Electric brake testing on old trailer

[Diamondpilot]

Well the good news is everything is there. Bad news is its old and rusty. I have never seen round magnets. Most are oval now days.

ok, here 's a few more. Drum is 10 " .

Those drums can be cleaned up and used. May need to turn them at a brake shop but I would go though the bearings and clean, inspect, repack, and new seals.

10" brakes are still used so getting parts should be no issue.

If it was mine, I'd just go buy all new complete backing plate assemblies. Not that expensive and far less work than cleaning all of that up.

Yep, and one of the springs broke off when I grabbed it. Thinkin' about the backer plate thing some one posted and wondering if the best route would be to install brand new brakes. Is backer plate a part of the whole brake unit so that it all comes off if plate is removed ? Can you point me in the right direction on how to remove the junk brake system and put new one on ?

How many lug are the wheels? 10" trailer drums should use a 154 brake shoe kit. For example at Napa they use True Stop brake parts so it would be TS-154.

Auto Zone may use Bendix sot he shoe part number will be BEN-154.

The good new is most trailers use Ford parts for brakes. Knowing this can save you a ton. You can get shoes, springs, ect at your local auto parts store. Something like a 68 Falcon used 10" drums in the rear if I remember right. Have the parts guy do some checking.

154 brake shoes are 10" x 2.25" wide.

Remove the 4 nuts on the back side of the backing plate, and remove the backing plate as an assembly. You'll have to cut the wires for the magnets also, but if I remember correctly you said they were already cut.

Brian is probably right.

Go to http://www.randpcarriages.com/ for good service and fair prices.

Nice help section on how to install a controller, fix your brakes, wire your trailer, ect.

Diamondpilot I thought some pix would better serve as to you lug question. They 're actually 4 bolts through the wheel into the drum. Thanks for the link to trailer parts.

Yep, wires were cut. Got about 2 inches sticking out back side. All brake wire that lead up to tongue plug was also removed. I think as you said it would be less work and stress intensive for me to just install new brake system. I got no desire to try and restore the old system.
