  Q: How to replace the front brake proportioning valve on GMC Savana 3500?

  A:

  Note down the identification code of the valve before ordering a replacement unit. Place safety stands to support the vehicle after it raises to a suitable height. First remove the retaining bolts from the shield before removing the shield from the vehicle. Attach the combination valve by disconnecting both the 2-way electrical connector alongside brake pipes front and rear. Disconnect the allen bolts from the bpmv to combination valve connection and then remove the combination valve. The new transfer tubes should be completely seated within the valve before you install it to the bpmv. Mount the allen bolts to anchor the combination valve while using an 8 nm torque setting (6 ft. Lbs.) before moving to 16 nm (12 ft. Lbs.). Apply torque of 8 nm to the first stage (6 ft. Lbs.) and increase it to 16 nm for the second stage (12 ft. Lbs.). Connect front and rear brake pipes to combination valve through fittings while applying 30 nm of torque force (22 ft. Lbs.).drill new transfer tubes into the valve before you reattach this to the bpmv. Complete the reconnection of the 2-way electrical connector. Attach the shield to its location by screwing in the retaining bolts until they reach a torque of 12 nm (8 ft. Lbs.). Begin brake hydraulic system bleeding after you depress the metering rod of the combination valve and proceed with the bleeding process.
