesel...just IMHO for "ME" gassers make more sense

RE: 2004 4l80e hot trans on hills

Lifted? Over sized tires? Both reduce ratings and efficiency Automatics are hydro fluid coupled and has a 10%-15% or more slippage. Inherent in how they work. Why they invented the TC lockup to remove that slippage, but lost is the torque multiplication of hydro fluid couple that a TC's design enjoys That slippage is why ATF gets hot, mainly. There are also losses in the planetary's and bearing, but minor in comparison to the hydraulic slippage (shearing of fluid) Also, what are your weights and speeds/terrain/etc you drive? Heavier poses more stress on the TV & components...therefore more heat generated by the TC.

RE: Tire question

IMHO... Just because a tire or any component has a higher speed limit...does it mean you 'have' to go that fast... High end street racing tires may have a 200MPH speed rating, but they also perform well at 55 MPH... If there is any question on anything and there is a better choice or option albeit a bit higher in price has me go to the better/best one with little to no decision time required All wheels sold in the USA has a DOT mandate to have their spec some where on the wheel. Ditto tires Most are on either the interior (hidden by the tire) or back side Some are painted/screened on, others stamped into the metal or cast in Just like sizing things just barely or slightly below the actual usage will have a constant worry. I'd just get the best can afford and biggest can afford...but know that I'm in the vast minority here on this forum...

RE: Only 2 of the 9 SUV's passed the safety crash tests

Boils down to personal choice...some more informed than others... ;) As long as they allow EVERY one out on the same playing field...there will always be or potentially large deferentials... Think of any NFL game that allows anyone...everyone in the stands to mozy out on the field among the +300 lb players who are wearing armor. That *IS* about what we have been talking about...maybe having some skin in the game vs in-animate objects might help some to see what we have been talking about. Sure the 150 lb guy will be able to out run and out maneuver a +300 lb tackle...but all it takes is to not be able to *ONE* time... I'll not ride in the Fiat 500, but do occasionally ride with buddy who drives a Mini. Maybe the 500 in pure city traffic with no more than 35MPH, but surly not out on the freeway Know am at a disadvantage in my 2 seater (when I've found time and $$$ to restore it). As it is about 2,400 lbs with me in it. It has an about <7:1 weight to power ratio, racing brakes, etc...so can and does get out of the way of many potential accidents...by definition...an accident is an accident and hope I'll survive Why my two kids first ride was the Silverado listed in my sig. Eldest was rear ended while at a stop light. Destroyed the full sized sedan which rear ended her and also destroyed the full sized sedan in front of her Our Silverado did need a new rear, passenger box side and frame straightened She got a bump on the back side of her head and luck she had her hair in a pony tail There is not one body panel that hasn't been dinged/dented/hit/etc and proof of my decision for a full sized pickup as their first ride Helps that it has 33/12.5R15LT load range C tires, which are about 6 inches taller than the OEM's 27" dia 'P' class tires. So all of the accidents has had our Silverado ride up on them. For those who less informed...then the Consumer Reports/R&T/Car-n-Driver/etc the best source for their decisions PS...Turtle has way more patience than I do...cuz am bald from both the green/red/purple/blue hair teen years of my girls...and pulling them out on these forums... :C

RE: Re-Wiring the brakes.

It's only going to be as good as the weakest link in this food-chain and that will be the connector between the TV & trailer I'd get a NEMA 4 junction box with a 30amp minimum terminal block mounted on the inside. That TB needs to have 'U' jumpers to tie several terminals to become the hot and ground...plus the control lines for the rest of the trailer Then from that point you can decide spider (wagon wheel with it the hub and the points the spokes) or one big lead 'back' there Make sure to use ring lugs and NOT spade lugs. If you don't have lots of experience crimping lugs...practice, practice... Suggest buying your connectors in large, contractor quantities. Especially if you are going to be working on your own stuff. I also buy'm on sale so the per connector cost many times is less than half of list. Here is one of my electrical setups when doing the harness for my Suburban http://img.photobucket.com/albums/v77/bentoy/Towing/CIMG0029Ringlug.jpg I no longer own a trailer, but borrow often. Some allow me to update their's when I've decided going to borrow often. I use a #10 AWG with a ring lug to their trailer end of the connector Then run one #10 AWG wire 'back' there and then split it to both sides. Since not mine and they won't pay for the install...just a 'thank you' I don't put a NEMA 4 box back there. Just water proof the splice

RE: Only 2 of the 9 SUV's passed the safety crash tests

just buzzed in for lunch and checking this thread and noticed that my analogy might be lost on many...so this video to show what meant... Notice that when he lifts and drops one ball...only one ball is moved on the other end. Then when he drops two balls, only two balls are moved, etc The kinetic energy is transferred to the mass of balls and only enough to move whatever is transmitted from the same number of balls will be moved Of course there is no crumple zone stuff, but direct and is the basics of this thread...crash transfer of kinetic energy and how that is mitigated via crash crumple zones Newton's Cradle with bowling balls This one guy talks a bit deeper into the laws of physics of this topic Newton's Cradle explained

