I've been working on this a while and am out of ideas..
The pedal goes to the floor but can be pumped up. The problem resets upon acceleration.
Replaced the master cylinder, no change. Bled the brake lines many many times. Not seeing any drop in the resevoir over time so I think theres no leaks.
Replaced both wheel cylinders and cleaned off the flywheels. But that's where the problem really is i think.
I've noticed the flywheels reset over time. Not sure why. There is some uneven wear on one of the shoes, so I thought wheel bearings? But when I brought it to a shop for new bearings they said the were fine and just adjusted the flywheels, which I told them I had been doing but whatever. A week goes by and the brakes sink again.
Just to be clear, adjusting the shoes via the flywheel works, but only temporarily.
And just today, to top it off, a loud metal grating sound started in the rear passenger side while driving, not while braking. Theres a good deal of shoe powder in that drum, and a rough texture in one section.. this is new.
What could be causing this deeply troubling behavior?
