Brake Light Switch: Adjustments
BRAKE PEDAL AND BRAKE SWITCH ADJUSTMENTPedal Height
1. Disconnect the brake switch connector, loosen the brake switch locknut (A), and back off the brake switch (B) until it is no longer touching the brake pedal.
2. Pull back the carpet. At the insulator cutout, measure the pedal height (C) from the middle of the left side center of the pedal pad (D).
Standard Pedal Height (with carpet removed): 169 mm (6 10/16 inch)
3. Loosen the pushrod locknut (A), and screw the pushrod in or out with pliers until the standard pedal height from the floor is reached. After adjustment, tighten the locknut firmly. Do not adjust the pedal height with the pushrod depressed.
4. Screw in the brake switch until its plunger is fully depressed (threaded end (A) touching the pad (B) on the pedal arm). Then back off the switch 1/4 turn to make 0.3 mm (0.01 inch) of clearance between the threaded end and pad. Tighten the locknut firmly. Connect the brake switch connector. Make sure that the brake lights go off when the pedal is released.
5. Check the brake pedal free play as described below.
Pedal Free Play
1. With the engine off, inspect the pedal free play (A) on the pedal pad (B) by pushing the pedal by hand.
Free Play: 1-5 mm (1/16 - 3/16 inch)
2. If the pedal free play is out of specification, adjust the brake switch (C). If the pedal free play is insufficient, it may result in brake drag.
