I have noticed the M/C losing fluid lately. I have found that the back of the brake servo is wet with brake fluid. I have about 1000 miles on a new M/C but have been using an unknown booster that was with the car when I bought it. I am guessing that both the M/C rear seal is leaking as well as the front seal of the booster otherwise how would brake fluid get into the booster. My thought is to replace the booster with a new one, given the unknown nature of the beast, but not sure what to do about the M/C as it was purchased from Moss several years ago but not put into service until last year. Is my thinking sound or is there an 'easy' fix by simply replacing seals?
