Three problems related to brake abs warning light have been reported for the 1997 Ford Expedition. The most recently reported issues are listed below.
Initially, while applying the brakes on dry pavement, the abs would engage intermittently. The front brakes were replaced after this happened. Unfortunately, it continued to occur intermittently. After which, the abs light would light up. The rear abs sensor was replaced and it still continued to happen, but the brake pedal would be hard initially but could be pushed through. A bearing was replaced on the frontend. The abs would continue to engage randomly. Now, after the vehicle has been driven, then sat for 15-30 minutes, and then driven again, the abs will engage--but then the brake pedal is very hard and difficult to push. The abs light comes on. Our mechanic is now using his "tech hotline" to learn how to fix this.
When pushing on the brake pedal it took an extra twenty feet to stop. It felt like it was on ice. The dealer inspected the brakes and found no defects, and the computer showed nothing. The brakes would get hard and the calipers were clicking. When the vehicle had gone over bumps, the abs light would appear on the dash. The vehicle would be turned off and back on and the light would go off.
Abs brake problems; the abs waring light stays on. Dealer not able to detect prolbem with system. When applying the brakes, they squeak and lock up.
