Retarder Control Units

Bus retarder control units – optimum control of the braking system

In this section of the Peterbus.pl online shop, we present specialist electronic components responsible for the correct operation of auxiliary braking systems in commercial vehicles. Here you will find original, used retarder control units (retarders), which are a key element of the safety system in touring, intercity and urban buses.

These modules are responsible for the precise, proportional management of hydrodynamic or electromagnetic braking force. The retarder control unit works closely with ABS/EBS systems and the vehicle's main control computer via the CAN bus. A properly functioning control unit ensures effective and smooth deceleration, directly reducing the load on the service brakes, extending the service life of brake discs and pads, and protecting the braking system against overheating during long downhill drives.

Safety and precision: selecting retarder control units by factory numbers

Control electronics for retarders require absolute precision when selecting replacement parts. Our range includes retarder control units from renowned manufacturers supplying original-equipment solutions for the bus industry, including WABCO, Voith, Telma and ZF.

When replacing a damaged component, it is essential to match the new part precisely using serial numbers and type markings, such as the DIGIPROP series. Every module in our range undergoes detailed verification of its catalogue markings and visual condition, allowing the correct selection of a unit fully compatible with your vehicle's software and network architecture.
