There is usually a check valve between the front and rear brakes. It is common that they get air-bound. You should try to bleed them a lot with a vacuum bleeder if you can get one. Or just pump and pump, and bleed the old fashion way. Please award points if this helps
there is no check valve in the car.......barkes are directly attached to master cylinder......
did you blead theair out of the system,did you beanch blead the new master cylinder befor installing,if not get a bottle of dot 3 break fluid get a friend to help,one pump up break peddlethe other do the bleading,keep doing this to all 4 wheels until all the air is out.
Yes i did blead the new master cylinder......but still
