When it happened on my 95 Lumina Van it was the rear brake cylinder, a $4.00 part. The car couldn't be driven according to the mechanic, so it cost me $100.00 to have replaced.
if you mean the brake light on the dash... fill your brake fluid as it's probably low If you mean the brake lights outside the car, your switch is shorted and needs replacement, or you need to lift your foot off the pedal
switch off
you reset your car. It should be in the trunk.
Top off the brake fluid resorvoir.
Could be a bad or misaligned stop light switch at the upper end of the brake pedal under dash area
brake fluid
The brake light in your dash comes on , if the brake fluid level in the brake master cylinder in your engine compartment is LOW , and also if your emergency brake is on
You need to find and fix the problem. Either your emergency brake is not completely off or you have a problem in your cars brake system. That warning light is there to warn you that a serious problem exists.
The red " BRAKE " light in your dash comes on if the parking brake / emergency brake is on and also if the BRAKE FLUID LEVEL in the brake master cylinder located in your engine compartment is LOW
THE BRAKE LIGHT IS LOCATED BELOW THE DASH. LOCATE THE ARM HOLDING THE BRAKE PEDAL AND YOU WILL SEE A SWITCH THAT COMES OUT WHEN THE PEDAL IS DEPRESSED TURNING THE LIGHT ON. WHEN THE BRAKE IS RELEASED THE SWITCH DEPRESSES AGAIN TURNING THE LIGHT OFF.
The brake light switch is under the dash, and whenever the brake pedal is touched the brake light comes on. If the switch has failed or is out of adjustment it will leave the brake light on.
I have a 2000 sienna..........and had that light come on......in has to do with the braking system