RE: Shifting into neutral

Illegal in Calif V C Section 21710 Coasting Prohibited Coasting Prohibited 21710. The driver of a motor vehicle when traveling on down grade upon any highway shall not coast with the gears of such vehicle in neutral. Also, in automatics that do NOT have a rear pump...coasting in neutral will have little to no lube pumped to the bearings inside the automatic and will ruin them in a hurry

RE: Only 2 of the 9 SUV's passed the safety crash tests

Forgot to touch on race cars and how they manage deceleration of the body without crumple zones GMCSMOKE is smack on...their crumple zones are with the collapse of parts and the tearing off of parts. Plastic parts (carbon fiber) explode after they consume enough energy Also designed sequencing of failure Meaning that the inner parts might have grade 8 fasteners and as you move farther away, grade 5's and/or smaller margins to have them fail 'first'

RE: Only 2 of the 9 SUV's passed the safety crash tests

Legendary Dale Earnhardt's death caused NASCAR to make changes to rules that dictate how to decelerate the body and in his case...the head His impact was NOT very hard, nor going very fast... It can be built like a tank and the vehicle survive, but occupants might not Again, key is the rate of deceleration, or rate of change, for the person (all parts) Just noodle any of the Sci-Fi movies where they jump to light speed in a flash... Unless they have some mechanism to keep everyone inside the vessel from flying to the back of the vessel to become ink spots 'back there'...won't work. No difference between that analogy and a crash...just different directions of 'the rate of change' in speed The rate of change for the body and most importantly the head...the brain from smacking the inside of the skull, is the key to managing a crash Suspend a bowling ball and soccer ball on a length of rope anchored on the same eye bolt in the ceiling The length of rope is sized to have both balls meet in their equator Lift both up the same angle away from vertical to be horizontal Let go of both at the same time When they meet/crash into each other at the bottom of their swing arc...which on will bounce farther away from the impact at vertical? The one with less mass, therefore less kinetic energy will bounce farther away from the contact point.

RE: Only 2 of the 9 SUV's passed the safety crash tests

The whole point of crash crumple zones is to decelerate the body(s) inside the passenger compartment to the point that they will survive. Above a certain point in speed/energy...they will die or maimed severely no matter Seat belts hold the body but there is a sudden impact when the slack is taken up. The Air bags then decelerate the head further All the while the sheetmetal is folding up like an accordion. Anyone ever see the crumpled sheetmetal ? Here is what a typical frame rail folded up along the designed in stress raisers http://www.toyota-4runner.org/attachments/3rd-gen-t4rs/80730-bumper-talk-arb-crumple-zone.jpg width=600 Similar for a monocoque/unibody, but no frame per say...just the front engine stub rails and body sheetmetal will fold up like this (inside the outer sheetmetal...fender/etc) Notice that if the other vehicle's bumper is either above or beneath this ones bumper...that it will potentially slide over/under this area Here is a monocoque/unibody and it's crumple zone http://upload.wikimedia.org/wikipedia/commons/6/6c/Lotus_Evora_front_crash_test.jpg width=600 Ratsf..link doesn't work, so here is the direct address: http://upload.wikimedia.org/wikipedia/commons/6/6c/Lotus_Evora_front_crash_test.jpg Again, notice that the bumper height important for the stress raisers to do their job On that, notice in this picture of how they test...that they do NOT have a bumper to bumper impact, but to a wall. http://upload.wikimedia.org/wikipedia/commons/4/4a/FAE_visualization.jpg width=600 another rats...here is the link: http://upload.wikimedia.org/wikipedia/commons/4/4a/FAE_visualization.jpg That is how the article's rating is based on...hitting corner of a wall NOT bumper to bumper. Their side impact is more real world, as they do have a sled smack (T-Bone) it from the side...but the sled's bumper height also very important As for which is better...smaller or bigger...depends on lots of factors First that the kinetic energy is dependent on both the mass and speed of each vehicle As they both crumple...they are consuming kinetic energy. The rates of consumption dependent on how they are crumpling...or not Once their crumple distance is consumed to now have the solid portion of their passenger compartment become involved...the one with more kinetic energy will impart that onto the event. That will have the one with less kinetic energy lose ground and move backwards...meaning the people in the one moving backwards will then have that kinetic energy imparted on their bodies via: seat belt, air bag and anything else that strikes them Much more going on, but that is the basics of it all...

You folks need to understand how corporate America works Engineers do NOT have that level of authority Not even middle managers Only high level exec's have that kind of signature authority. They may assign their signature authority to middle mangers, but then they are also accountable for those assigned signatures Signature authority is based on bottom line dollars affected/effected This decision was worth hundreds of millions of bucks...so no middle level manager has that kind of signature authority Agree...these engineers are their goats...
