Brake Switch (Cruise Control): Adjustments

IMPORTANT:
^ Do not adjust the TCC.ABS (1) or the stoplamp/BTSI (2) switches until you have connected the brake booster push rod to the brake pedal assembly.
^ Adjust the TCC.ABS (1) and the stoplamp/BTSI (2) switches together.
^ Incorrect adjustment of any of these components may cause the cruise control system to work improperly.
^ For more information about the stoplamp switch replacement, refer to Stoplamp Switch Replacement in Brakes.
^ DO NOT depress the brake pedal during the following adjustment procedure.

NOTE: Proper stoplamp switch adjustment is essential. Improper stoplamp switch adjustment could cause brake drag and excessive brake lining wear.

1. Insert the release switch (1) into the retainer (3) until the switch is fully seated against the brake pedal arm.
2. Twist the switch (1) in order to lock the switch into position.
3. Measure the distance from the end of the barrel on the switch to the pedal arm. Ensure that the clearance is 1.5-1.7 mm (1/16 in). If the measurement is incorrect, perform steps 1 and 2 again.
4. Ensure that the following components close at 3.5-12.5 mm (1/8-1/2 in) of brake pedal travel:
^ The contacts on the release switch assembly (1)
^ The contacts on the stoplamp switch assembly (2)
Measure this travel at the centerline of the brake pedal assembly pad. The nominal actuation of the stoplamp switch assembly contacts is about 4.5 mm (3/16 in).
