1990 antilock brake
 

my dash antilock brake lite stays on the brakes work fine and the brake lights work cant find any reason for the dash lite to stay on is there a sensor? if so where would it be?thxs

The sensor is located on top of the rear differential housing

I had my light come on also. I Added a little bit of brake fluid and the light went off. Check the level and possibly add a little bit.

Brakes are getting low. Happened on my ranger, changed brakes, lights went out.
