I have a 1992 Chevy Full Size Blazer. Replaced the master cylinder and Proportioning valve and now having problems getting the back brakes right. They don't seem to have enough pressure to them, but can be bled and I have good peddle.

I was told if I removed the ABS module rerouting the lines to the proportioning valve should be sufficient.

Any tips?

I just ordered the gage to check the Power Brake Push Rod Height. In the GM manual it states if it is not within spec to install a service adjustable piston rod.

Where would you be able to buy one? I have searched and come up with nothing.
