I am having the same problem and so far what I've been able to find out is that's it's probably a faulty speed sensor. Also been told it could be a bad wire connection at the wheel or a wheel bearing. For now I went ahead and pulled the fuse (it's under the hood) and that stopped the ABS from kicking in....it DOES NOT affect the braking .... the only thing you'll notice is that your ABS and parking brake warning lights on the consol come on. hope that helps in the mean time. Please post if you find the real solution...thanks Susi

I have a 96 Blazer 4x4, everytime i push down on the brake pedal, i have to apply a ridiculous amount of pressure and they still won't work until 3 seconds goes by.

If your brakes feel spongy when you step on the brake pedal then you may have air in your brake lines.

ABS AND BRAKE LIGHT by mcg24

I HAVE A 2001 GMC JIMMY 4X4 THE BRAKE LIGHT AND THE ABS LIGHT COMES ON SOMETIMES. WHEN THE LIGHTS ARE ON I HAVE NO PROBLEM WITH THE BRAKES AT ALL THE VEHICLE STOPS LIKE NORMAL. I CHECKED THE FLUID IT FULL. I'M THINKING IT MAY BE A ABS SENSOR GOING OUT OR I KNOW IN SOME VEHICLE THESE LIGHT COMES ON WHEN THE SPEED SENSOR GOES OUT. CAN THIS BE CHECKED WITH THE LIGHTS NOT BEING ON ALL THE TIME.

I have a 1998 Jimmy and the Flasher is Constantly Sounding. With your Problem did it Stop Sounding when you put on the Brakes? Turn Signals and Hazards Work Fine, Noise Driving me Nuts.

I have a 2001 Jimmy 4x4 also... The ABS light went on and off when ever it wanted to...be very careful when the light is on my brakes just lock up when pushed really hard. The ABS part did not work when the light was on. I crashed the Jimmy two weeks ago. I hit ice and when I tried to use the brakes they just locked up they did not pulse and make that funny noise they make when the abs kicks in.

I had the same problem and replaced the abs unit that I picked from the junk yard. This did help but I still get that groaning noice. I tried to clean the sensor myself but it was pretty rusted. I think I will try this next. Thanks

ABS and Radio by harvm

My 2001 Tahoe LE has brake and ABS dash lights on. Gotta get the thing state (TX) inspected asap. Also, radio speakers quit speaking. Are the two problems, ABS and speakers, related?

Had the same issue sort of, found a service bulletin from Chevy ... there is a plate on the wheel hub between the sensor and the hub, rust builds up under the plate and raises the sensor too high .... I disassembled, removed the sensor, scraped out the rust (becareful to not get loose rust in the hub) and the problem disappeared...
