I recently bought a 69 that had very little brake pedal. The previous owner had just replaced the booster & mstr cyl before I bought it. I did not ask why they were replaced(stupid on my part). I assumed the guy did not know how to bleed the brakes. The brake pedal goes with in an 1/2" of the floor before the brakes will start to work(you sure don't want to be going very fast & try to stop it???)I have since replaced both the calipers, rotors, rr whl cyls & used 3 new, not remn mstr cyls. I have bench bled the mstr cyls, used a Mighty Vac pump to bleed the brakes, still no pedal, I have also used a pressure bleeder(30 psi) to force the air out, still not any better. The calipers have the bleeders at the top. Does anyone know how long the rod from the booster to the cyl should be & how about the rod out of the back of the booster?? The assy on the car now has 4 5/8" rod in the master cyl(The cyl has the deep hole, 1 1/8 bore). I also removed the round proportioning valve, no help. This car is a 4 speed,not sure its original set up, I don't know if the pedal assy is correct for the car, is there different year model that would physically fit, but not work properly?? Pleae help, Thanks
