Hey, Last year we replaced the brake system in my car...larger drum brakes on the rear and discs on the front. The brakes have worked fine until last week when the brake pedal got soft. We bled the brakes, but cant get the air out of the left front. It isn't large air bubbles but fine bubbles the fluid is almost white... All others lines are clear fluid. Any ideas? Thanks
Was the rear half of the master low on fluid?? Assuming you have no small leaks visible you could be getting air in the rear of the master past the piston. Have a close look for fluid at the push rod area of the master. Also pop the wire off the switch on the prop valve and check for fluid seepage.
Thanks for the suggestion. We aren't seeing any fluid around the proportioning valve. THe master cylinder is under warranty so i am going to swap it out and see if that fixes the problem.
