Accumulator "bulb"

    Part # 18038507 Approx. $60.00-$70.00

Tools needed:

  • Rag
  • Open end wrenches
Procedure

Step 1

    Locate the accumulator "bulb" on the side of the PowerMaster unit. The original style accumulator has a smooth face and requires removal by using a thin open end wrench on the base of the bulb. The replacement/upgraded style bulb has a yellow warning label printed on the face in a circular fashion and has a cast in hex "nut" on the face . Note which style you have.

Step 2

    With the KEY OFF, pump the brakes 15-20 times to totally depressurize the system.

Step 3

    Wrap the rag around the base of the bulb, being careful to shield the fender liner and ESPECIALLY any painted areas. If a small drop of brake fluid can seriously cloud and ruin a nice paint job.

Step 4

    Now loosen and unscrew the bulb. The rag should catch any stray drips.

Step 5

    Lightly lubricate the O ring on the new accumulator bulb with a drop of brake fluid and then screw on the new accumulator bulb.

Step 6

    Turn theKEY ON and allow the system to repressurize and check for leaks.
