Do motorcycle brake pads need shims?
You might be wondering whether your motorcycle requires brake pad shims. These small metal components can enhance your motorcycle’s safety, help the braking system function more effectively, and reduce noise. Similar vibration control principles are also applied in shock absorber systems. Not all brake pads require shims, so please verify your specific motorcycle model first. Motorcycle brake pad shims are distinct from suspension shims—such as MAX Shock Shims—which are designed for use within the suspension system. Understanding this distinction will help you select the appropriate parts for your bike. Key Takeaways What Are Motorcycle Brake Pads Shims? Purpose and Function You may be wondering about the function of motorcycle brake pad shims. These thin metal or rubber plates are installed between the brake pads and the calipers. They help enhance braking performance and extend the service life of the braking system. The table below outlines their primary functions: Function Description Noise Reduction Rubber gaskets reduce noise and vibration, resulting in a more comfortable riding experience. Alignment Shims help align the brake pads with the brake discs, thereby achieving optimal results. Heat Shielding They keep brake pistons from getting too hot, which keeps you safer. Improved Braking Performance Shims help the brake pads make better contact with the brake discs, thereby enhancing braking performance. Reduced Wear and Tear They prevent uneven wear of brake components, thereby extending their service life. How Shims Reduce Noise and Vibration Occasionally, a piercing squeal can be heard when applying the brakes. This sound typically originates from vibrations occurring between the brake pads and the brake discs. Motorcycle brake pad shims act as a barrier, effectively absorbing these vibrations. Studies have shown that shims help eliminate the oscillations responsible for brake noise. In suspension systems, similar control is achieved through precision shock shims.
