SOURCE: abs and hand brake light

Check your master cylinder switch in the res. is not stuck down. When started is the light off until you go over 15 mph? If so check your abs relay. Good luck

SOURCE: Abs/Brake Light ON, although new brakes, ABS still works

I would suspect a speed sensor.

SOURCE: abs light is on? 2004 chevy avalanche

what i've seen with the k series chevrolet trucks is that the wheel speed sensors develop corrosion where the sensor mounts to the hub. you can start by taking the sensor out and cleaning off the mounting surface with a wire brush. the process is:

1. raise front of vehicle onto jackstands
2. remove front wheels
3. remove the brake caliper, bracket and rotor on both sides
4. remove wheel speed sensor via 1 torx bolt (be carefull as the corrosion will cause the sensor to "stick" in the hole)
5. clean the mating surfaces with a wire brush so the sensor bolt hole and mounting surface on the hub is shiney again.
6. if you can, pick up a can of rust preventing primer and spray a little on the surfaces to prevent further corrosion
7. let paint dry
8. apply a thin fil, of grease to the sensor and the sensor mounting spot on the hub
9. re-install sensor
10. revers steps 3-1 for re-installation.

*process is the same for both sides.

this was a common problem on the k series trucks.

while your in there it wouldn't be a bad idea to check the sensors wires to make sure they arent broken. let me know if the repair works for you

SOURCE: 2002 chevrolet avalanche how do you know when

If you have a bad booster you would have a really hard pedal and it would take two feet to stop. Sounds more like a fluid leak or a bad master cylinder. Are you adding fluid or do you have a red brake light on?

SOURCE: 2007 Chevrolet Uplander LT ABS and TC light on

We were having this problem...have your wheel bearing checked out. There was a sensor in the drivers side wheel bearing...once we replaced it (because it was going out) the ABS and Traction Control warning lights stopped coming on.

There are wheel sensors at each wheel that look for current when the wheels spin, if one fails then the ABS light comes on.

Whats wrong my abs light is on, my brake light is on and my speedometer nor odometer are working? 2004 jeep grand cherokee larado 6 cyl 4.0 liter

here is the short version...

the vehicle speed sensor is actual an interpreted signal from the ABS module and the ABS module uses the wheel speed sensors

therefore, if the ABS module sees a problem with any sensor it will affect the PCM input for vehicle speed

another possibility, but worst case, is the ABS module has failed

in either case you will need a professional scan tool to monitor actual wheel speed versus PCM vehicle speed

Abs skipping

If you can test the car without the ABS module to ensure that the ABS is not the cause of the problem, If you have a spare module you can have it replaced for a while to test if the module is faulty,
