Electric Trailer Brake Assembly


Senior Member
Believe it is about time for new brakes on my 5 yr old 5er. I have read on one the RV forums about how it was easier and cheaper to just replace the whole brake assembly. Unbolt the old assembly and bolt in the new. The new assembly includes new brake shoes, magnets, hardware etc.

Has anyone done this? As easy as it sounds?

1) Safely jack the trailer up and block
2) Remove wheels
3) cut the 2 magnet wires in a good position to splice back together
4) remove the bolts attaching the brake assy to the brake flange
5) install the new brake assy then steps 1 - 4 in reverse

Yes just did two out of four on my trailer. My fault I have wet hubs ans I let them leak(another story on what NOT to do) Mine were $79 per wheel and as above off, on, adjust if needed, check operation. If it were not for the grease to clean I would say an hour of work and an hour of prep. Air or speed wrench is a real help. I did replace the bearings while I had it apart just CUZ for me if I didn't I would soon(my luck and only a couple xtra bucks).

Took off one of the drums Saturday and found several things...The brake shoes were ok, the bearings were almost dry and the D washer was warped in the center. I am assuming the people who worked on it last must have really tightened it down. They were suppose to have re-packed the bearings, but does not look like they did a very good job.

Several years back had the dealer look at the brakes. The Tech says that the magnet(s) was not working as well as they should on one or more of the wheels. They met minimum requirements, but would soon need replacing. I have had to crank up my brake controller to the max to get ok braking from the 5er. So, I am assuming they were right.

Even though the brakes were ok, decided to go ahead and replace all four wheel assemblies. To replace the magnets and for piece of mind if anything else. Have to re-pack all the bearings anyway, so figured it is a good time to do it. RV is 5 years old...should be good for another 5.

Assemblies were $55 a piece with free shipping from etrailer.com. Should be here Wed or Thurs. I know what I will be doing this weekend.

Thanks for everyone's replies.

Wheel assemblies installed, bearings repacked with new seals, installed new breakaway switch (old was bad), had battery door re-painted. All set for our trip next week.
