dash break light
ive done several searches for my question but havent found an answer. My red break light, next to the break sensor light on my dash will not shut off (yes the parking break is not on). it started last week while driving in rain. its on in the morning until my car is up to about 80c temp and will stay on for the rest of the day. i thought maybe something got wet because of the rain but its been doing the same thing during both wet and dry days. any ideas?

In some models that warning light is also used by the master cylinder fluid level sensor and the brake pad thickness sensors.

red light is fluid level in the master cylinder...the yellow is the pad sensors..in both the W116 and W123 models I have.

Check brake fluid level first.
If that's good, check to make sure that the return spring on the parking brake pedal is pulling it all the way up to engage the switch.

Floppy parking brake pedal is by far the most common cause of this light staying on. It does on our 83, mine is firm and good though.
