Four problems related to brake electric antilock have been reported for the 1998 Chevrolet K3500. The most recently reported issues are listed below.
When driving at any speed and applying the brakes, the abs system isn't working and not stopping the vehicle, but the horse trail that is attached to the vehicle is stopping the vehicle.
Vehicle in shop 8-10 times for poor braking performance. Steering not working. Suspension fails & it pulls severly to left. Dealer/mechanic test drove vehicle w/owner. Could not repair pulling to left, suspension or steering problems. Is a commercial vehicle.
While slowing down from high speed 55mph+, the brake system takes very long time to bring vehicle to a stop. In heavy rainfall, the problem tends to be exaggerated even worse. Even at very slow speed 5-10 mph, when brakes applied the brakes would lock up, causing on or both of the rear wheels to lock and skid. Pedal will then vibrate or shake as in experienced with an abs system under full-braking conditions.
When applying the abs brakes on dry pavement at 20 mph the brakes did not grab, but the pedal nearly traveled to the floor, causing extended stopping distance. Consumer states during a panic stop, wheel locked up and then there was a total release, several times at 2 second intervals.
