This paper describes the influence of shock absorbers' technical condition on the vehicle braking process on two types of surface with the Anti-Lock Braking System activated and deactivated. During each of the road tests the vehicle stopping distance, the braking deceleration, and the force applied on the brake pedal were determined. The test plan includes various road surfaces and technical conditions of shock absorbers. The established characteristics of the stopping distance and the deceleration allow the determination of the relations between the technical condition of the shock absorbers, the road surface, and the efficiency of the braking system. In addition, this paper presents the construction and the principle of operation of the Anti-Lock Braking System, which is one of the basic active safety systems.
