The roller brake tester FRU-4 is used to make a reliable evaluation of the condition of the braking system of a vehicle, light or heavy up to 20 tn per axle.

Its main task is to carry out a quick and efficient verification of the operation status of the braking control, accurately measuring the maximum braking on the front and rear axles, hand brake, as well as the existing ovality in the discs and drums of the braking system.

The two frames, one for each wheel on the same axle, are mechanically welded steel structures. Their design and the most demanding production and quality processes, give our machines robustness, reliability and longevity.

Rollers are mounted inside the frames to ensure adequate adherence for successful testing. Their powerful motors drive the rollers and the force cells report the braking measurement continuously during the test.

A computer controls the entire measuring system and the operation of the machine. The control can be done by keyboard, mouse or remote control and the visualization is done by a highly intuitive software.
