1980 Vette Brake problem
I am trying to fix the brakes on an 1980 Vette that had sat a while. When I got to it the master cylinder was bad and all the fluid and ran out the back of the master cylinder. So I replaced that, bench bled it, Started bleeding the brakes. Front bled out nicely and pedal started to respond. Got to the rear and could get no fluid out of the bleed screw. Also noticed the caliper was not moving. Unhooked the brake line to the master cylinder and was getting fluid to the caliper just not thru it. Removed both rear calipers and rebuilt them. Reinstalled on the car and now I am just getting a dribble of brake fluid to the calipers no pressure despite many many attempts at bleeding. Replaced the proportioning valve. Even blew the line out from the valve to the rear of the car with both lines unhooked to verify there is no abstruction. Ran out of brake fluid today. Tomorrow the only thing left is to verify the new master cylinder is pushing fluid out to the rear and blow thru that line down to the new proportioning valve. Am I missing anything?
