split the MC and booster & measure the rounded booster pushrod nub clearance to the bottom of the MC rear piston "thimble". want ~.020" Yes, you have to have some free play between the pushrod and the master cylinder. Otherwise it just continues to build pressure and never releases correctly. Check that first before you do anything else. The pushrod should have an adjustment on the end.
