How to reset your proportioning valve: [ Ссылка ]
Background on this video: I decided to change the brake booster and master cylinder for a few reasons. First, my brakes were feeling soft. Second, the brakes were squealing or squeaking even though the front pads were full. Finally, there was fluid leaking from the master cylinder.
Before doing this job I did a test for vacuum and the motor had low vacuum. That led me to believe there was a vacuum leak in the power brake booster bladder.
