Model T Ford Forum: Forum 2018: Squeaky Rocky Mountain style brakes

I have a Model T era car with outside drum brakes similar to the Rockies on my Ts. They squeal something awful when normal pressure is applied. Is there a different band material used on steel drums than on cast drums. This material has small brass fibers imbedded in it. Should I get a different material for the bands?

If you still have lots of friction material left on the bands, you might try sanding the surfaces of the bands and drums, that might remove the surface glaze and quiet things for a while.

I have not had any squealing problems with the "green gripper" lining material for my AC brakes that I got from Chaffin's. It is green (go figure) and has brass fibers running through it.

Bud Williams sells a molded material for his Rocky Mountain re-pops that does not squeal but it is really temperamental and if ANY oil AT ALL gets on it, it dissolves into a goo. Most woven lining has a brass thread in it and is usually used for truck parking brakes on drive shafts and not for stopping because of its nature of making a noise at speed. If you could get a solid cast materiel and have it bonded to your lining you could reduce the noise. Remember that brake drums have been used for dinner bells for well over a hundred years for a reason.

Mark, you are right on that one. We had some clutch disks made for our two cylinder 1906 Moline with a dry disc clutch outside of the planetary transmission and it lasted a long time. It was green just like the material Chaffin's Garage sells.

squeeling is the nature of the beast! I can remember hearing brakes squeel when I was just a boy and when we played with cars, we squeeled whenever we pretended to stop. There was a stop sign about half a block away and almost every car squeeled, especially the Model T's.

I just live with it and if I hear them squeal at least I know they are doing something. :-)

I agree with Mark G. & Norman. Let'em squeal. It reminds me that they are working and announces our approach to an intersection. I consider it a T "feature" and not a bug. SKREEEEEEEEEEECH!

How about calling them outside brakes? No brake can be Rocky Mountain style except real Rocky Mountain brakes!
