What steps should be followed for replacing the Brake Proportioning Valve on GMC C3500?

Before replacing it, take note of the code marked on the old valve for the right replacement. Start by taking out the combination valve's electrical connector, proceed with removing the front brake lines and then continue with the rear brake lines. In the next step, take out the three alien bolts (11) securing the combination valve (12) to the bpmv and get rid of the combination valve (12) and the two transfer tubes (13). Be certain that transfer lines (13) are new when you replace the combination valve and that the replacement code punched into the part is the same as the one in the old combination valve. Attach the two transfer tubes (13) to the combination valve until they are seated, after which you should put the combination valve (12) onto the bpmv. Install the three combination valve bolts (11) and tighten them at first only to 8 nm (6 ft. Lbs.), then to 16 nm (12 ft. Lbs.). Cover the front and rear brake pipes with the combination valve, tighten each of the brake pipe fittings to 24 nm (18 ft. Lbs.) and then connect the combination valve to the electrical connector. A final step is to ensure the combination valve metering rod is pushed in as you start bleeding and then proceed with the brake bleeding.
