Some vehicles may experience misadjusted brake light and cruise control switches as a result of applying high pull loads to the service brake pedal. If this condition is encountered, it can be corrected by replacing the original pushrod/retainer assembly with a new pushrod/ nylon retainer assembly, P/N 18011412 using the following procedure:

See Illustration

1. Remove the brake light and cruise control switches.

2. Pull rearward on the brake pedal to remove the pushrod from the Powermaster unit.

3. Loosen the Powermaster unit from the front of dash by removing the two nuts that secure it to the mounting bracket.

4. Pull the Powermaster unit forward. Do not disconnect hydraulic lines. Support Powermaster unit to prevent damage to unit or hydraulic lines.

5. Visually inspect the pushrod socket and remove any particles left from the original rubber retainer (see Illustration). Denatured alcohol can be used to clean socket.

6. Disconnect the original pushrod, retainer, and boot from the brake pedal. Discard the pushrod and retainer. Do not discard the boot.

7. Insert the new pushrod/nylon retainer assembly into the boot and install the boot onto the bracket.

8. Attach the new pushrod/retainer assembly to the brake pedal.

9. Pull the brake pedal rearward as far as it will go and block it from moving forward.

10. Reinstall the Powermaster unit to the bracket (nut torque should be 20-34Nm or 15 to 25 Lb.Ft.)

11. Install the pushrod in the Powermaster unit by inserting the push-rod into the socket and carefully applying up to 100 lbs. load to the service brake pedal.
