Brakes on my 70 Mach 1 are holding at times. This has just started. I notice it when I let the clutch out. It is a 351C 4V with facotry power front disks. Any ideas? Master cylinder need replacing? Seems like it it is holding pressure in the lines. I haven't bled the lines yet. That was going to be my first step to see if I had any trapped air that could be heating and expanding.

Two things come to mind ... the booster could be bad, or the pushrod between
the booster and master cylinder has somehow "lengthened' .. it is adjustable
and needs to be set properly to avoid preloading the master....

If the problem is evident with the car stationary, you can loosen the 2 master
cylinder attachment nuts and see if that loosens the brakes.....
