Features: This is a useful tool, disc brake pad spacer. Easy to adjust space between rotor and pad of disc brake caliper. By reasonably filling or supporting, stabilize the position of the brake disc to avoid abnormal contact between the disc and the brake disc caused by slight shaking during braking. Compact in size and light weight in structure, it can be installed without the need for professional tools. Simply place the adjusting plate in the corresponding position according to the actual clearance situation to quickly adjust the brake clearance. While adjusting the clearance, it does not affect the braking effect of the brake, ensuring that the disc can be properly attached during braking and providing stable braking force.
