brake pedal too high

Always tig weld not mig. Mig welds are to brittle for this use. some of the later cars have a different pedal. The way to tell is the arm is sideways at the pad. Also sometimes that rubber is already in the master . So you need to remove the old one from the rod so it goes in the proper depth. Do not reuse the old rubber or brake failure is sure to happen. There are different length rods. 73 back to 67 are all the same manual disc or drum
