I just installed a new booster and master cylinder from WCCC on my 67. New pads on the front, new wheel cylinders on the rear and new hoses front and rear.
The front bled with no problem and are working great.
No matter what I try, I can't get fluid to the rear wheel cylinders.
I've done the two man pedal pumping method and the vacuum pump on the rear bleeders and even pulled the hard line apart where it goes to the hose to the rear axle and hooked the vacuum pump up there and still get nothing.
It holds vacuum and won't pull any fluid through.
Does this sound like the proportioning valve at the back of the car has siezed up?
It hasn't been driven in a couple of years and the c4 is on my workbench right now getting rebuilt, so I'm trying to get it to go and stop reliably all in one shot.
Thanks,
Robert
