I have replaced the master cylinder & bled it & the lines @ the wheels but I have no brakes. I bled the master cylinder under fluid came out, same with the lines. The bleeder bolts were stripped so the "housing" has been replaced on the front brakes. I bled the lines, no pressure so I bled the master cylinder again while on the car then the lines again. With the brake to the for the car can be pushed! Please help!
