    I had a guy tell me that was on my 90 burb. But I don't even know where to start looking. I know my brakes have always felt soft. even after a new booster, master and 3/4 ton axles.

    follow the rear line down the frame rail right side and just before the line goes in to hose bracket for rear axle. there will be a roundish box thingy with a set of arms on it to the axle. the more the axle moves from weight on it the more it opens up the valve if it works correctly.

    just bypass this unit and remove it and throw it out as thay just dont work great and after all these years fill full of sludge. then blead breaks and test drive.
