The Jayco 24 RBS I purchased this spring I noticed the back 2 brake drums where super hot and the front 2 drums where not hot at all after doing a trip. Had to wait 1 month for my scheduled service today. Tech said rear brakes were almost frozen, cleaned up brakes and calibrated. After hooking up trailer at the service center which was on a slight down grade I let the truck & trailer roll slowly in neutral. I then put on the manual break to full gain... Nothing... I then got the tech we repeated the test with him pulling the brake away pin.. still nothing... So tomorrow the shop foremen is going to work on the brakes.

So my question is on my past 2 trailers when doing a similar test when I activated the brakes in full manual gain the trailer brakes always locked up or almost locked up. I a missing anything? help.

Also had the bearings repacked.

I don,t read where the shop tested your brakes before turning the rig over to you? need new shop. you could have pulled down the high way with no brakes.

I do my own brake maintenance because I know that I do it correctly. Some shops hire anyone that thinks he knows what a wrench is.

I believe you are missing nothing. Consider getting another shop to verify your TT brakes were fixed correctly.

Did they work before, aside from the hot/cold thing?

Could be several things, fortunately trailer drum brakes are one of the simplest mechanical assemblies on a "vehicle."

First, if it appears that none of the brakes are working at all, then greater chance it's the power supply, wire, trailer plug, even brake controller, somewhere upstream of the individual brakes.
Other things.
Could be all are mis adjusted very loose and not enough travel to even engage.
Could be bad magnets, shorted wire to a brake.

There are many published diagnostic procedures, if you're actually trying to diagnose yourself rather than just haul it back to a shop.

Hope ya get it figured out easily!

Always do a break check when pulling out for a day's run (pulling out from brake work...doubly so).

You should feel a strong pull from the trailer when you activate them manually. If you don't, stop and figure out what's wrong.

I pulled into the shop with just the back brakes working. This was a scheduled service as 1st tech did the repair. I hooked up trailer to truck, tested brakes and they were not working at all. I "never" left the shop with the trailer.

What they have told me was they have a senior tech that has now been working on the trailer the past 2 days taking it out for some test rides trying to figure where the problem was and my last conversation was they got half the brakes back working and yeah they mentioned that the problem could be the magnets. Hope tomorrow this gets resolved.

I have never worked on brakes my whole life, rv or auto as this is something I have always had a service shop do.

My last 2 trailers never had issues with brakes. My present trailer sat for 5 years unused as owner had run into a hardship and had to sell. so my guess this probably contributed to the brake problems?

This weekend we are supposed to go to the catskills in NY, so my trip is in jeopardy... not a happy camper...

Ouch. No comment on the shop, as it's obvious. electric trailer drum brakes are about as simple a system as it gets. Either there is power going to them or not and worst case, slap whole assemblies on all 4 corners. They're like $40-60 per wheel, pre assembled ALL components hide hair and feathers.

Use this info dispute any egregious charges.

1. Good wire from trailer plug back to the axles where it splits 4 ways to each wheel.
2. Good wire from there to each wheel.
3. Good magnet and properly adjusted at each wheel (or $34.99/wheel for a whole new pre-assembled 10" brake assembly including backing plate is almost a foregone conclusion if one needs to replace ANY of the components of a wheel brake.

Hope this helps with your ability to get fair and competent results with the shop.

Hopefully, you aren't paying for the re-work because you can get the whole new assembly that just bolts on for not much more than the cost of a brake job...

No idea if this matches your trailer but gives you an idea of how cheap they are:
