Default Finally, the brake saga is over... for now at least

Here is the update on my baffling brake problem. Many of you had tried to help me solve the mystery. To review quickly, I turned a drum to .060 in. oversize to get the out of round cleared. Then I could not adjust to get any brakes at all on that side. Many perplexing days later, I finally ordered a set of .060 oversized liners and had them arched to fit my 10.060 in drum diameter at Bratton's mach shop. Now I am sure some of you will see quickly my faulty thinking here, but I did not at the time. Went to install them and I found that I could not get the drum to go over the new shoes with the oversized liners. Finally it dawned on my that by going over by .060 in effect, I went over the diameter my .120. Now what do I do? Well here is what I did. I know it is Mickey Mouse but praise God, it worked! I installed one side with the .o60 over and put the old shoe which had sufficient liner on the other side. Drum went on and I adjusted the brakes. I thought that at worst, I would have to grind off .030 of the Brake Adjusting Shaft on that side and reshape the angle. I could always buy new BAS's if I needed to. I also put a pill on the top end of the operating pin and a pill on the bottom also. I don't like to put 2 at the same end. I had arched the old shoe also to the .060 over drum. My test drive went exceptionally well. Tested the front brakes only first and was able to lock them up and it stopped straight ahead. Then hooked up the rears and now I am getting about 110* +/- on the rear and about 160 +/- temp on front brakes. I am thinking that the Flat Head Ted kit allows the shoes to float enough to make this work as obviously one shoe has to travel further than the thicker one. So far the brakes are working well. On hard braking, no pull left or right and able to lock up wheels on cement with no pulsing due to out of round drums.

I'm glad you can stop again but I need an aspirin.

Me too. Why not just remove the excess material?

If you are .060" over, that means .030" was turned from the wall thickness, and shoes .030" extra thick could make up for it.

Yes, i understand Tom. Just did not think of that when I ordered the 60 thous from Brattons. Even Brattons thought their 60 thous oversize would be the answer. No other size was offered. I think I may have .030 taken off both shoes if I find a place to have that done. Then I will have to re-arch them again. Not sure how or what to do yet. Will a machine shop shave off the linings? .??? Not sure what to do. I have no tools or eqipment or knowledge or skills for machining work.

Do you think as I suggested in post number 5 is the way to fix it right? Will a machine shop or brake shop be able to help?

A brake shop should be able to arc the shoes to fit. The brake grinder I used at the dealership could arc them in a couple minutes. Just set the micrometer to the dimension you wanted, and grind away.

did you make a mistake in post #1 @ 10.060? did you mean 11.060 but now your at 11.120.. your drums are beyond useable safe spec. purchase new cast drums and normal sized linings. have the drums turned and trued / re-arched. frt levers set at 15deg, brake rod from the pedal 1/16th from the frame. all play removed from all the levers and cross shaft. call randy gross

brake only shops are a thing of the past... i dont know of anyone that can arc the shoes and i am in a large metropolitan area...

I had a similar occurrence due to ignorance and bull headiness. I ended up re- arcing the shoes very carefully on a belt sander. Turned out OK in the end after several sleepless nights.
Ignorance is my excuse and I will stick with it.

If you had to take .120 off to clean them up, they must be damaged or warped beyond saving. Replace them.

I took .030 off. Which increases the diameter by .060
