Model T Ford Forum: Forum 2015: Kevlar lining on emergency brake shoes

Has anyone tried to use Kevlar lining on the e-brake of a 26-7 T or on a TT truck? My first thought is it's not the correct application, but why won't it work? It conforms to the curvature of the drum, resists heat, and can be riveted in place. I know people use it to replace leather on cone clutches so why won't it work on the E-brake. I know I'll probably get severely chastised for even thinking this will work, but I guess you never know if nobody asks or tries.

This was posted on an antique car forum several years ago...

Model T Ford owners use woven 100% DuPont Kevlar (aramid fiber)linings.

Kevlar has unusually poor abrasion properties and will fray and tear when used in any dry application.

Kevlar used in the Ford T transmission is bathed in oil. ..... others have tried the same woven Kevlar in early open (dry) planetary transmissions and the Kevlar lining was destroyed in less than 500 miles.

I ordered some AC brakes several years ago when they put Kevlar on them for a short time. The linings had to be replaced to get effective braking. The dry Kevlar got hot and melted in use and did not hold well.

Thanks for the feedback!! I guess it will only work if my rear axle seals are worn out allowing the brakes to be bathed in oil!! LOL!! Question asked and answered. Thanks MTFCA
