  1. Clean any dirt, gravel, and other foreign material from the base of the brake pedal, the plunger boot, and the brake base bracket.
  2. Use light oil to lubricate the brake pedal roller and pivot pin.
  3. Check the brake plunger boot for cracks, holes, or deterioration. Replace it if necessary.
  4. Lift the edge of the brake plunger boot and check the plunger for existing lubrication.
    1. If the plunger is dry, remove it by removing the brake pedal and brake plunger boot. Lubricate the plunger and the inside surface of the boot with barium grease (p/n BW 246671) or Pennzoil Adhezoplex EP2. Install the plunger, boot, and the brake pedal.

      Important: Use only these approved lubricants.

      1. If the plunger has grease on it, lift the edge of the brake plunger boot enough to apply 2 to 4 drops of light oil around the brake plunger, where it slides into the brake base bracket. Install the plunger boot around the brake base bracket.
