I had the same problem - it has to do with your front hub. Probably best to take into the dealership

Hi. My girlfriend has the veh. and problem.. Me being a mechanic.. I checked all abs sensors and cleaned them of brake dust. I had found that there is a recall on this problem..What it is hyundai had put the abs ans traction control together,and if the tires start to spin the abs kicks in and helps get traction..Here is the problem.. when the brakes pads get wet there is alittle slip of rotor and pad which causes the light to come on,also when applying the brake at low speeds...What I had done was get the best rotors and pads,and that is helping

I ve got a kalos 1.4sx 2008 and i ve got problems with the brakes. The brakes ''crunch'' when i m bringing the car to a halt,even on dry roads. The abs warning light has been on a couple of times but...


The Chevrolet/GM autos rely on a Kelsey ABS actuator system that is electronically controlled. I know its hard to describe sounds, but is it possible the crunch is a hum? If the ABS light comes on and goes off after restart it means one of two things. That the ABS controller is going bad or the speed sensors on the wheels have come loose or gone bad. Under your hood there is a fuse compartment that contains the fuse that controls the ABS system on your vehicle. Its a 60 Amp fuse and large.. Look in your owners manual for its location. . Check it with the vehicle OFF to make sure its not blown or cracked. Leave the fuse disconnected and start the car. The ABS light should STAY on as well as the parking brake light. Test your brakes by pressing down on them while the car is in park and not moving.. do you hear the sound. If you DONT hear the sound then the ABS control module is causing the brake pump to work continuously and thus your "noise". YOu can confirm by placing the fuse back in place and then listening to the car about where the drivers door is... do you hear a hum? If so you can leave the fuse disconnected to deactivate the ABS module. The brakes will still function you just WONT have ABS capability. Confirm this with a very slow roll from park or neutral and press brakes to stop. If you dont hear the noise or a hum, reconnect the fuse and take the car for a drive. Turn to the left and right while applying the brake at an intersection.. vehicle in motion slightly. Do you notice that the ABS light or noise occurs turning one way or the other or both? If it comes on during the turn then the ABS sensor in that wheel or both wheels need to be inspected and possibly replaced. Finally, you need to inspect the brake pads for wear..typically however brake pads have WEAR INDICATORS built in and will start to SQUEAL when you apply the brakes telling you time to replace pads. If its a squeal and not a crunch then have pads replaced. Finally, be sure and make sure you dont have any rocks or road debris within the brake area or between teh pads and the rotors. That would be your final area to review for a CRUNCH noise.

Try bleading the brakes, sounds like you have in them. Than the ABS light should go out & you shouldn't have to worry about the fuses.

Fixing brakes


you have a abs fault considering the year I of the van I would remove abs fuse or unplug the moduale to disaable it. the humming that you are hearing is the abs dumping pressure due to a false reading from one of the sensors or the moduale if you want to spend the money to make the abs work you will have to take it to a shop and have them hook up a computer to retreive the codes to diagnois the problem. keep in mind that with the abs dissabled the wheels will lock up when braking hard or slick roads let me know how you make out

Run Away ABS


There is no one answer or cure all for this problem, you need to have the ABS system tested for fault codes and then the technician can give you an informed idea of what the problem might be and some idea of the cost to repair it
