Woven vs molded linings for cast iron drums

[Fordestes]

Anybody used the made in Germany molded linings that are sold by sniders? I am changing to cast iron drums and am thinking about trying them, any opinions on those particular linings ?

Asbestos-alternative brake linings are more expensive but have equivalent or better performance.

Hey Alex, What is the source for the asbestos alternative brake linings?

I have Snyder's molded brake linings on my Town Sedan. I didn't know they were made in Germany until I read your post. I believe they work better than the woven linings I had on the car previously. I have Cast Iron drums.

I did notice they squeal a little when cold but that goes away after a couple of stops. And they smell.

Asbestos use has been banned here but not in the US it seems, tho unlikely to be used now.

You never know where it will turn up.

Don't breath asbestos dust. When you die it will take 3 days to cremate you.

I appreciate all the comments. I replaced the rear brake shows with woven linings I got from a fellow club member. We shall see. I took it on a test drive and everything seemed fine except that my left rear shoes are too tight in the drum. Quite the learning experience for me. As much as I love the Les Andrew red book, his section on replacing rear brakes shoes is not very complete.

One related question: The red book says that when you use the brake centering tool to bend the tabs on the shoes if they are not centered. What tabs is he talking about? I didn't see them.

I believe he is referring to bending the roller tracks to center the shoes, not the bending the shoes themselves.

I remember years ago they made a cast iron ring that pressed on the steel drums. They supposedly made a huge difference. Are they still available or is cast drums the only option? Just curious.

Yes, the brake drum reinforcing band for the steel drums are still available from some vendors.

Thanks!

Update: I picked up some woven linings from a Model A club friend for my back brakes. I got everything done, but my driver's side drum was too tight, so I couldn't take my car to the show the next day. I disassembled the brakes and sanded the linings some. I also adjusted the brake rod and added an extra axle shim as I could see that the linings were rubbing agains the new drums. That seemed to do the trick and on the short test drive, I have lots of brake pedal and good stopping. I will drive it some more tomorrow and I should be good to go for the parade on July 4.

Update? This is a job I have coming up.

In late 1931, ford introduced cast iron drums for front wheels only. I have never heard any comments on them recommending anything other than regular woven linings

I scratched my head over this question a while ago. I decided to buy the drums already mounted on hubs from Randy Gross. He advised woven linings in cast drums. I took him at his word.

Really? The brake shoes Randy sells are Molded and Bonded.

For future reference, the coefficient of friction can be measured by putting the sample on a piece of cast iron or steel and raising one end until the sample slips. The coefficient of friction is the tangent of the angle when the sample slips. The amount of weight on the sample does not change the physics or math but more weight may change the coefficient of friction.

Oh my head hurts. Samples, angles, coefficients, weights, slipping, physics, cast iron, steel, tangents.

All of the brake shoes in our stock and every job that leaves are shop are of a soft composite material and bonded. Both the leading and trailing edge of the shoes are chamfered. We have been using the same material for close to 20 years now with great success.

My Mintex Brake Service Guide says:

"The most common cause of chatter and groans is the lack of centralisation of the brake shoes due to wear of the shoe support bracket"

It says you can use an over size pin of 0.020 in the rollers of the brake shoe (oversized pins have a depression in the head)
Or
"The worn ears of the shoe support bracket may be bent upward. A small crescent wrench is a handy tool for this"

Now, I'm really confused.
