Compatibility and Installation:

Confirm the full number on the existing assembly, the vehicle identification number (VIN), and the brake-system configuration before purchase. A reference-number match does not establish compatibility with every vehicle. Programming, calibration, installation requirements, and supplied accessories must be confirmed for the specific application. Installation should be performed by a qualified technician following the vehicle manufacturer's service procedures.

The photos are Parts Finder Q reference images from the existing 4008518760 listing in the same catalog family. They illustrate the related reference-number assembly. Confirm the exact supplied unit label, condition, reservoir, and hardware before ordering.

Frequently Asked Questions:

What is WABCO 4008518767, and where is it installed?
It is a hydraulic ABS assembly with an electronic control unit (ECU), in WABCO's Hydraulic Compact Unit (HCU) product group. In the WABCO Hydraulic Power Brake (HPB) system, the HCU mounts to the vehicle's frame rail and generates hydraulic service-brake pressure. This is a hydraulic brake-system component, not a universal air-brake ABS module.

Which International trucks are listed for this part?
Wheeler Fleet's application catalog lists International 4300 (2008–2016) and International 4400 (2009–2016) for this part number. These are distributor-listed applications, not confirmation for every truck in those ranges. Verify the VIN, complete original assembly number, and hydraulic brake configuration. An unlisted model year is neither confirmed compatible nor ruled out by this list.

Which Ford trucks are listed for this part?
The same distributor catalog lists Ford F-650 Super Duty and F-750 Super Duty (2009–2015). Model and year alone are insufficient: the original part number, brake-system configuration, and vehicle-specific ECU requirements must also match.

Will 4008518767 fit a Freightliner, Mack, or Volvo truck?
Catalog cross-references include Freightliner TDA S400 851 876 7, plus Mack and Volvo references in WABCO's replacement list. A brand cross-reference does not identify a verified truck model or year. We have not confirmed a model-year application list for these brands, so do not order on the brand name alone. Check the VIN and original unit label with the vehicle manufacturer or a qualified parts specialist.

Is S4008518767 the same reference, and how do I check a replacement?
WABCO lists Meritor S4008518767 among the references replaced by 4008518767. That catalog relationship is a starting point, not a guarantee for every installation. Use the VIN and complete original assembly number to verify the approved replacement configuration, including connections, mounting, hydraulics, and required ECU calibration. A similar appearance or a related number on its own is insufficient.

Does installation require programming or brake bleeding?
Do not assume the replacement is plug-and-play or preprogrammed for your truck. ZF/WABCO's HPB maintenance manual requires vehicle-specific OEM/VIN parameters when replacing the ECU or ECU/HCU assembly. Parameters must not be copied from a different vehicle. HCU replacement also requires the specified brake-circuit bleeding, leak checks, and functional checks. A qualified commercial-vehicle brake technician should follow the current OEM and WABCO service procedures.
