disk brakes conversion no pressure to back brakes
I've just installed a set of disk brakes on my '69 Chevelle. Once complete I bled the brakes. I am not getting any pressure to the rear brakes. The front seem to be working fine. I get a trickle out of the rear brakes but not the pressure that it should have. I left the existing proportioning block on and installed a balancing valve between the block and the rear brakes as noted in the instructions. It just doesn't add up. Anyone got an idea.
