Control
1. The switch is located at the top of the brake pedal.
Fig. 15.1 Typical brake light switch installation diagram
2. Disconnect the switch connector.
3. Check the continuity between the contacts using an ohmmeter. When the switch plunger is pressed, there should be no continuity; when it is not pressed, there is continuity. If the switch does not function as described, replace it.
Replacement
4. Disconnect the electrical connector if it has not already been disconnected.
5. Loosen the switch lock nut (see fig. 15.1) and remove it from the bracket.
6. Installation is carried out in the reverse order of removal
Adjustment
7. Loosen the switch lock nut on the switch side and move it until the plunger is fully pressed by the pedal pusher.
8. Move the switch back half a turn and tighten the lock nut.
9. Check the operation of the switch: when you press the pedal, the brake light should light, but not when the pedal is released.
