Two problems related to brake grinding noise have been reported for the 2004 Chevrolet Silverado. The most recently reported issues are listed below.
Noted grinding noise from the passenger side of the vehicle when the brakes were applied on a Friday evening. Notified the dealership ASAP on Monday. Vehicle was serviced on that Tuesday. They found that the rear brakes were grinding and the pads had dug into a rear rotor. They installed new rear rotors and pads as well as the left rear emergency brake shoe. There was no warning to this failure. I believe this to be another case of excessive rear brake wear and premature failure. Customer cost was $557. 62 with vehicle still under warranty. The service mileage was 30,419 miles. See TSB 00-05-23-005b, NHTSA id#618104.
Dt: 2004 chevy silevraldo that has 10,700 miles that is experiencing brake problems. The truck is currently at dealer for repair. The first instance occurred at about 1,000 miles. The issue is at low speeds such as being at an intersection or red light and when brake pressure is applied -it goes all the way to floor. There is an increased stopping distance at low speeds. No sounds or noises when this occurs. This happens under any circumstances such as wet or dry conditions. Occasionaly when turning to the left and applying brake pressure there is a grinding noise but suspects this may be due to the tire. Currently truck is in shop for the second time awaiting inspection of the brakes. The first incident was noted as normal by dealer even though consumer thought this was a safety issue. No repairs were made the first time. Nm.
