Question

please tell me how to fix it!

thanks so much! hope it works!

Answer 1

Some How or other the switch is Sticking. Use either Graphite Powder or a Penetrating oil such as W-D 40. This can be Purchased at an Auto Parts Store. The Switch is Located on the Firewall where the Brake arm Hits it.

Answer 2

There are a few possibilities:
1) Your brake pedal doesn't have enough "free play", meaning that it's constantly touching the brake light switch (or the switch itself may be sticking);
2) Your parking brake is on, slightly, even though the indicator light might not be on; or
3) Your caliper piston(s)/wheel cylinders are binding, causing them to be constantly applying your brakes. (If so, you would feel a drag on the wheel that is locking that wasn't there before your problem started.)

There are a couple more, but the easiest way to solve the problem would be to take your car into a reputable shop to have a complete brake inspection done. You have a serious problem that should be looked at by a knowledgeable mechanic.

Answer 3

its possible that the switch that turns on the brake lights (usually near the brake pedal) needs adjustment-the brake pedal could be hitting the switch all the time not just when you are braking. otherwise its an electrical short in the switch or the wiring somewhere between the lights themselves and the switch. good luck!

Answer 4

The brake light switch, located on the brake pedal is broken, easy to fix.

Here is just one place you can buy a new one online, any auto parts store will have one.
