   It's a hydrovac. Vacuum/hydraulic assist, basically power brakes. Should be a line from the master cylinder output to it, then from it to the brakes. If you have good brakes it's working. Can you disconnect the vacuum line, and plug it coming out of the engine? If your brakes go from good to bad it's working. :hurrican:
