Once installed, the brake pad shims operate passively as part of your vehicle's braking system. Their primary function is to dampen vibrations and reduce noise. No specific user operation is required for the shims themselves. However, proper break-in procedures for new brake pads should be followed as recommended by the brake pad manufacturer to ensure optimal performance of the entire braking system.
