How to Change brake switch

Jennifer, just making sure that we are talking about the external brake lights and the brake light switch that is located on the top part of your brake pedal. Try to adjust it first.

Disconnect the brake pedal position switch connector, loosen the brake pedal position switch locknut (A), and back off the brake pedal position switch (B) until it is no longer touching the brake pedal.

Turn up the carpet. At the insulator cutout, measure the pedal height (C) from the middle of the left side of the pedal pad (D).

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.

Screw in the brake pedal position switch until its plunger is fully depressed (threaded end (A) touching the pad (B) on the pedal arm). Then back off the switch 3/4 turn to make 0.9 mm (0.04 in.) of clearance between the threaded end and pad. Tighten the locknut firmly.

Connect the brake pedal position switch connector. Make sure that the brake lights go off when the pedal is released.

Check the brake pedal free play as described below.

Pedal Free Play

With the engine off, check 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 in.)

If the pedal free play is out of specification, adjust the brake pedal position switch (C). If the pedal free play is insufficient, it may result in brake drag.

If you do need to change it follow these instructions:"

REMOVAL & INSTALLATION

Detach the brake light switch electrical connector.

Loosen the locknut.

Remove the brake light switch by unthreading it in a counter-clockwise direction.

To install:

Thread the brake light switch into its mounting bracket until the threaded end of the switch contacts the pad on the brake pedal. The switch plunger should be fully depressed and not visible at this time.

Back off the switch 1 / 4 turn to allow 0.01 in (0.3mm) of clearance between the threaded portion of the switch and the pedal pad.

Attach the brake light switch electrical connector.

Connect the negative battery cable.
