I installed a new master cylinder, booster, front brake hoses, new rear wheel cylinders, drums and shoes. I bench bled the master cylinder before installation, and I bled the brakes at all 4's . Now the rear wheels keep locking up, I backed the adjuster all the way down, and they worked fine,
But after about 10 minutes of driving they lock up again. I have been through this about 3 or 4 times now. The first time the adjuster was too tight, But the last 2 or 3 times the adjuster is backed all the way down and they still do it. The brake pedal is way too hard. I need to drive this car tomorrow morning with no problems, What could be the problem here ? All the brake parts are clean, I don't understand why they keep locking up. When they lock up, It's not sudden, They just start to drag and eventually the car won't move. Please help, I think I might sell this car very soon .
