I have a 37 Ford with disk on the front and drum on the back. I swapped out rear ends (1987 olds 3.23 to a s10 blazer 3.42) and now the rear brakes wont lock up. They barely come to stop when the car is on jack stands. I had good brakes with the Olds rear end.
The system currently has;
Dual disk/drum 1" master cylinder
Proportioning valve
Risidual Valve
I installed new wheel cylinders and shoes prior to rear install
Replaced master cylinder
Took proportioning and residual valve out of the system to test
Bled system many, many times
I am getting 600lbs of pressue at the wheel cylinder
At this point I can't help but think it is mechanical.
Any help at all would be much appreciated, before this old man pulls out what little hair I have left.
Thanks in advance for the help.
