In your other post you said that there was a valve in the line to the rear--remove it, it can only reduce brake pressure--------

You said that after a tight slow speed turn that the peday goes to the floor---check for rotor run out---pushes the pads back into the calipers

Are these dual piston fixed or single piston floating calipers???

After a couple of stops, check the temp of the rotors with your fingers----------be careful, but a burnt finger is what you want!!!!!!!!!!

What brake fluid and have you ever mixed tem???? brands/types??????
