Wabco air brake parts for trucks and trailers
Wabco makes air brake, air suspension and trailer control systems for trucks and trailers, and it is one of the brands Truckstop Group distributes nationally. The Wabco parts we stock are concentrated on air braking.
Brake chambers and actuators are the biggest group, including type 16 and type 24 chambers for cam and disc brakes spring brake actuators such as the 30/30, and Tristop cylinders. Valves include trailer control valves and 3/2 directional control valves. For air supply, there are an E-Air processing unit for Scania and an air processing unit for Mercedes, and steel air reservoirs including a 40 litre tank. Trailer connection parts include the 24V ABS/EBS 7-pin socket, with fittings, plugs and silencers alongside.
The Wabco part number is the reliable reference for every one of these. Other brands are in truck brake chambers and truck air brakes.
Frequently asked questions
How do I find the right Wabco part?
Read the Wabco part number from the label or casting on the part you are replacing. Wabco numbers are ten digits, and the full number matters, as variants differ by the last digits. If it is missing, call us on 01527 68279 with the vehicle or trailer details and a description of the part.
Do you stock Wabco air processing units?
Yes, including an E-Air processing unit for Scania and an air processing unit for Mercedes. Match the Wabco or OE part number before ordering, as units differ by vehicle and system.
What does a trailer control valve do?
It controls the trailer's brakes from the tractor unit, passing the brake signal from the tractor's system to the trailer and applying the trailer brakes if the supply line is lost. Replace it with the same Wabco part number.
Do Wabco electronic components need calibration after fitting?
Some do, depending on the system. Check the vehicle or trailer maker's procedure for the part you are replacing, which may require a diagnostic tool after fitting.
