Volvo Coupes/Sedans/Wagons 1970-1989 Repair Guide

Brake Light Switch



See Figure 1

The switch controlling the brake lights is located at the brake pedal. As the pedal moves from its rest position, the switch engages and turns on the brake lights. To change the switch, simply unplug the connectors at the switch, unscrew the locknut and remove the switch.

After installing the new switch, it must be adjusted so that the switch engages (brake lights come on) after 3 / 8 - 1 / 2 in. (9-12mm) of pedal travel. With the brake pedal in the released position, the distance (A) between the brass hub of the switch and the pedal lever should be 0.08-0.24 in. (2-6mm). To adjust, loosen the attaching screws for the switch bracket and move the switch in the required direction.
