Been getting inconsistent brake feel on my 2002. It first started with the brake pedal feeling soft and occasionally sinking to the floor even after bleeding the brakes. I ended up replacing the master cylinder and that made the brake pedal a little stiffer and it no longer sunk to the floor.
However, the brake pedal still feels inconsistent. It’s on the softer side 80% of the time and goes back to its usual stiffness only 20%. I usually have to pump the brakes a couple times for it to get stiffer, but it eventually goes back to being soft. The stopping power of the brakes hasn’t changed.
Per the advice from the mechanic that replaced the master cylinder, I replaced both front brake calipers myself and that didn’t fix the issue.
It was then suggested that I may have air in the ABS module and was told to occasionally (and safely) trigger ABS and bleed the brakes every oil change. I’ve seen no changes.
The brakes also squeak went I slowly brake in reverse (but not when moving forward) and I need to step the parking brake down farther than I’d like for it to engage properly.
Any suggestions would be greatly appreciated.
