4506021 Piston, Brake Caliper Pin

This high-strength piston component is engineered to provide precise movement within the brake caliper pin assembly. Designed specifically for heavy commercial vehicle braking systems, it ensures consistent pressure and reliable deceleration under demanding driving conditions. The component is manufactured using heavy-duty grade materials to withstand extreme thermal and mechanical stresses found in air disc brake systems.

4506021 is the OE-equivalent piston used in BREMBO braking systems. This part is critical for maintaining the structural integrity and responsive performance of the brake caliper assembly. It is engineered to meet strict industrial standards for fitment and longevity in professional workshop environments.

Workshop technicians should ensure that the installation of this piston follows standard service protocols for air disc brakes. Given its Ø 60 / 75 mm diameter specification, it is essential to verify compatibility with the existing caliper housing before assembly. Regular inspection of the brake system components is recommended to maintain optimal braking force and prevent premature wear of the caliper pin assembly.
