ccwade81 Posted December 21, 2019 Report Share Posted December 21, 2019 1973 620 - Bought truck about 4 years ago and brakes would only slightly work when pedal was on the floor. I have since replaced master, booster, rear cylinders, rear shoes. Front shoes and drums replaced by PO. Bench bled master, set adjusters at all 4 corners, bled system. Pedal is soft and truck doesnt stop until pedal is bottomed out. Pulls about 18hg/in vacuum at idle, booster check valve still good. I'm at a complete loss, I just want to drive my truck! Please help! Quote Link to comment
