2004 Chevrolet Monte Carlo Brake Proportioning Valve Parts and Q&A

• Q: How to replace the Brake Proportioning Valve on 2004 Chevrolet Monte Carlo?

  A: Washing the proportioning valve is forbidden because its internal components arrive with specific grease already in place. Start the repair by removing both the bracket from the master cylinder followed by the master cylinder reservoir. Use needle nose pliers to remove proportioning valve caps together with O-rings , springs , and proportioning valve pistons while making sure to protect the piston stems. Check the pistons for signs of corrosion and deformation before changing any damaged parts. Use clean denatured alcohol to sanitize all pieces then use non-lubricated compressed air for drying. When replacing the components use the silicone grease from the repair kit to lubricate the O-rings together with proportioning valve seals and proportioning valve piston stems. Install the new proportioning valve piston seals by positioning the lip seals upward and install the components into the master cylinder body. Position the springs inside the master cylinder body while placing new O-rings in the proportioning valve cap grooves. Tighten the proportioning valve caps to 27 Nm (20 ft. lbs.) torque specification.Replace the bracket to both the master cylinder and the master cylinder reservoir afterward. Finally, bleed the brakes.
