Brake Linings

[jeepguy1948]

I need to recline the shoes on my old Jeep brakes and I’m wondering what code linings I should get (and if one brand is better than another) FF, GG, etc. I is my understanding that the FF is a softer material that provides better braking but wear faster. There is also EE and maybe more. The Jeep rarely goes fast enough for there to be enough braking to raise the lining temperature enough for some to work properly. Yes, I know, it’s not a Ford but the principles are the same this is the community that i know. Thanks.

Hey Guyz, that was great information that you provided but somehow (I have no idea how) your post’s got deleted so if you would please re post them I would appreciate it, Thanks.

I’m bringing this back up to the top in hopes that somebody can help me out after dummy me deleted the original responses (still don’t know how I did that).

Jeepguy - I'd go with the softer lining material for general driving and cruising. As for brands, I have no idea. The harder lining material usually takes more brake pedal force.

Ford did make jeeps during WWII. The chassis parts were made to be interchangeable between the two manufacturers after they were put into universal design. The early ones had differences but most were common. The Willys CJ2 isn't a lot different than the wartime Willys. After the CJ2 they started making more changes. Make sure all linings match and fit the shoe profile. Woven linings are fine. I'd avoid the real hard ones.

The final two letters in the edge code (EE, FF, FE, GG, etc.), simply represent the coefficient of friction values taken from a standardized Society of Automotive Engineers (SAE) recommended practice.
The first letter denotes the normal coefficient of friction (temperatures ranging from 200° F to 400° F) and the second notes the hot coefficient of friction (ranging from 300° F to 650° F).
The edge code letters are directly tied to that formula, where Fn is 150 lbs. and Fr is the pressure recorded by the load cell during a normal or hot test sequence. E equals 0.25 to 0.35; F equals 0.35 to 0.45. For example, an average load cell recording of 42 lbs. per square inch during a test would produce an m of 0.28 that would relate to an E rating on the edge code. If that’s recorded at both temperatures, an EE would show up on the pad.

Thanks, but that raises the question, what do I want?

If you call Brake and Equipment warehouse in MPLS and tell them what you are working on, etc, they will know what to do. Been in business for ever, they have done my shoes since I was a kid. Used to drive there, but now you might get killed !
