When the engine is not running the pedal feels as it should put your foot down on the brake hard and it goes down aprox 20% and is firm. If I turn the engine on the brakes dont feel right at all, I put my foot on the pedal the brake pedal will slowly depress to the floor.[:^(] I changed the rear axle on the car as I wanted to have a rust free one and I fitted a set of poly bushes while I was on, I also got hold of a set of rear brake callipers of a friend who was braking a car, I was told they worked perfectly fine before they were removed. I cleaned the brake callipers and painted them and fitted them to the painted rear axle then fitted them to the car at the same time I fitted a full set of Goodridge ss hoses. The system was then bled, using a one man brake bleeder. All seemed to go ok till I turned the engine on. So I got hold of a easyblead and bled the brakes again, the brakes still dont feel right with the engine running. I bleed the brakes with the easybleed and the engine running could not get them to feel right but there was no air in the lines and the brake bias valve was fixed closed. The rear callipers are set to 1mm and bled with out the hand brake cable attached. Can anyone please advise what I should try next, as I feel that some how the master cylinder is not working, I cant see a pressure leak or anything thats loose.
To bleed the rear brakes the rear axle must not be hanging or the brake bias valve (which is fixed to the passenger side of the axle) will cut the amount of fluid going to the rear brakes, and they won't bleed properly.
