  Q: What Preparations Are Essential Before Installing a Brake Booster on Dodge Avenger?

  A:

  Put a NEW dash seal (2) on the booster mounting studs before you fit the power brake booster (1). Attach the power brake booster (3) by guiding the push rod and studs into the dash panel. Please install the power brake booster mounting nuts (4) under the instrument panel and tighten them correctly in sequence to 23 Nm (17 ft. lbs.). Fix some Mopar(R) Lubriplate or an alternate lubricant, onto the brake pedal pin (3) at its contact point with the brake booster input rod (1). Secure the push rod from the brake booster to the pin on the brake pedal and use a fresh retaining clip, but don't reuse the original one. Replace the original stop lamp switch with a NEW one and fit it into the brake bracket, because after installation you may not adjust the switch again. Mount the steering column opening cover (and Air Bag if you have one) onto the instrument panel. When attaching the vacuum hose to the vacuum check valve, make sure not to route it where it could brush against anything it passes. Put the rear brake tubes onto the junction block, secure them with the nuts and tighten the nuts until you reach 17 Nm (150 in. lbs.). Set up the master cylinder and the PCM in their proper spots. Put the battery negative cable back onto its battery post, empty the brake fluid in the master cylinder and check the brakes while driving on the road.

  Q: How to Maintain and Fix a Brake Booster on Dodge Avenger?

  A:

  First, to work on the vacuum brake booster, remove the master cylinder followed by the brake booster. Leaving the check valve in the vacuum hose is important; if it does not work well, you need to replace them at the same time. At installation, attach the vacuum hose to the brake booster nipple and then secure it with a hose clip so that the check valve and the brake booster pipe neither touch nor twist against each other, with the hose marking upwards. After that, install the other part of the hose onto the engine and hold it in place with a hose clip. After that, figure out the clearance needed by measuring B, C and D, then use the equation A = B - C - D to get a result of 0.65-0.85 mm (0.0256-0.0335 inch). The clearance of 0.1-0.3 mm (0.004-0.012 inch) will be achieved when a brake booster negative pressure of 67 kPa (9.7 psi) is applied. If the clearance is outside the standard value range, use the push rod screw to reach your desired measurement.
