Air Brake Diagnostics

As commercial vehicles evolve the complexity of the electronic system grows, In the past it was possible to diagnose most faults with limited equipment such as a multi-meter whereas the latest systems now require laptop software with appropriate equipment.

We at Devon Fleet Components have fully trained technicians that are proud to be able to offer this diagnostic service for all makes of trailers and most makes of trucks

We can offer fault diagnosis for the following:


(Antilock Braking System)


(Electronic Braking System)


(Electronically Controlled Air Suspension)

Some of the later vehicles have an electronic air dryer fitted called an (EAC) this is a dryer which needs resetting each time the cartridge is changed and in the event of the unit failing a new unit needs to be programmed with the old parameters to make it compatible in order for the vehicle to be able to start and we are also able to offer this service.

Commercial vehicle braking systems are safety critical and should not be compromised by fitting non-genuine substandard equipment at Devon Fleet Components we only distribute and fit parts manufactured by Knorr-Bremse , Wabco and Haldex which gives you a nationwide fully backed warranty.




In the event of an earlier system failing and spares not being available we can also offer to retro-fit a new ABS/EBS system please ask for details.
