Emergency brake stays on when fully disengaged

Are you sure it is the tail lights and not the brake lights? If the park lights are staying on, the front should be on as well in most cases. If it is the brake lights staying on, suspect a faulty brake light switch located at the brake pedal

check your brakefluid level

Check your emergency brake. Make sure it isn't partially pressed in. Try unplugging the switch to the emergency brake and see if the light goes out; if it does the switch is bad.

Emergency cable might be sticking and engaged a little to trigger the brake light.

It probably indicates that the cable is not being fully retracted when brake is disengaged. Spray as much of cable as possible with WD-40, allow to sit for a few hours, the engage and disengage the brake several times untill it loosens. If this fails the cable may be stretched and needs to be replaced.

the rewd brake light comes on for two reasons,the E brake in use,or air in the hydraulic brake system,
unhook the E brake switch first,it is connected to the E brake pedal up high,if your light is still on it will be you need to bleed the brakes

Check the brake fluid level.

Either the peddle is not going up fully to meet the switch that turns the light off or the switch may be loose or faulty

you have an ABS code in the ABS computer. You most likely damaged an ABS sensor. even after myouo fix this you will need to get the code cleared
NOTE: autozone wont be able to access the ABS computer.

Hi,

Offhand, the brake light warning on most dashboards would indicate that the hand/emergency brake is engaged. If even when the hand/emergency brake is disengaged or is in normal position and the light is still lit, it could indicate that:

• the brake fluid in the reservoir is below minimum level;
• and possibly the brake shoes/pads need replacement.

Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.
