7.7 - Adjusting Brake Switch ( )

Two methods here for two models:

1. 89 3.6

The mounting plate for the Brake light switch has elongated holes for adjustment. Fix was therefore easy and took about 5 minutes.

2. 90 4.0

Brake light switch is adjustable. However, the way it works is a bit tricky. The switch is actually 3 microswitches pushed with plastic cam. This cam has an arm which the brake pedal pushes. The arm/cam is actually two pieces of plastic interlocked with some fine teeth. One part holds the cam and the other is pushed by the brake pedal. By sliding these over one another the relative positions can be moved.

To do this, you have to remove cover (click fit). Then insert screwdriver to click it over. This is impossible to describe but it's obvious if you can see it.

Two small studs hold brake switch to pedal box. You can get at the nuts just under the rubber bungs in the pedal box (under hood). It's very easy to remove and make adjustment off the car. However, it's a bitch to get it back in again unless you have the master cylinder out. Also note that the brake pedal has enough force to push teeth over one another. This sort of gives an automatic adjustment. However, it's a right pain in the ass if you let go of pedal and it whacks the adjustment all to the end!
