If you have ever driven a car or truck with a fully locked differential around a tight corner or tried to get a car with an open differential out of a snowbank, you know about the benefits of a limited-slip differential. These can be found on performance cars and off-road trucks. The two wheels are connected using spider gears.

Unlike 4×4 truck systems of the day, these systems were always engaged and could not be disengaged by the driver. The brake hydraulic control module on these vehicles has at least 12 valves. If the car or truck is accelerating hard from a stop, the ETS will apply the brakes independently to prevent slipping.

It could be a Chevy pickup truck with active dampeners and air ride or a Mercedes S-Class with ABC hydraulic dampeners. These systems include hydraulic, magnetic and air-ride systems. The torsion bar is controlled by hydraulic pressure using a hydraulic servomechanism.

Over the next few decades, many ideas and applications were used by both militaries and truck/automotive manufacturers. Seals, air lines and electronic components are also subject to wear and tear. Today there are traditional air systems as well as air-over-magnetic and air-over-hydraulic. These systems vary greatly.

At the master cylinder on some vehicles, there might be a quick-take-up valve in the replenish port to hydraulically pull the caliper piston back from the rotor. Some vehicles are even using the valves in the ABS module to electronically retract the pistons. This abutment clip has a metal finger that pushes the pad away from the rotor.

With a proper set of snow tires it was all but unstoppable, and I took a great bit of satisfaction from pulling 4WD trucks out of the ditch after a heavy snowfall. Figure 4 ESP and ETS All 4MATIC systems use an Electronic Traction System (ETS) and an Electronic Stability Program (ESP).
