Brake light and rear antilock lights on
Noticed while driving my 1990 F150, the rear antilock light, and brake light are on at same time. Truck has good firm brake pedal, brakes working great. What could be the problem??

Brake fluid level is low, or the float in the reservoir is stuck at the bottom - first thing to check.

does the parking brake pedal return all the way up? There's a switch on that too. That could cause the brake light but shouldn't cause the ABS light. That truck only has rear ABS, the sensor is on top of the rear axle gear housing. I've seen them come off.

I can check the park brake pedal to see if it is all the way up
