1967 Mustang with 1989 5.0 drive train (motor and AOD)
Originally the car was a 4 wheel power drum car, I change this to a power from disc and rear drum car. Now here is the problem, I HAVE NO POWER ASSIST! Here is what I have done and changed to no avail:
1. Power booster 1st rebuild original, no help
2. Replaced booster with period correct one, no help
3. Replaced master with period correct one, on help
4. Changed pedal to period correct one, no help
5. Checked booster vacuum (17.5 PSI)
6. Add vacuum pump to check, (23 PSI) still no boost
7. Checked PSI at Calipers (1000 Psi front) and (700 PSI rear)
8. Checked proportion value, not tripped to front or rear
9. Front disc are four piston from SSSBrake older 1990’s
Please help?
