brake probs

[240DRFT]

have anyone ever had problems with their master cylinders leaking??? theres a leak where my master cylinder meets the brake booster and i need to know if its just like a gasket or if its like i need to replace the master cylinder. can anyone help me to fix my problem

just replace the whole master cylinder; i got mine's replaced w/ a rebuilt unit... lifetime warranty (w/exchange of the old/leaky unit) raybestos/pepboys...

u can rebuild yours w/ a kit as well, but i like the fact that if it will leak again, i can just whip out my receipt to get another one fo free.

There isn't a gasket between the two...

The only gasket is on the opposite side of the booster. There are two seals underneath of the reservoir, maybe the back one is leaking and it looks like it is coming from between the brake booster and master cylinder?

Theres a thing called a stopper cap on the back side of the master cylinder where it meets the booster, maybe that is causing it.

Sorry I can't diagnose it, but thats all I can think of.
