Yesterday I had the master cylinder replaced in my 1965 Mustang. It corrected the brake fluid leak but my power brakes did not return. With further investigation, the mechanic determined that my booster is inoperable. While it appears standard to purchase the master cylinder on its own, it seems difficult to find a booster on its own. My only option appears to be pulling my existing booster and having it refurbished. It's not cheap to do not to mention the turn around time. Any other suggestions out there?
