Air Brake Wheel Speed Sensor problems of the 2000 GMC Sierra

Abs brake system is causing truck to feel like it's not going to stop. I have it at the dealership now and they tell me both sensors have to be replaced. I only have approx. 22,000 miles on the truck. It's a 2000 Sierra.

Antilock brakes engage at low speed, like when coming up to a stop sign, or when pulling up to a drive thru window.

Vehicle: 2000 GMC Sierra, ext. Cab, 4wd, less than 19000 miles. Vehicle exibited intermittant low-speed antilock brake activation. Although there were many "close calls" especially when the antilock motor would activate upon initial brake application (very low pressure in hydraulic lines), no damage was caused to the vehicle or other property. A potential dangerous situation exists with these heavy vehicles. Low output from right front abs sensor was diagnosed. I replaced entire hub and sensor assembly. The symptom is now gone. The old part is still in my posession for inspection.

I have a 2000 GMC Sierra extended cab 4x4 z71. I believe I have the same problem with my abs sensor as has been reported by others. I have not had an accident but I have had many close calls. I pulled the fuse for my abs and now I do not have the problem, but am afraid my brakes will lock up in foul weather.

Antilock brake problems on my 2000 GMC Sierra pickup. Hard to stop vehicle at at low speeds [under ten miles per hour. ].

Brakes fail below 5-8 mph.

Anti-lock brakes chatter and fail to stop on my 2000 GMC Sierra pickup truck at anything under 10mph. This started last October. The dealership quoted $480 to correct. Saved a bunch of money by unplugging the fuse for the abs sytem. Stops fine now. I almost hit the back of my garage wall and stopped cars in front.

Failure of the abs system on my 2000 GMC Sierra pickup. Abs would acctivate at slow speeds and would make stopping truck very hard. Had to DE activate abs system so truch was useable. Dealer stated that problem was due to region of country that the truck was used in and was not their problem!.
