i posted a few weeks ago about my DA loosing breake pressure and having to pump thebrakes to get some pressure back in order to stop the car. this weekend i put in a brand new Master Brake Cylinder and a Brand new Brake booster i've checked for leaks in my lines and bleed the **** out of the system, i used 2 1/2 bottles of brake fluid. only thing i can think of is to changed the front calipers, anyone have any suggestions or has any had this problems??
