Ron,
You state the piston doesn't return to it's full forward position. Do
you rearward position? If so the piston seal hasn't returned to a position
that will uncover the compensating port between the reservoir and the M/C.
Look for a restriction in the mechanical parts. The return spring may not be
strong enough to fully return the piston past the compensating port or the
piston may be binding in the bore.

Front disc brakes locking up after rebuild
Folks,
After rebuilding the
hydraulic system the front brakes do not release. If
the bleed screw is
loosened, they do release.
The rear brakes do not lock up
All rubber hoses
were replaced.
All original steel brake lines were clean with air pressure.
The connector valve on the passenger side was removed and cleaned with air
pressure.
The caliber pistons can be moved by hand when they are off the car.
When the front brakes lock up, the master cylinder piston does not return to
the full "forward:" position.
Any suggestions would be greatly appreciated.
Thanks
Ron
