I am going to be working on the brakes on a 1972 1.7 that has not been driven in 25 years or so. I have rebuilt calipers front and back, and the rotors look good. May just need to be surfaced. My biggest question is the master cylinder. Do you think it will hold pressure after 25 years of sitting around. Can they be rebuilt? Or should I just replace it? If I do replace it, do you have recommendation on a model / manufacturer.
Any luck would be appreciated. Steve |

Thank you everyone for the great advice. I called PMB and will be putting together a list of stuff. They also recommended that I get the brake pressure regulator rebuilt due to the time it sat undriven. More work than I thought, but I can put a price on safety.

From first-hand experience, I can tell you that it is far, far easier to replace the brake pressure regulator after dropping the engine. It can be done with the engine in place, but it's a royal PITA! |
