The wedge brakes can be improved. There is an lq4 valve under the dash that disables the front brakes below 60 psi application pressure. It's to stop shuddering in reverse.
Replumbing under the dash allows all the brakes to work.
The "cans" on the backing plates are a certain volume. They can be replaced by bigger ones.
The "pill" in the air foot brake pedal assembly can be changed to add more air quicker.
I had many ommercial truck fleet owners owners who changed theirs,
Brakes get hot and smell. Maybe better shoes and more pressure can improve the brakes and lessen the fade from heating?
Keeping the brakes lightly applied transferred the shoes heat to the drum better than no contact in my testing.
