I needed brakes on a XJ, so I replaced the front calipers & rotors, pads, a new master cylinder and new power brake booster. Since then, I have a ton of air the front brakes. I get decent brake pressure when the motor is off, but as soon as I start it the pedal goes to the floor. I used a one-man bleeder and then tried it the old fashioned way when someone pumps the pedal while I do the bleeder screws. Either way I have no brake pressure. I am at a loss right now. There is a ton of tiny air bubbles coming out of the lines and there is a ton coming out of the reservoir too. There is no brake fluid leaks. What do I do? Does the system need to be pressure bled?
