What Are Brake Shims?
Brake shims are small, thin pieces of material that are designed to provide a precise fit between the brake pad and the brake caliper. They are typically made from a durable, wear-resistant material such as steel or ceramic and are precision-cut to ensure a snug fit. Brake shims serve several purposes, including:
- Providing a precise fit between the brake pad and the brake caliper
- Compensating for minor imperfections in the brake pad or caliper
- Preventing excessive wear on the brake pad or caliper
- Ensuring proper alignment and clearance of the brake pad
Why Are Brake Shims Necessary?
Brake shims are necessary for several reasons:
Without brake shims, the brake pad and caliper may not fit together properly, leading to:
- Reduced braking performance
- Increased wear on the brake pad and caliper
- Potential for brake failure
