Brake Noise

Stocklook · December 8, 2005

We got some Ice on the roads today, and my Brakes started making noise, I was driving slow for a long time, and they did put something on the roads. so I was thinking this was why??

I've only got 22k on her 04 Silverado LS ECSB I shouldn't have to replace the front pads "already?"

My 90 GMC went 40k and my 02 Silverado was at 38k with no signs

Could you be a little more descriptive? "Making noise" doesn't tell me anything.

Duh, Sorry,

Ringing like the Brake sensor when your pads need changing,

Would you say this fits?

Model and Year: ALL PASSENGER CARS AND LIGHT DUTY TRUCKS WITH DISK BRAKES

The disc brake system used on vehicles today was designed and developed to meet many different but very strict requirements while providing an optimum level of performance under a wide range of vehicle operating conditions. The design criteria includes government requirements, service life, space limitations, noise level, heat transfer and cooling, stopping ability, pedal effort and feel, fade resistance and environmental effects.

The choice of brake pads is ultimately a balanced choice, but priority must be given to those criteria which affect braking performance under the Federal Motor Vehicle Safety Standards. As a result, a certain amount of brake noise can result. The brake pads used on today's vehicle may cause an occasional and intermittent high-pitched squeak or squeal when brakes are applied with light or moderate pressure. If the brake system is functioning correctly and it is the judgement of the dealership's service department that the demonstrated condition is normal brake noise, the customer should be assured that this is an operating characteristic of disc brakes and no repair should be attempted.

Efforts to eliminate completely the occasional and intermittent noises that are judged to be normal are frequently temporary. All brake noises should not arbitrarily be considered normal however. They should be diagnosed as outlined in the appropriate model year service manual. An example of a similar noise requiring corrective action is the constant high-pitched squeal that is emitted by the disc brake wear warning sensor when brake pads are excessively worn.
