4502011 Piston, Brake Caliper Pin

The 4502011 piston serves as a critical component within the air disc brake caliper system, ensuring precise pressure and reliable deceleration. Designed to meet the rigorous demands of heavy commercial vehicle braking systems, this high-strength component maintains structural integrity under high-pressure operating conditions.

This piston with a diameter of Ø 58 mm is engineered for compatibility with several major heavy-duty brands. It is a suitable replacement for models in the VOLVO FH series (including FH12, FH13, FH16), VOLVO FM series (FM10, FM11, FM12, FM13), and RENAULT TRUCKS (Magnum, Premium, Kerax) as well as MACK (Pinnacle, Granite) and DAF. 4502011 is the OE equivalent of the specific braking components used in these heavy-duty truck and tractor units.

For workshop technicians, maintaining the brake caliper assembly involves regular inspection of the piston and pin surfaces. Ensuring the Ø 58 mm diameter component is free from debris and operates smoothly within the caliper housing is essential for preventing system drag or uneven braking forces. Regular maintenance intervals help prevent premature wear in heavy-duty applications.

Always verify compatibility with specific engine types such as D13C, D12D, or DXi series to ensure an exact fit during service.
