Brake failure warning comes on to service brake system. abs and brake light show on dash. and brakes pulse when applied like abs is activated. pads and fluid are good.

The warning lights will stay on until the problem with the stability control and anti lock braking system is addressed and rectified.

If the warning lights are still showing there is still a problem with the system such as faulty wheel sensors.

Check the level of your brake fluid or your brake pads may be worn down and time to have them checked out.

I am not familiar with your ABS as to how it is fed to the brakes but I am pretty sure I know what you are talking about. It sounds like your ABS is activating which is in my case the wheel hub. You will notice a wire harness coming down to your wheels and where that attaches is usually where the problem is. (problem being if I am correct when you brake you are getting a rapid pulsing rather than a smooth brake)

Sometimes if your rear sensors are in the brake backing plates, you will get debris from the Emergency brake pads and this will affect the sensor count. As the wheel revolution is perceived to be different from one rear wheel to the other, the Traction Control system automatically activates and applies the brakes to make the wheel revolution match on both back wheels.

The Emergency brake linings can fall off of the shoes and create this problem. The brake pads in the front can also separate from the front discs and make the ABS warning illuminate.

Best have a Brake shop remove the rear brakes as they can be a pain to get off when the Emergency brake linings grind up.

Possibly a defective ABS sensor, or low brake fluid. Recommend a reputable mechanic to assess the issue.

ABS LIGHT AND MODULE TROUBLESHOOTING:

These details will help.

the car is telling you that it needs new brake pads.if the light was on all the time then your abs would need work..get new pads asap.

sounds to me like the abs relay is bad maybe $75 repair at the dealer
