I replaced the power assist unit in my 67 Mustang with a rebuilt one as the previous one was leaking.There is now at least an inch of free play in the pedal with the engine running which causes a very uncertain braking feeling! The free play returns slowly after the pedal is depressed. I Removed the master cylinder and checked the power unit pushrod length with a gage as described in the Ford manual and the length was perfect.I also re-bled the brakes and no improvement.Any suggestions would be appreciated.
