Firstly if I posted this in the wrong thread sorry I did not want to single it only to 5.0 Fox Mustang area, because its a general thing but here it goes!
My mustang is a 1991 Gt, everything is factory OE except for the exception of an e303 cam, cobra throttle body, and 373 gears. It's a 5.0L v8, 5 Speed with 135k original miles.
Since I started my project with this car I have had a brake issue for almost a year now that I cannot figure out for the life of me. Maybe the members here at Stangnet have the knowledge I seek!
---Now to the issue---
When I first press down on the brake it is hard, then becomes "soft" but not like a sponge just "softer" then the hard firm pedal is in the beginning, and yes the car slows down but not good at all, If I am driving at 60 mph and I slam the brakes down as hard as I can.. I can't even chirp the tires to skid or anything. When I let off the brake it returns up with a delay and it again becomes stiff to press down, so I can't do stop and go at all. If I am driving normally and I press down the brake and don't wait for that "stiffness" to go away before continuing then I won't know how hard it will bite the brakes so it's really sudden like a DELAY..
What I have done to correct the problem with no results:
-replaced rotors and pads in front, shoes and drums in the back.
-replaced brake booster, and master cylinder, rebled the lines.
-replaced all vacuum lines on the engine.
and also there is no leaking of brake fluid anywhere at all.
THANKS!! for taking the time to read my problem I hope there is lots of feedback, but again thanks for bearing with me on this wall of text I know everyone has better things to do on their own stangs
