Check your tires for belt shift and clean the inside of the rims for dirt buildup.

ABS/Parking Brake?Service Engine Lights are on But Runs Great


Does ABS work properly? Get on dirt road and try to lock brakes (do this carefully insuring no police car tailgating,lol) Could be bad wheel speed sensor. Check codes with scan tool capable of reading ABS and trans codes.

My 1997 Chevy Blazer ABS light comes on and then shuts off but does it regularly. Also it makes a noise on the front brakes when using them. What could be the problem?


One of the wheel speed sensors is going bad probably. If the brake is shuddering when pressed like when the ABS kicks in then the sensor is bad.

I am having trouble with the abs braking system on a 1998 chevy blazer. The yellow brake light is usually off for the first few minutes of driving and then comes on and stays on until the car is turned...


the yellow light is warning you that a problem exsists with the abs. unless you are experienced with brakes and abs would highly suggest you take it to a shop.

ABS works poorly


You can try unpluging the fuse under the hood for the ABS but your brake light and ABS light on the dash will come on.I'm in NH and it would fail the saftey inspection if either of thoughs lights were on during the inspection.See if this helps your problem but you most likely have a wheel sensor going bad in the ABS system.

My 1995 honda preludes emergency brake doenst work, when you pull it up it comes up easy and the break light does come on, also my ABS light is on and wont turn off


The parking brake problem could be rear brakes out of adjustment, a broken parking brake cable, or a parking brake cable in need of adjustment.

The ABS light mosy likely has nothing to do with your parking brake problem and will have to be diagnosed by first gathering the ABS fault codes from the ABS computer.

Look under the hood where the ABS unit sits.(on drivers side)

Make sure the engine is NOT Running and the key is OFF. Also check that the parking brake is Not Engaged at this time.

First unplug the two wire connector on the ABS unit. IIRC the wire colors for this connector are Red and Black, and they are of a fairly thick gauge.

The ABS/Brake light will remain on at this time if you start the motor, so skip that and look for a second connector on the ABS unit. This one has multiple wires and are much thinner gauge than the first connector. **Unplug this connector. With key OFF, pump the brake pedal 10-15 times. Start the motor and there should be no ABS or Brake lights illuminated on the dash.

You just completely eliminated the ABS Unit from your braking system and will only have NON- ABS power brakes from now on. The ABS unit will only act as an extended brake fluid reservoir and will not influence braking an any way...you will have to pump the brakes yourself if needed.

On my personal vehicle...also a '94 S10, I went one step further and fabricated an ABS pump elimination kit that allowed me to physically remove the entire unit and tie the lines back into the system using a simple valve found on many domestic master cylinders. I may fab up some kits if there is any interest, but it's really not needed...I'm just anal about my vehicles.

**NOTE: Some GM ABS units have two additional plugs besides the two wire connector, if so just unplug them both.

1999 Chevy Blazer ABS Light and Parking Brake Light


You will need to find out which speed sensor has gone bad. Only way to know it to hook it up to a scan tool. The burning smell is possibly a caliper sticking as these vehicles are bad about them sticking after brake pad replacement.
