Hi Bill! You might try the woven livings. C&G shows them for your gorgeous Merc as 21A2001-NBD, $69.95/set. That also includes the rivets, I used a set on my 1930 model A years ago. They don't last quite as long as the bonded type, but stopping is much improved.

I have the same question. Why cut the drums? Replacing the shoes is far less expensive than drums. Additionally replacing old brake drums with new ones is a big and costly ordeal. As I said in a earlier post check the shoes to make sure they are the proper ones and arc them first before cutting the drums!

blarge. If your drums are true and round, why would you cut them OS? All due respect, it would be better to have the linings arced to the correct diameter. You can get new shoes/linings, but once you cut the drums you cant go back. Just my opinion.

Bill, Fort Wayne Clutch used to reline shoes, but they sold off that business and i can't remember who took it over, but if you give them a call, they might be able to recommend someone. Here is a place closer to your home. A local relining service recommended them several years ago, but I did not use them. Give them a call and explain your problem to see if they can help you. http://www.midwestbrake.com/index.php

Bob: Nice to hear from you again. Where would you recommend that I purchase "softer " linings? When this all started two years ago, I bought a set of linings from C&G, but they were to thick to allow the drums to be installed and I never got a chance to see how effective they were. My current plan is to have the drums turned to be .030 oversize so replacement linings will allow the drum to go on. I would like to get softer ( more deceleration with moderate pedal pressure) linings too. Do you have any additional ideas ? Thanks, Bill Large

If the shoes have bonded linings, it is likely they are too hard. That is OK for non-power brakes, but not for our old cars. Usually the clue is that the shoes are not riveted if they are incorrect. Regards, Bob

Hi Bill, give me a call, I have the gages to measure the shoe radius and the drum diameter. Paul in Jackson

I just had the same issue with my '47 Ford 2 door sedan. After a lot of trial and error found out the work I did was fine but Ecklers/Mac's sent the wrong shoes. When the shoes are arc'd the radius of the shoes surface should match the inner diameter of the drum. I measured and found the contact point at the top of the shoe was just about touching the drum and the bottom of the shoe had an 1/8th gap between the shoe and drum. My car has the standard Lockheed brakes not the self energizing Bendix brakes; I think your Merc has the Lockheed brakes as well.

Had a similar problem on my 48 and talked with Bill Large about it at the time. The reason I had to replace the front shoes was a leaky right wheel cylinder. After all sorts of messing around (there was a discussion on the forum about it at the time) I realized that the replacement front shoes were not the same 'brand' as the ones I took off. They were not worn, but the right front was wet from the brake fluid leak. I spent a lot of time soaking and drying the wet shoe and finally put those originals back on. These were identified as Ford shoes - but who knows. Anyhow the brakes then worked fine, were balanced and did not pull. My only thought was that using different 'brand' shoes front and rear created the very bad imbalance I had experienced. Bill Carry
