  Q: How to Maintain and Fix a Brake Proportioning Valve on Chrysler PT Cruiser?

  A:

  Always check the service precautions before starting to work on or repair the brake proportioning/combination valve. First, hold the brake pedal down after depressing it by its first inch using the brake pedal holder, so brake fluid won't leak out. It is easier to access the lower left rear proportioning valve if you first take off the air cleaner cover and the hose to the Throttle Body. Take the brake tube away from the specialized valve that needs removing and then take out that valve from the master cylinder by unscrewing it. Applying grease to the O-ring and then inserting it into the port on the master cylinder, tighten it by 40 Nm (30 ft. lbs.). Slide the brake tube onto the proportioning valve and use a torque wrench to tighten the tube nut until you reach 17 Nm (145 inch lbs.). Once the filter cover and air duct are taken off, return and install them. Take away the brake pedal holder, drain the faulty Brake Line by bleeding it and test the brakes by running a short road test.

  Q: How to Service and Repair a Brake Proportioning Valve on Chrysler PT Cruiser?

  A:

  To service or repair the brake proportioning valve, first depress the brake pedal using a brake pedal holder at the brake pedal's first inch (25 mm), then hold the pedal in that place so the master cylinder does not send pressure to the brake hydraulic system and no brake fluid drains from the reservoir. An easier way to reach the lower (left rear) proportioning valve is to take out the air cleaner cover and Throttle Body hose. Unplug the brake tube at the proportional valve that you are going to remove, then remove the proportioning valve attached to the master cylinder. Apply grease to the O-ring on the proportioning valve and if it's not new, remove and replace it. Insert the proportioning valve (1 or 3) into its master cylinder (2) connector, then tighten it to 27 Nm (20 ft. lbs.). Quickly rejoin the brake tube (4 or 5) to the proportioning valve and tighten the connection nut to 17 Nm (145 inch lbs.) Once you remove the brake pedal holder, empty any leftover brake fluid by bleeding the affected line and test the brakes on the road.
