High-quality rubber material: Made of high-temperature resistant rubber material, it has excellent elasticity and sealing, effectively preventing mud, water and dust from entering the brake system, and extending the service life of components.Precise dustproof and waterproof: Designed specifically for disc brake lower pumps, it fits tightly to the caliper and shock absorber parts to form a double protective barrier to prevent internal precision parts from corrosion or blockage and causing brake failure.Strong versatility: It is suitable for disc brake systems of various motorcycles and electric vehicles. It is easy to install without modification. The 5-point fixed design is stable and does not fall off. It is compatible with most mainstream brake pump models.Wear-resistant structure: The special corrugated or pleated design adapts to the frequent movement of the brake pump piston, is not easy to tear, and can still maintain flexibility and protective effects after long-term use.Improve safety: Reduce the interference of external impurities on the brake oil circuit, ensure sensitive brake response, avoid safety hazards caused by jamming or oil leakage, and ride more safely.Package:10 pcs Motorcycle shock absorber dust cover
