Are you trying to lock your brakes up?? If so then something might be wrong with your front- lines, calipers, pads, rotors, porp valve. Or maybe your backs are set too close. If not than probably something in the porp valve

Got air in the lines?

Rear Brake Lockup

Take a look at the proportioning valve. I had the same problem. Replaced the valve with a new one, and 20 minutes later I was all set....
Good Luck! Cameron

Is there any evidence of gear oil on the rear brakes? Sometimes the rear seals leak, allowing gear oil from the differential to get onto the brakes. This will cause them to lock up easily. Must replace the axle seals and replace the shoes.
