5. Principi operativi
The disc brake caliper is a vital part of your vehicle's hydraulic braking system. When the brake pedal is pressed, hydraulic pressure forces the caliper's pistons to move, clamping the brake pads against the rotating brake rotor. This friction converts kinetic energy into heat, slowing down the wheel and, consequently, the vehicle.

- Dual-seal: Designed to avoid brake fluid leakage and ensure excellent braking capacity.
- Copertura antipolvere: Prolongs the service life of the product by preventing dust and debris from entering the piston area.
6. Manutenzione e cura
Regular inspection and proper maintenance are essential to ensure the longevity and optimal performance of your brake caliper assembly.
6.1 Anti-Rust Coating
