OK best way to explain my brakes seem to start grabbing slightly causing them to overheat. This seems to happen off and on in conjunction with the stiffing of the brake peddle. If I put enough force on the peddle to put it to the floor it seems to unstick the brakes. But I seem to lose brake fluid when I do this which causes my brake warning light to come on and then lose my brakes all together. Filling it back up corrects the warning issue.
I have replaced the following , both calipers , front brake hoses,new pads and master cylinder
I have also bled both front and rear brakes each time I replaced each part.
And I did bench bleed the master cylinder.
when I bled the back brakes I took a look they have all new hardware , new drums and new shoes , so I know that isnt the problem.
 
You need to adjust the master cylinder to the brake booster. When you buy a Master Cylinder they don't come pre adjusted. You need at least a 1/6th " between the brake booster pin and the clutch master piston. This provides the right amount of play so that when you push down on the brake the master cylinder can release fully. If the little rod is out too far it will push the piston in and the brake won't release, causing the brake to drag. Loose is better then tight in this case. You need a little free play on the brake peddle but, as long as no one has adjusted the peddle you should be OK.

Good Luck
