4506011 Volvo Compatible Brake Caliper Pin Piston

What does a brake caliper pin piston do?

This brake caliper pin piston is a critical component within the air disc brake caliper assembly. It facilitates the movement of the caliper pins, ensuring consistent pressure application against the brake pads. Built with high-strength components, it is designed to withstand the intense thermal and mechanical stress found in heavy commercial vehicle braking systems.

Vehicle and system compatibility

This specific part is compatible with Volvo vehicles and Meritor systems. It is engineered to meet the rigorous demands of heavy-duty braking applications, ensuring precise piston movement and system stability. The component features a diameter of Ø 68 / 63 mm for accurate fitment.

Installation and maintenance

During installation, technicians should ensure that all surfaces are clean and that the piston is seated correctly within the caliper pin housing. Regular inspection of the pin piston is recommended to prevent uneven brake wear or sticking, which can compromise braking performance in heavy commercial vehicles.

Troubleshooting guidance

If you notice uneven pad wear or vibrations during braking, it may indicate a need to replace this component. Always verify compatibility with your specific vehicle model before installation to ensure optimal system performance.
