A-Body brake help
Put a 15/16" bore manual master cylinder on it. You probably have a 1" or 1 1/16" bore manual master on it now.
Put the new 15/16" bore master on it and it will feel much better control, and less foot pedal pressure required to apply the brakes.
Almost like power brakes, but with the simplicity of manual brakes. The smaller bore gives you a longer stroke, and more leverage with your foot to apply pressure to the brake shoes.
Fits the A bodies manual drum/drum
We use same one on the manual drum/ drum B bodies too.
