brake parts

Does anyone know what make/size of electric brakes are on the 1980 25' International? I need to source return springs, etc. and supply houses need to know what brake I'm working with. Also, these brakes have the round style magnets - should I upgrade to the ovals?

Thanks!

Have you looked into just replaceing the whole backing plate. I've seen them loaded for $55.00 each.
Just a Thought.

My point is why bother with parts when you can get the whole backing plate fully assembled with new parts including the magnets for less than the cost of the piece parts.

Thanks, all. I'm heading to a trailer service dealer today to see what I can get. I think that the brakes might be Dexter ....

We live in western NC, and their seems to be a limited number of distributors close by. I'll balance the part prices against the complete assembly, including freight. Time (labor) isn't a consideration for me right now, as I have time on my hands and am repacking the bearings anyway.

Gary, you make an excellent point. However (you knew it was coming ), in my case, I had one broken return spring in an otherwise functioning system. I would have been torqued if I had had to pay $55 for a spring.

But that is not why I posted. Replacing one backing plate is fine IF your other backing plate buildups are identical to the one you are replacing. Everything I have read in the forum indicates the ones being made today are far superior to the four on my '67 Overlander. I assume superior means they brake more with less current.

So, if I had replaced one backing plate, and left the other three alone, I probably would have had uneven braking. So now I would be up to $220 for a spring.

Its nice to know where to get piece parts

Tom

Tom - my feeling exactly. I now have a second wheel off, and that adjuster spring is broken, too. As with the first wheel, the brake linings and drums are in exceptional condition. I am thinking that the brakes were actually redone 10 years ago, before the trailer 'sat' in a trailer park. I'm guessing that the adjuster springs broke as soon as the PO moved it. The trailer was towed approximately 250 miles last September, and we've been working on it since January.

Your point about the updates is also well taken, as I've read about newer 'oval shaped' magnets vs. the round ones that are installed on it. And of course, that's where things get trickier in deciding how far to go with piece parts vs an assembly. I'm not terribly impressed with the brake effectiveness in general. Although there is no 'pulling' to one side or the other, and no grabbing, I feel that the brakes should be 'stronger' than they are. I'm looking at the magnets now, and it seems to me that the friction surface is only marginally above the screw heads. I'm not sure just how much wear is advisable before replacing the magnets, but since I am taking everything apart anyway and there may be a better component (magnets) available now vs 25 years ago, maybe I should consider replacing those, too.

I can get a complete spring set for about $4 per wheel. Plus magnets (possibly) - that is what I'm weighing against the assembly cost. Again, my time is 'free' right now, and I've done lots of brake work over the years - albeit hydraulic brakes.

Tom, Jay and Sue
I hear what you're saying, I would only go the loaded backing plate route if I new the springs, magnets, and shoes were in bad shape and should all be replaced. Just one or the other I probably wouldn't replace the assembly.

Hi Gary
thanks for the info on Dexter brake assembly. They were only 49.90 each. On my 1985 A.S. the round magnets were gone and when you figure out the price on
seperate parts the brake assembly is the only way to go. Dexter brake are easy to install and they have dealers all over the country. They also sell on the net. russ
