WABCO Truck Braking & Air System Parts

WABCO is a specialist brand for commercial vehicle braking, air management and stability systems within the wider ZF group. Its valves, air dryers, compressors, brake control modules and ABS/EBS electronics are fitted as original equipment on many modern European trucks, trailers and buses, where safety and uptime are critical for fleet operators.

On this WABCO brand page at VRA Truckparts you will mainly find used OEM WABCO components removed from late-generation DAF, MAN, Volvo, Scania and Mercedes-Benz trucks. Parts are taken from complete donor vehicles, inspected and, where possible, function-checked before we list them for sale. That way you keep genuine WABCO hardware designed to work with factory air brake and electronic control systems, while reducing repair costs compared with brand-new dealer parts.

• Used OEM WABCO air compressors, air dryers and air tanks for heavy truck air brake systems
• Brake chambers, calipers and wheel-end components matched to specific axle and brake setups
• Relay valves, protection valves, foot brake valves and other pneumatic control components
• ABS/ESP and brake pressure sensors, switches and wiring from complete air brake systems
• Stock focused on modern Euro 5–Euro 6 HGVs used in UK and European fleets

You can browse all WABCO truck parts in stock or explore wider categories such as Brakes & Brake Parts and the main Lorry/Truck Parts catalogue, then use filters for brand, truck model and part type.

About WABCO Commercial Vehicle Technologies

WABCO is a long-standing specialist in braking, air suspension and control systems for heavy commercial vehicles. Now part of the ZF commercial vehicle portfolio, the WABCO brand covers advanced brake control, air treatment, stability management and driver assistance technologies designed specifically for trucks, trailers and buses. These systems combine pneumatics, electronics and software to keep vehicles safe, stable and efficient on the road.

Because many European truck manufacturers specify WABCO as original equipment on their air brake and stability systems, replacing a failed part with a genuine WABCO unit helps maintain the truck’s intended performance and compatibility with OEM ECUs and wiring looms.

WABCO Truck Parts We Stock

The WABCO components listed on this brand page come from complete donor trucks dismantled at VRA Truckparts in the UK. Stock changes as we process new vehicles, but most WABCO items are related to air braking, pressure control and wheel-end braking. Typical groups of parts include:

Air Compressors, Air Dryers & Air Tanks

• Engine-driven WABCO air compressors that supply pressure for the truck’s service and parking brakes
• WABCO ECAM and other air dryers and air processing units that remove moisture and manage system pressure
• Brake air tanks and reservoirs used to store compressed air for multi-circuit brake systems

Many of these items can also be found in our dedicated air system categories, including Air Compressors, Air Dryers and Air Tanks, where you can filter by truck brand and other criteria.

Brake Chambers, Calipers & Wheel-End Parts

• Service brake chambers and spring brake actuators for steer, drive and tag axles
• Air disc brake calipers and related mounting hardware used on modern European axles
• Associated brackets, pushrods and fittings where they are integral to the WABCO brake assembly

For a structured view of these components, you can browse Brake Chambers and Brake Calipers, then filter by WABCO brand and your truck model.

Valves, Hoses, Sensors & Electronic Modules

• Relay valves, multi-circuit protection valves, load-sensing valves and foot brake valves
• ABS/ESP wheel speed sensors, brake pressure switches and wear sensors from complete air brake systems
• Air brake hose connectors, lines and fittings that link valves, tanks and chambers on the chassis
• Electronic control units and modulators used in WABCO ABS/EBS and stability systems where available

These WABCO parts often appear in specialist categories such as Brake Sensors & Switches, Brake Hose Connectors, Brake Lines, Hoses & Fittings and Parking Brakes.

Quality, Testing & How We Handle WABCO Parts

All WABCO components on this page are taken from carefully selected donor vehicles dismantled in a controlled environment at VRA Truckparts. Before major parts are removed, we aim to run the truck and confirm basic brake operation and air build-up where this is safe to do. During dismantling, technicians remove WABCO units methodically, checking housings, ports, threads and connectors for obvious damage or heavy corrosion.

• Only genuine WABCO products from complete trucks – no generic copies in this brand section
• Visual inspection of each part for cracked casings, damaged fittings and worn or bent mounting points
• OE numbers and WABCO references recorded wherever visible on the label or casting
• Items that do not meet our standards are rejected before they reach the shelf

Compatibility, OEM Numbers & Choosing the Right WABCO Part

WABCO brake and air system components are often specific to a particular truck model, axle layout, brake size and emissions standard. Even parts that look similar externally can differ in port layout, cracking pressure, internal calibration or software version. For that reason, we always recommend matching the part number on your existing WABCO unit against the references and photos shown in our listings.

For best results when choosing a replacement WABCO part:

• check the full WABCO reference and any OEM numbers printed on your current unit;
• compare threads, ports and mounting points with our product photos;
• use our How to Find the Right Part guide and follow the steps in our Compatibility & VIN Policy when using VIN or registration data.

If you are unsure, contact us with your VIN, clear photos of the existing WABCO part and any visible numbers. Our team will cross-check your information against the donor trucks we have dismantled and the parts available in stock.

Shipping, Warranty & Returns for WABCO Parts

All WABCO components are shipped from our warehouse in Stanford-le-Hope, Essex, using tracked services across the UK and mainland Europe. Many items can be dispatched within one working day once payment is received. Details of carriers, pallet options, typical transit times and how to report transit damage are explained on our Delivery & Shipping page and in the online store checkout.

Used OEM WABCO parts are covered by the same policies as our other components. Before placing a larger order or supplying parts on to your own customers, we suggest reviewing Warranty & Part Condition, Returns & Refunds and, where relevant, Core Units & Surcharge. These pages explain warranty periods, condition grades, how core surcharges work and what to do if there is a problem with a part.
