Master cylinder swap now having problems brakes sticking.

Have you adjusted the push rod length to stop the master cylinder from being on? if nothing has changed on the brake system,and the only change is the master,either the master has a problem or its partially on and dragging the brakes.A simple solution is to add flat washers behind the master to see if the problem gets less,this shows the master is not releasing the pressure,and by adding more washers,shows the problem is gone ,but needs a adjustable pushrod.If the problem does not get solved with the washers,the master is at fault,by not releasing the pressure inside.Jack up the front end and pump the pedal and see if it sticks,loosen the master cylinder two nuts 1 turn,do the front wheels still stick,go a another turn,you know what the problem is,mrmopartech
