Re: poor braking
Many moons ago when I worked on cars for the general public, a customer brought in an early '70's Dodge van with a leaking master cylinder. We ordered out a new master, the parts house delivered it, we bench bled it and installed it, and all was fine except that you couldn't stop it without the brakes grabbing so hard it wanted to put you through the windshield. Calling the parts store and re ordering it and returning the first one revealed that the first one was for manual brakes, not power. It had a smaller bore and that caused there to be much more line pressure than the larger bore unit intended for the power unit.It may have been packaged wrong, who knows now. There is a decided difference between manual brakes and power assisted brakes as to the bore diameter.
