Brake lights on, but brakes are fine...

[whitetail97]

Truck is a 97 Ranger 4.0 4x4... My abs and ebrake lights are continuously on...The brakes work fine though. No leaks, reservoir is full. What should i check? I have heard that the rear sensor attached to the diff often picks up junk from the diff and goes bad...I am about to check that. Any other ideas what to check out? Thanks!

Can't remember the name for it, but there is a part that goes to the abs/brake light. It is mounted on the frame. Don't know if in same location on your model, but mine was on frame on driver side almost right directly below the brake booster. These lights were on, on my 91 and that part was the culprit.
