I recently purchased a 1973 Javalin w/ 360 4bbl. All smog stuff has been removed. My master cylinder leaks fluid out from underneath the cover. Any ideas what is causing this? The car has front disc brakes. any help would be appreciated. I put a new pice of vacuum hose from the brake booster to the intake which is an edelbrock performer. from the looks of the outside of the master cylinder and the inner fender its been leaking for some time.
