brake warning light on 85 5000S

[Joseph Rae]

If it is the brake warning light and not the brake pad indicator light
there are 3 sensors that can go bad and cause this.

Sensor on the brake fluid reservoir
Sensor on the pentosin reservoir
Sensor on the master cylinder

On mine it was the master cylinder sensor

Unplug and drive one at a time to see what one may be causing it.

The idiot light is on in my friend's 85 5000S. The
fluid level is fine. What else can cause this light to
go on?

Thanks,
Ethan
