Brake Disc problems of the 1999 Chevrolet Malibu - part 2

Due to the excessive wear of the brake rotors and pads, when traveling and upon depressing the brake pedal to make a normal stop, consumer noticed a griding sound coming from the front end. Also, there was vibration within the steering column. Consumer has contacted the dealer, dealer has replaced brake rotors and pads. Problem still occurs. Please provide any further details.

Front end vibration. Consumer took vehicle to dealer, they replaced the rotors and front brakes. However, problem recurred.

Brake pads would wear out excessively when brakes were in use. Had them replaced once before. Would make grinding noises against the rotors. This hampered vehicle from stopping, causing steering to shake.

When applying brakes at highway speeds over 50mph steering wheel vibrates. Dlr has changed brakes 3 times, and problem still occurs.

This vehicle had both front disc pads replaced at 9,500 miles. The disk brake rotors on both sides were replaced at 10,500 miles. At 14,900 both front calipers, brake pads, and disk rotors will be replaced again. It steering shakes violently upon braking above 30 mph, any brake actuation malkes multiple noices that indicate obvious disk brake stress failure, both front wheels exhibts great quantities of burned in brake dust. This problem has been also experienced by two friends who have similar vehicles. It is obvious there is a serious, life \ safety manufacturing defect in the disk brake system. Gm dealership has replaced parts without question or argument (which should immediately alert you to the fact that they are well aware of a widespread problem). There is no recall on this vehicle for this. Mentioning the problem to the local dealship mechanics and service personnel produces an immediate, no-argumentative recognition that the problem and system failures obviously exist and are well known (to them). In fact, one mentioned they were saving the parts taken off the 99 Malibu's for a gm enginner who was coming to inspect them. This is an extrememly serious life safety issue that has not been publicised and owners have simply be given replacement parts, only to have to replace them again and again. Brakes are the first line of safety and this cars disk brakes in the front are simply unreliable. It may be that the juneau, alaska very humid environment is part of the problem. No matter, gm is dragging this out for whatever purpose. The problem is obvious.

Rotors have been replace twice and machined twice in 40,000 km. Brake pads have been replace 2 or 3 times. Was told by the dealer and gm canada that if you drive the vehicle in the rain the rotors will warp. Rotors serviced @ 10,000km 20,000 km 26,000 km and 40,000 km. Tried to charge me while the vehicle was still under warranty for machining the rotors. Had to complain loudly to get them covered would not cover pads. Still trying to get some satifaction from gm canada. Dealer would not admit there was a problem with the vehicles until the consultant called back and wanted to ensure he would not get a bad rating on gm warranty service questionaire. Then all of a sudden they have had some problems with the brakes/rotors on these vehicles.
