1993 GT, stock 4 lug brakes. I am leaking brake fluid from the area where the master cylinder and brake booster meet up. I believe this is because of a bad gasket, which only cost about $6 at the parts store. Is this generally what causes this?

Also, I really hate to replace the master cylinder because I want to do a 5 lug disc conversion sometime in the next year. If this repair does require a new master cylinder or brake booster, is it possible to use a SN95 setup with the stock 4 lug disk/drum setup?

Thanks in advance!

There is no gasket, there are internal o-rings. You need to rebuild or replace the master cylinder.

No, you can't use sn95 master now. The MC is directly sized to the caliper piston surface area on the car. A 4-wheel disk MC on a car with rear drums will result in a very hard pedal
