About a year ago I installed a full OME lift kit (new rear leafs, shackles, 882's, etc.). Likewise, I made a Brake Prop. Valve bracket to adjust my BPV about 2.5" up. However, I am experiencing "lock-up" in the rear when I have to slam on the brakes in traffic. My questions are:

1) Should I simply adjust my bracket? If so, up or down?
2) Is this common?

Thanks ya'll! I really appreciate your advice.

You need to adjust it down. You made the bracket for 2.5" but you might have only got 2"

Check and make sure your axle seals are not leaking. I couldn't tell mine where and it was doing the same thing. Gear oil makes the shoes expand. If it is replace the leaky seal and shoes.

I had an axle seal go out and shoot gear oil all over the inside of my drum and wheel, never replaced the shoes.......whoops. Anyways, aren't you spuposed to extend the bpv exactly how much lift you have?

That will do it, I have that happen before also. I replaced the axle seal and not the shoes. About a week later it was locking up on me. And yes you should extend the the bpv to your lift.

1) Check the shoes to make sure they arent the problem.
2) Check the BPV by lowering the bracket in 1/2" increments to see if the lock-up condition goes away (try this in an empty parking lot). You can also adjust the actuating rod some to fine tune the valve, either by bending the rod a little, or by tightening or loosening the nut on one end.

To lower the bracket in 1/2" increments just slot the mounting holes on the top.

Thanks! This sounds like great advice. I know something is definetly wrong because the entire ass of the truck gets tail happy when I stomp on the brakes.
