The Function Of Shims

When it comes to brake pads, shims play an essential role in ensuring optimal performance and longevity. Shims are thin pieces of material, usually made of metal or rubber, that are placed between the brake pads and the brake calipers. These small but mighty components serve multiple important functions, including reducing noise and vibration and preventing corrosion. Let’s explore each of these functions in more detail.

Reducing Noise And Vibration

One of the key benefits of using shims in brake pads is their ability to effectively reduce noise and vibration during braking. As the brake pads come into contact with the brake rotors, they can create friction, leading to irritating squeaks, squeals, or rattles. Shims act as a buffer between the brake pads and the calipers, absorbing these vibrations and minimizing noise.

How do shims achieve this? By acting as a dampening material, shims absorb the high-frequency vibrations that occur when the brake pads make contact with the rotors. This absorption process transforms the vibrating energy into heat, reducing the noise that would otherwise reach your ears. So, not only do shims keep your braking experience peaceful, but they also contribute to a quieter and more enjoyable ride overall.

Preventing Corrosion

Another crucial function of shims is their ability to prevent corrosion. When brake pads are exposed to moisture, such as rain or road spray, they are more prone to rusting. Over time, this corrosion can compromise the performance of the brake system, leading to reduced braking efficiency and potential safety hazards.

By placing shims between the brake pads and the calipers, a protective barrier is formed. Shims provide an extra layer of defense against moisture, preventing it from reaching the brake pads directly. This helps to minimize the chances of rust formation and extends the lifespan of both the brake pads and the calipers.

Moreover, some shims are specifically designed to have anti-corrosive properties. These shims are often coated with materials like rubber or silicone that offer enhanced resistance to rust and corrosion. By using such shims, you can further safeguard your brake system from the damaging effects of moisture and ensure its longevity.
