Brake Noise Is It Normal?

Brake friction materials generate noise and heat in order to dissipate energy, a necessary physical reaction. When this occurs, brake dust and vibration of the brake pad within the caliper is generated. These factors can be changed by other environmental and road conditions such as ambient temperature, moisture, road salt, mud, etc.

It is important to remember that all brakes make noise. The frequency at which the noise becomes audible to us will vary. Any effort to eliminate an intermittent brake noise, which is considered normal, is usually temporary at best.

This is not to say, however, that all brake noises should arbitrarily be considered normal. Brake noise should be diagnosed as outlined in the appropriate model year service manual.
