Reply to "Brake power booster rebuild/replace"

panterrorMy 74 GTS

Early Cat,

Sometimes the diaphragms in the booster relax or shift a bit as they age without use. Have you tried shortening the adjustable rod that resides between the master cylinder and the booster? I had the same issue in my car some years ago. If you search this board you will find a measurement for initial length. You can use this as a starting point, but your present setting is likely too long for your current booster. Try backing it off .060" at a time. -Could be an easy fix.

Best,
Kelly
