Rear disc brakes

Has anyone used wilwood brakes on a Maverick we put a 8.8 rear end and put brakes on change the master cylinder one for front disc brakes but the rear brakes want to stay locked up doesn't want the Roll free any suggestions

 

Proportion valve ? Lines in good codition ?

 

Your sure brake is locked and not the rear end having a issue ?

 

If you have a disc/drum master cylinder there may be a residual pressure valve on the rear line.

 

Everything is brand new thinking it's just tight to the hand turning it. We will find out more when we can crank the car and running. Thanks for all the replies

 

if the rotor turned free and it's just tight to turning by hand with calipers and pads installed, it should be fine...
