4056013 WABCO Brake Caliper Piston

The heavy-duty grade piston is a critical component within the brake caliper mechanism, ensuring precise pressure application and consistent braking performance. Designed to withstand demanding operating environments, this part maintains structural integrity under high thermal and mechanical stress, providing essential reliability for heavy commercial vehicle braking systems.

4056013 is the OE equivalent of the WABCO PAN 19 DOUBLE and PAN 22 DOUBLE piston used in the WABCO braking systems. This component is engineered to meet strict technical specifications to ensure seamless integration into existing air disc brake-related assemblies, maintaining safety and responsiveness during vehicle operation.

For workshop technicians, this piston is designed for efficient assembly within the brake caliper mechanism. Regular inspection of the piston and surrounding seals is recommended to ensure optimal braking force and to prevent system degradation. It is vital to verify compatibility with the specific WABCO system models before installation to ensure a perfect fit and optimal service life.

This specialized part is manufactured with high-strength components to guarantee long-term durability in the field. By maintaining precise tolerances, it supports the overall stability of the air disc brake system, reducing the risk of unexpected downtime during heavy-duty transport operations.
