What kind of grease should I use lubricate the points behind the shoes?

High temperature disc brake grease or high temperature anti seive.

If you have never replaced drum brake shoes this will be a challenge ! If the shoes look good (reasonable thickness) I would just leave them alone.

It is not uncommon and it is much easier to replace the entire brake assembly, backing plate, pre-installed springs and retainers, new magnets, etc. You can buy left and right brake assemblies (lubed) for under $200 on etrailer.com.

I couldn't find a video specific to electric trailer brakes (most just replace the whole assembly), but this video is on drum brakes in general and I am jumping you to the point where they are applying the lube How to Replace Drum Brake Shoes


Why do you think your brake shoes need to be lubed ?

What makes you think you need to clean your TT brakes? Do you clean your TV brakes?
That being said, it always a good idea to inspect brake parts on a used vehicle or trailer. That way you know they are in good shape to travel.

For the traveling "I" do I inspect my brakes and bearing about every 5 to 7 years or so. About 10 years is the limit for the magnets on the trailer I own.

In short, there is no reason to clean brakes unless they are contaminated and that's a whole different issue.


This...Depending on the type, you may need to adjust the brakes periodically.

Do a brake check every time you hook up, also. Once you get out of the site on a straight away, manually activate the trailer brakes (low speed). It should give a good strong jerk and bring the rig to a stop. We also leave the flashers on once the ball is connected, so we can check the trailer lights are connected and operational while finishing up the getting ready to leave.


Thanks for the tips!

I have never serviced any vehicle brakes to just "clean them".. [emoticon]

Drum brakes do get some brake dust in them over the years, but will usually wear out before you need to just clean them.

For TT brakes specifically and if they are drum type brakes there will be an adjuster lever on them and in the newer ones, they will auto adjust.

I've had both and the only reason I pulled the drum off was to check the wheel bearings and then check the condition of the brakes and adjust accordingly.

With my new Rockwood, it's supposed to self adjusting brakes, but I plan on pulling the drums on them and looking for myself after a season and a half of towing it.

Just wanna check things out on it and see the bearings and how this so called auto adjusting thing works on it. Figure it's similar to auto drum brakes that auto adjust when you back up or use the brakes in general, in the case of a TT..

Anyway, going to pull them before the camping season and look for myself.

Good luck, Mitch

Honestly, on mine, I do nothing unless I notice an issue.



Right, about an issue... During the last summer, when I was coming to full stop (probably around 10-15 mph) the truck and the trailer were swinging (going back and forth for a few seconds). It happened probably 5-6 times during the whole season. I though the brake controller output was too high, tried to lower it, but it didn't help.

Any chance someone had the same issue or knows what might be wrong?

I don't. I'm planning to do a service (grease, inspect brakes) in a few weeks, would like to see what I might need for this service.

With ez lube system, I don't need to grease the bearings during the reassembling (after the inspection), right?
I can grease it once I'm done, with grease gun, correct?

I will never use the EZ-Lube grease zerk because of the excessive amount of grease in the hub and the very likely chance of grease getting on the brakes. Thoroughly clean the bearings and inspect them, then grease by hand. I use the grease gun to flush the old grease out of the hole in the spindle while it is apart, then never use it again. Do it right by hand and don't depend on gimmicks like EZ-Lube.

When you say, truck and trailer swinging back and forth, I'm assuming you mean in a TV and TT straight in line swinging ahead in the truck, correct?

Did you have a half or 3/4 tank of water in any of the tanks? Fresh, grey or black? Of some in all 3?

I'm assuming you are using a weight distribution hitch?

Do you feel any lose play in the tow ball or truck receiver connection?

About how fast was the deceleration? A hard stop, a medium stop or a long light stop? I know this is subjective, but trying to get more info on your setup to know what may have created that reaction.

If I understood the way the truck was wiggling back and forth, I know the feeling, on a tractor and implement filled with water. The water does not stop solid, it sloshes back and forth in line with the tractor and implement. The faster/harder the stop, the worse it was. I have not had this happen on the camper, but large water tanks on a camper filled with water, could do this.

As to the EZ lube setup, I am not a fan of them on a brake axle setup. They have their place on a boat trailer. On a TT setup, sooner or later, the grease can/will blow by the seal into the brakes. The hotter the summer day, on a long tow, the worse it can be. They do make oil or grease seals to hold thousands of pounds of pressure, but they are not what is in a conventional trailer axle.

Hope this helps

YouTube has a number of “how to” TT brake videos. Start there IMO.


Here's one to get started.

One on Bearing Repack too

You absolutely must grease the bearings before assembling them. Never reassemble a wheel up dry.

Best write-up yet on EZ-Lube. That's my technique as well.
Here's a video on EZ-Lube hubs which pretty much sums up what Lynnmor describes above
