Retarders
Functioning as a secondary braking system, retarders provide added safety and economy.
We developed retarders as part of our ongoing pursuit of enhanced driving safety. As retarders are noncontact and create no wear, they are ideal auxiliary instruments to improved braking performance.

TBK started manufacturing retarders in the 1960s. Today, buses, trucks, and other heavy-duty vehicles are equipped with our retarders. Drawing on our accumulated technological expertise, we developed our current range of retarders, which operate electromagnetically.

Outstanding characteristics of TBK's retarders
Safety and comfort
TBK's retarders work to directly control and slow down the drive shaft, thus reducing brake load and minimizing the risk of brake fade. Retarders become more effective when used with cruise control systems. Thanks to retarders, drivers do not need to brake frequently, and thus enjoy better driving comfort. @
Economy
Retarders' deceleration function helps extend the lives of drum brakes, linings, rotors, and pads, making maintenance more cost-effective.
Potential
Because TBK's retarders are electromagnetic, there is no time lag and they are compatible with ABS. As stricter regulations over exhaust emissions are expected, retarders may replace exhaust brakes in the future. Meanwhile, more and more heavy-duty vehicles will be equipped with disc brakes, further boosting demand for retarders as auxiliary brakes.
Mountability
Mounted directly to the drive shaft, our retarders require no engine modifications. Operating friction-free, they also need no maintenance. In addition, they are air-cooled, and require no cooling devices.
NEW
Regeneration-type Retarder
Electromagnetic retarder that requires no power supply and can regenerate during deceleration.
