What steel is used in brake pads?

Brake pads do not typically contain steel as their primary material. However, steel can be present in certain types of brake pads as a component of the brake pad backing plate or shims. These steel components provide structural support and help dissipate heat generated during braking.

The backing plate is a metal plate located behind the friction material of the brake pad. It serves as a foundation and helps to distribute braking forces evenly. The backing plate is often made of steel due to its strength, durability, and ability to withstand high temperatures.

Shims, which are thin layers placed between the brake pad and the brake caliper, can also contain steel. Shims help dampen vibrations and noise generated during braking. They provide a cushioning effect and contribute to a quieter and smoother braking experience.

It's important to note that the primary friction material of the brake pad, which comes into direct contact with the brake rotor, is typically composed of non-metallic materials such as organic compounds, semi-metallic materials, or ceramic compounds. These materials provide the necessary friction and braking performance while minimizing wear on the rotor.

When selecting brake pads, it's crucial to consider the overall composition and performance characteristics of the brake pads, including the backing plate material, friction material, and any additional components. Always refer to the manufacturer's specifications and recommendations for the specific make and model of your vehicle.
