Having never replaced the rubber brake hoses and master cylinder on my 85 GT, I figured it to be a good time, being somewhat fearful of a master cylinder failure while driving (happened to a friend with his 65 GT350).
So…I replaced the front hoses and the rear hose at the T-intersection, plus the steel lines from the firewall back and out to the rear wheels, and the master cylinder. Rebuilt the rear drums. Fully bled the system using a vacuum bleeder. The emergency brake cable lever has resistance when pulling back on it. However, I cannot get any pressure in the brake pedal and the brake light is on (engine running). There are no drips or leaks; fittings are dry.
Can the new master cylinder be bad? I’ve read that one can disconnect the brake lines at the master cylinder, plus the outlets, and test it that way. Seems like it would work, but is there any way to check it out that does not involve opening the system and then bleeding again?
What else can be wrong?
