Abs comes on at low speed.. It increases stopping distance.. I have once rear ended a vehicle because of this. There was no damage to either vehicle.. Also my ABS light come on for a few seconds maybe two or three times a month..

During an emergency stop on highway from approx. 45mph, due a tractor trailer suddenly stopping, ABS brake system started to fluctuate, but truck did not stop normally. Avoided collision by veering to side of road. Left front brake line, at clip near wheel, leaked brake fluid thereby preventing quick stop. Brake pedal went to floor afterwards, there was seemed to be no secondary hydraulic system pressure for rear brakes. Emergency brake was hardly effective.turns out all brake lines are severely corroded in nearly all areas, even under hood. Truck has 50,000 miles and is 6 years old. Have also previously experienced sudden power steering failure due to power steering line corrosion and fluid loss. Power steering system provides hydraulic boost for brakes, therefore brakes are impacted also. Brake and power steering lines seem to be made of steel with incorrect or poor alloys, thereby acting like a sacrificial anode on the truck, as evidenced by the rust throughout the lines, vs. Localized rust. Brake lines and power steering lines have been replaced. Still have several rusty lines for inspection if needed.

I was heading north bound on I-45 near north avenue in milwaukee, wi when it began to rain slightly. It was approximately 3:28 am. I slowed down to 50 the speed limit was 55 and the I turned on my fog lights to help me see better by the time I got to capital drive it was a complete downpour. Raining very hard. I was in the very inside lane ie: "the fastlane" I was approaching the hampton avenue exit and there was a semi on my right his rear tandom axles where just to the right of my passenger side front tire and he was coming over to my lane. I hit the breaks and was steering to the right to go towards the middle lane. My brakes locked up and the ABS brakes never turned on. This is a 2003 gmc 2500 hd crew cab all the weight is in the front an the cab. When I hit the brakes I was heading for the right lane and the truck turned 90deg to the left and hit the concrete divider wall. At full 50 MPH speed and the passenger rear came around and hit the wall as well. The air bag never deployed. I hit the wall with so much force that the bed of the truck embedded in the rear of the cab. Mind you this was a 3/4 ton truck it takes a lot of force to have this happen. I feel that if my ABS breaks have pulsated 10 times per second per wheel I would have came to a controlled stop on the right shoulder of the road with the trajectory I was heading. The air bags never deployed. Good thing I was wearing my seat belt. The time of the crash was. 3:45 am.
