Brake Question

Ok.. I had my brake booster rebuilt about three months ago.. Put the master cyclinder back in the booster and bolted it back up.. Well lately I guess I just noticed it but brake fluid is seeping from where the master cyclinder and brake booster meet.. What are some problems here? What should I do? 78 CJ7 w/ large 6bolt Discs Front, Drums Rear..

thanks

Re: Brake Question

sounds like the master cylinder is leaking at the rear.

Re: Brake Question

The plunger is gone inside your master cylinder. The only fix is replacing the master cylinder. You can probably get a rebuild kit. But the master cylinder is cheap enough that you should just replace it.

Re: Brake Question

If you replaced the MC at the time of the rebuild you Probably had a bur in the Master cylinder wall and with a few miles on it the seal on the piston is scored and has started leaking. It will only get worse. That is a risk of buying the remanufactured ones but it should have at least a one year warranty on it. If it is old it is probably just ready to be replaced. If you haven't done much mechanicing this would be a good job to get your feet wet on. With the help of this board. It's pretty simple.
