The brakes on my 80 have always been lacking in stopping power and I wondered if maybe the proportioning valve was to blame.
I am in the middle of replacing the rear axle seals on my 80 and also replacing the rear brake pads which requires the caliper cylinder to be pressed back in (i'm using a C clamp for this). Out of curiosity while the caliper is off, i had an assistant lightly press the brake pedal and i noticed the piston did not move. The brake pedal had to be pressed down considerably before the piston moved much at all.
I'm wondering if anyone else has experienced this? Has anyone had success replacing or updated the proportioning valve or maybe the master cylinder or is abs limiting pressure somehow? Whats the best way to test pressure without a pressure gauge?
Thanks in advance for your help.
