The contact owns a 1998 GMC Sierra 1500. While approaching a stop between 1-5 mph, the brakes vibrated, made a hissing sound, and lunged forward. The mechanic diagnosed a failure with the service brakes, hydraulic: antilock. The contact's vehicle year was not included in NHTSA campaign id number 05v379000 (service brakes, hydraulic). The contact filed a complaint with GMC on March 10, 2008 and was issued confirmation number 71-1609860847. The purchase date was unknown. The current mileage was 111,500 and failure mileage was 111,000.
While driving consumer stepped on brake pedal to stop or reduce speed, instead, it resulted in extended stopping distance. Also, front brakes prematurely wore out, and had to be replaced at 18000 miles.
Since I have owned this vehicle, the antilock brakes seem to engage for no reason on dry pavement. When this happens, you have the feeling that you will not be able to stop. This started after is was out of warranty so the dealer has not looked at this problem. My son is a GMC certified mechanic, and we have investigated this problem and been unable to determine it's cause. I understand that this is a common problem with this make and model of truck, however I can find no detailed reports on this. Please advise as to whether you are aware of any problems concerning the braking systems on the GMC and it's sister vehicle the chevy. Thanks, steve varley.
