4017015 Plate, Brake Caliper Pad Plate — WABCO

The technical function of this plate is to provide structural stability within the brake caliper assembly, ensuring precise engagement of the pads during braking operations. As a critical component in the air disc brake system, it is engineered to withstand high thermal and mechanical stress in heavy-duty environments.

4017015 is the OE-equivalent of the WABCO 640 225 926 2 Brake Caliper Pad Plate used in WABCO MAXX 22 T and PAN 22 SINGLE systems. This part is also compatible with SCHMITZ CARGOBULL (1146640 - R) and HENDRICKSON (S-35303-9 - R) hardware, ensuring seamless integration within professional braking architectures.

Workshop technicians should ensure that the direction of installation matches the specific requirements of the vehicle, as this component is designated for the Right (R) side. Regular inspection of the caliper pad plate during routine brake maintenance is recommended to prevent system degradation. This part maintains high-strength performance under demanding service intervals.

Maintenance of the braking system requires precise assembly to ensure safety. When replacing components, always verify that all OEM codes such as 640 225 926 2 or S-35303-9 - R are correctly matched to prevent mechanical interference in the air disc brake caliper assembly.
