My antilock brake system stopped working and my emergancy brake light is on even though the brake is down. the fluid is fine.

Have you checked the brake fluid level ?

Have you checked brake fluid level and pad wear

Bad wiring somewhere.. Did you recently install something electronic???

There is a malfunction in you antilock brake/traction control system. When the TRAC light is on, the computer is trying to tell you either 1. That the traction control is active and is controlling your brakes, engine and transmission to stop a wheel skid, or 2. There is is a malfunction in your traction control system.

In the first case above, the TRAC light will only be on for a few seconds until the conditions causing your wheels to slip no longer exist. If the light is staying on even though there is no way your wheels are slipping or skidding, then this is a malfunction. You must scan both your Powertrain Control Module (PCM) and your Antilock Brake System (ABS) module to properly diagnose a problem with this system.

The ABS system is related to emergency stopping, not normal brake use, where you don't want the tires to lock-up when the brakes are hit very hard. ABS stands for Antilock Brake System. When the ABS light is on, the ABS system is not active. This means the ABS will not be Antilock when you need it. This does not mean you don't have brakes. The brakes you have are normal brakes without the added feature of antilock.

The light is on because a system fault has been detected. Most of the time this is a wheel speed sensor that has failed. Basically the system works by having 4 wheel speed sensors connected to a control unit. The control unit determines how much braking presure each wheel needs according to how much pedal presure you are applying, related to the vehicle speed, and the rotation speed of each wheel. If one wheel is spinning slower than the others that would mean it is locking up (less braking efficientcy) and the control unit then reduces the presure applied to that wheel so it doesn't lock up.

If a wheel speed sensor goes bad the entire system can't function so it shuts down and it is now a regular braking system. This means that it will work and feel fine to you, the operator. But in an emergancy, the ABS will not function and the brakes may lock up which is not as efficient as ABS.

I recommend you get it scanned for codes and find out what is wrong. It is a great safty feature that I think you are better off with, than without.

Some auto parts stores will scan your car for codes for free, like autozone and others. Call around and find that free scan. Then take it to a reputable shop, dealer, or your brother-in-law who is a master mechanic.

Good luck, and be safe!

I think it means the Antilock Brake System is disengaged. So, a code has been stored in the abs computer. Standard obd tester cannot check these codes, must visit your dealer or some autoshop with ABS reader.

According with the service manual: During starting the RED brake light should briefly come on and then go off. If the RED light stays on, it indicates a problem in the main braking system, such as a low fluid level, or the parking brake is still on.

Hope helps (remember to rate and comment this).

Depends on car. But pretty much the same for most. The brake light can come on if the fluid is low in the master cylinder. Either from a leak or you need to change brakes. or the emergency brake switch is bad.

Make sure your emergency brake pedal is all the way up, because sometimes if it goes down one notch, that can trigger that light to come on..It wont be enough to drag or slow the sar down, but it will be enough to turn that light on...Also even though your brakes are good..double check your break fluid level...

with an abs light on it means the antilock brake system is disabled and therefore your brakes could lock up in an emergency braking situation other than that your brakes will work normally. the antilock brake system works on signals from tone rings and sensors that sense if any wheel is slipping locking up or losing traction, there is also a brake pressure modulator. you should be able to pull the codes for the abs auto parts stores should be able to do this for you with a code reader most will do this for free, this will tell you where the problem is. hope this helps

This light is an indicator that you have a problem with your braking system. It is not only an emergency brake indicator. The first thing that you should look into is whether you have a low level of brake fluid.

Be careful to not get ANY dirt into the reservoir if you open the lid. If you need to add fluid, please read your owners manual for the right type for your vehicle. Always use new, unopened fluid. Brake fluid absorbs water when exposed to the atmosphere.

Please be aware that a fluid loss could indicate a problem in your brake system, and you should try to determine what is causing the loss.
