Every driver sooner or later finds himself/herself in a situation where an emergency braking is necessary. Emergency braking or even braking on a wet or slippery surface can cause the wheels of the vehicle to lock. Locking wheels reduce the adhesion between tires and the road surface and make the vehicle unsteerable. The antilock braking system (ABS) from Bosch prevents the wheels from locking and enables safe braking.

a second ABS reduces brake pressure then increases it again, if a wheels locks up. This keeps braking distances short, even on slippery surfaces, and the vehicle remains steerable.



the success story of ABS began with the start of production of the first electronically controlled four-wheel antilock braking system for passenger cars. It was a development Bosch engineers had been working on for nine years.
