My 89 B2200 starting leaking brake fluid when parked between the master cylinder and the brake booster. After looking at my Haynes repair manual, it does not show any seals between them. Does anyone have a suggestion as where to start? Or should i just replace master cylinder? The brakes seem to working fine when driving but I don't want to wait for a failure.

Hi Hawk and welcome to the forums!! It does sound like the rear seal inside the MC is bad, I would also double check the cap of the MC just to be sure its just not simply leaking in the back and running down.

 

Thanks for the info, I finally got around to replacing the MC and that did the trick. Bench bleeding and installation went flawlessly.
