Dodge Colt/Challenger/Conquest/Vista 1971-1989 Repair Guide

Brake Warning Light Switch


The warning light switch is unrepairable, and must be replaced as a unit if problems occur. The switch may be located in the combination valve, in the master cylinder reservoir or mounted in line between the master cylinder and combination/proportioning valve. Replacement is made by disconnecting the brake lines or unscrewing the switch. If the switch is located in line, the brake system will have to be bled after replacement.
