Brake system of the car Opel Vectra B
The car uses a working brake system with hydraulic drive and diagonal separation of circuits, which significantly increases the safety of driving a car. The brake system consists of a master cylinder, a vacuum brake booster, disc brakes on the front wheels, and drum or disc brakes on the rear wheels. All models are equipped with an anti-lock brake system, consisting of a hydraulic modulator, an electronic control unit, a relay and wheel speed sensors. The system prevents the wheels from locking during heavy braking. On vehicles with diesel engines, a separate vacuum pump is used to create a vacuum that ensures the operation of the vacuum brake booster, which is installed at the end of the cylinder head and is driven directly from the camshaft (models 1.7 l) or attached to the generator (models 2, 0 l)
