When appling brakes i sometimes hear grinding and ticking noise and abs light is on


A grinding noise is usually an indication that the brake pads are worn out. You may also have a defective wheel bearing causing this noise and in turn can cause the ABS light to come on due to poor sensor contact. Have the brakes and bearings inspected soon to avoid unnecessary costly repairs.

Abs dash light comes on brakes work fine where before there was grinding noise when gently braking?


remember that abs stops the wheels from locking up during harsh braking.now what might have happened is that brake pads were low and finally they went down to the sensor causing the sensor to break off hence the light on . you can get the abs probbed and it may have a code to direct you to the problem.

I was wondering on a alero 99 , i replaced the brakes and a caliper and fixed my brake lines but my abs light is on but it sounds like a airplain when u drive their is no shaking or grinding in the front...


YEP BAD WHEEL BEARING WILL MAKE A ROARING LIKE NOISE WHILE IN MOTION.BAD WHEEL COULD PUT DRAG ON WHEEL WHICH CAUSE ABS LIGHT TO COME ON.YOUR WHEEL BEARING HAS THE WHEEL SPEED SENSOR BUILT INTO IT.SO IF WHEEL BEARING BAD THE WHEEL SPEED SENSOR PART OF ABS BRAKE SYSTEM WILL CAUSE ABS LIGHT TO COME ON IF WHEEL BEARING BAD.MAKE SURE FRONT BRAKE PADS INSTALLED CORRECTLY IF NOT. YOU WILL GET TERRIBLE WHEEL NOISE ALSO.

2007 vw rabbit abs light blinks on a steep grade


abs sensor blinking is usually cause by a bad wheel speed sensor or vehicle speed sensor. not too sure what going up hill is doing. sometimes that can move brake fluid around if its low and will detect low brake fluid, but you brake like would also come on with the abs sensor. check and fill brake fluid to fix that. to fix a sensor you need to bring the sensor readings up on a vw scan tool to see which one is cutting out. should take to vw shop for scan tool. they might charge you .5-1 hour diag time but its better then the hassel and expense of parts replacing. finally if they find nothing wrong with the speed sensors going up hill, then its probably the abs unit. check those in that order and you'll find it.

Abs light has come on (56 For Fiesta, 11k miles!)


Could be a speed sensor, but what I would do is take it over to maybe some one like Autozone where then can do a free code reading.

Traction control light comes on off and on. ABS light also comes on. I have replaced both front hub bearing units and brake pads front and back. Every nmow and then the brake pedal feels grinding or jerky...


Could possibly have a bad connection on a wheel speed sensor. This would cause an erratic reading making the ABS light come on because the system thinks a wheel is either slipping or dragging.

Grinding noise in front end and abs light came on


check wheel bearing play. if the play is excessive it will cause the abs sensor to come away from tone ring loosing signal, illuminating abs light.

Abs sensor light wont go off my 2005 polo


Your ABS systems use a combination of electronic and hydraulic systems to modulate the brakes individually to prevent them from locking up. ANTILOCK systems consist of wheel speed sensors, a hydraulic control unit (HCU), and an electronic control unit (ECU). Because of how complex the system is your computer does a self-test. If the check is successful, the ANTILOCK and BRAKE lights will go out within a few seconds. If one of the component of the ABS system fails to pass one or both lights will remain lit. One or both warning lights may also come on while driving, also indicating a problem. If just the ANTILOCK warning light comes on, some ABS component has failed, but the car still has hydraulic brakes. The grinding noise could the the ABS pump or your brake pads could to worn to the metal backing and grinding against the brake rotors. I recommend a inspection soon for your safety.

ABS Light


I would not ignore this problem. Some damage has been caused to your braking system, i doubt if is is as simple as resetting the abs sensor. You should have the wheels removed and the suspension and braking systems fully checked over either by yourself or a competent mechanic .as the grinding sound could be a symptom of a serious safety hazard.

Driving on a flat could have buckled the rim or damaged the discs, steering or suspension.

ABS Problems


Gary,

Just went through this problem with my Dakota as well. This is a very very very common problem with the Dodges. First things first. Replace the Vehicle Speed Sensor on the rear differential. Cost around 40 dollars at your local auto parts store or even from the stealership. Its easy to change as well one nut and off comes the bracket then the stud comes off and then you can take out the sensor. They big key is here to be VERY careful pulling out the sensor or you will break it off in the housing. You will need to slowly turn and pry it out with a small screwdriver (as there is an Oring holding it in). Reverse the process to install the new one. After you get the sensor in, reset everything by pulling the negative off the battery and leaving it off for 30 min (some require less time but 30 min is safe) to ensure all is reset. Hope this helps you.

Sincerely,

Jeremy
