Brake light on dash

The brake light on the dash of my '92 wrangler is coming on sometimes when I slow down. The brakes seem fine, and the fluid is clear and full. What could be causing this? Thanks, Dave

It doesn't seem to have anything to do with the e-brake switch,, from what I can tell by moving it around, but I'll check more closely.

My brake light used to come on and stay on periodically. That problem went away after the dealership fixed the e-brake recall issue.

the causes of a brake light could be a brake fluid float malfunction, but jeeps dont have these

or a pressure differential switch malfunction, but jeeps dont have these

or a brake pad wear indicator, but jeeps dont have these

(noticing a trend here? hehe)

so that leaves one of two things:
1. the park brake switch is either being closed inadvertantly, or its malfunctioning
2. theres a short in the wiring somewhere

probably the best way to start diagnosing would be to cable tie your ebrake the whole way in the up position so it cant move, if this doesnt solve the problem, then its gotta be a bunk switch or a wiring problem. if it does solve the problem, then you simply have to adjust your park brake cables

g'luck

The brake light is directly connected to a switch on the parking brake foot lever. Try pulling the lever up, this should disengauge the switch. If not, check the condition of the switch itself.

I had the same problem and it went away after the dealership replaced the emergency brake assembly on the recall work. Beware! The fuel pump ground wire attaches to the emergency brake assembly. The dealership failed to secure the ground and my Jeep would die.
