Four problems related to brake disc caliper have been reported for the 2003 Chevrolet Silverado. The most recently reported issues are listed below.
Was traveling at 45 mph and had to make a hard brake application due to unanticipated vehicle stoppage ahead. When speed declined to about 25 mph there was total brake failure and the brake pedal went to the floor. I thought the antilock system was engaging since the pavement was wet although the brake pedal seemed to go farther down than normal. At this time the multiple brake service warnings came on. Just as I was beginning to veer off the road to avoid rearending the car ahead, it started moving and I was able to avoid hitting it. I drove home about another mile and the brake lines were leaking onto the driveway. The truck was towed to the dealer who replaced all the brake lines and both front brake calipers due to corrosion.
: the contact stated while there was moisture on the brakes, the brakes would not grab properly. The condition worsened while towing any load. The dealership determined the caliper rod corroded due to the vehicle being located in a salt belt state. The dealership replaced the caliper brackets, pads, and rotors. The problem persisted.
Premature rear disc brake failure--2003 Chevrolet Silverado, 31750 miles-rear disc rotors rusted, pitted, flaking. Dealer replaced rotors and discs at my cost. Even though rotors are obviously suffering from weather and salt, dealer insists that the calipers still work, therefore it is not a warranty issue. I contend that the literal disintegration of the rotors caused the rapid wear of the brake pads. When inspected in August of 2005, I was told the pads were at 75% thickness. The truck still has 6 months left on the manuf. Warranty.
The contact stated the left front brake caliper broke while driving. The vehicle was taken to a certified dealer for inspection and repair. The manufacturer was contacted. They have agreed to reimburse the contact a portion of the repair cost.
