Slow Brake System Leak

[boothill2008]

Help!!! I noticed my brake master cylinder has needed filling about every 2 months, I don't see any obvious leaks from the master cylinder, and no fluid is visible weeping onto the wheels, what's the best way to troubleshoot this leak??

 

Thanks, Boot

maybe you are wearing your brake pads insanely fast... could be leaking into your brake booster..

Pedal feel change at all? Pull the screen in the MC and watch the fluid in there while someone else pumps the brakes, and then watch while they push and hold the brake. If you see any bubbles you have a leak between the booster and MC. If not start bleeding each wheel to see if you find any air bubbles, if you do, then trace that line.

Pay special attention to the rears if you have drums in the back. Wheel cylinders can leak into the drums for a surprisingly long amount of time before it becomes obvious.

check your pass frame rail for rear anti lock block may be leaking from there
