  2. NOTICE: Do not service the brake pedal or brake booster without first removing the brake light switch. This switch must be removed with the brake pedal in the rest position.

The switch plunger must be compressed so that the switch can rotate out of the bracket. Attempting to remove the switch with the plunger extended (while the pedal is depressed) will damage the switch.

Install these switches with the booster pushrod attached to the brake pedal and with the brake pedal in the rest position. Installing these switches with the brake pedal in any other position will result in incorrect adjustment and may damage the switches.

    To install, reverse the removal procedure.
