Nissan Repair: Brake Booster leak, nissan pathfinder, brake booster

Question
I have a 93 Nissan Pathfinder 5speed 2x4 that is leakin brake fluid from what appears to be a pin sized hole in the brake booster.  What can I do to fix this?  Thank you.

Answer
Dave,

If you are leaking brake fluid out of the big round black thing that the master cylinder is bolted to it is indeed the brake booster.  That means that the master cylinder is leaking brake fluid out the back and it is getting sucked into the booster and running out the hole.  If this is the case replace the master cylinder.  And, if there has been enough brake fluid leaking into the booster it will eventually fail too.  But, the master cylinder is a must to replace.
