Brake Shims: Don’t Judge A Book By Its Cover

A quality brake shim can prevent brake noise during the entire life of the brake job and will not dry out or be displaced over time like some lubricants or pastes. But, remember, a shim cannot do its job if it remains in the box.

Brake Shims: How To Control Brake Noise

Brake shims are not designed for adjusting spacing and distance between friction material and the rotor. Shims provide multifunction noise control as a component attached to the friction pad backing plate. A quality brake shim can prevent brake noise during the entire life of the brake job and will not dry out or be displaced over time like some lubricants. But remember, a shim does not do its job if it is left in the box.

Brake NVH: Real World Applications

First know that all brakes make noise. When the friction material makes contact with the rotor, the coupling causes the brake pad and rotor to oscillate and vibrate. The components are locked as a combined system that will ­vibrate at the combined system’s natural frequency of vibration. This is called force-coupled excitation. The driver hears
