An alternative to the current drum brakes, with the increased requirements of todays daily service are disc brakes, in that they offer, in contrast to the drum brakes, the following technical advantages and in turn enhance the active safety of modern commercial vehicles when braking: Enhanced brake pedal-feedback and actuation Improved efficiency Little performance losses when high thermal loads occur (fading). In order to be able to determine the improvement potential of disc brakes they will be compared to the commonly employed Simplex drum brakes. Both wheel brake systems (disc-/drum brakes and all variations) were tested on a computer controlled brake dynamometer and in field tests using a heavy duty commercial vehicle (class 8). The results are compared and conclusions drawn regarding “advantages/disadvantages”.

Although it is the smallest Unimog, Mercedes-Benz claims that the U 20 it is just as capable as the larger models, sharing familiar features such as permanent all-wheel drive, single tires front and rear, differential locks, portal axles to maximize ground clearance, coil springs, power take-offs, and onboard dual-circuit common hydraulics. Standard equipment also includes an air-conditioned cab.
