The brake system of considered cars is equipped by the vacuum amplifier allowing for braking with certain intensity to put to a pedal of a brake smaller effort, than it would be required without the amplifier. If the amplifier does not work (at the idle engine or for other reason), the working brake system remains serviceable, however to press on a pedal of a brake is required with bigger force, and the brake way, as a rule, will increase.
At the idle engine by each pressing a brake pedal the additional effort of braking decreases, therefore it is not necessary to press a brake pedal at the idle vacuum amplifier without need (for example, at driving deduction on the slippery road).
In default brakes during movement braking by means of the parking brake is allowed, however it is necessary to remember always that the brake way in this case will exceed much more a brake way when using working brakes.
Lobbies and back brake mechanisms
On considered cars disk brake mechanisms are established. Indicators of their wear which start to publish a high-pitched sound at movement or by pressing a brake pedal if slips demand replacement are built in brake slips. Thus it is necessary to replace slips whenever possible rather to avoid further more expensive repair.
On the European models the lever of the parking brake is located on the central console, between forward seats. For raising of the parking brake pull the lever up against the stop. For an otpuskaniye of the parking brake press the button located on the free end of the lever, and lower the lever down, holding the button of the pressed.
On the American models the parking brake is given by a pedal (see an illustration the Scheme of an arrangement of elements of management on the dashboard). For raising of the parking brake press a pedal of working brake system and, holding it, squeeze out a pedal of a drive of the parking brake and release a pedal of a working brake. For an otpuskaniye of the parking brake press a pedal of a working brake, then, holding it, press and release a pedal of a drive of the parking brake – it should return to the top situation.
At a stop on lifting park the car as it is possible closer to the sidewalk or a roadside and turn wheels to the road center that at casual movement of the car back forward wheels would rest against a bordyurny stone.
At a stop on descent park the car as it is possible closer to the sidewalk or a roadside and turn wheels to a roadside that at casual movement of the car back forward wheels would rest against a bordyurny stone.
At each start of the engine check To/l brake system (see. The car equipment, an arrangement of devices and governing bodies) – at the cocked K L parking brake should burn, and after its otpuskaniye To/l should die away. If after an otpuskaniye of the parking brake it To/l continues to burn, it indicates malfunction in brake system which should be corrected before to begin movement. If To/l lit up during movement, stop at the first possibility and eliminate malfunction.
System of anti-blocking of brakes (ABS)
The ABS system constantly traces speed of rotation of wheels of the car and at their blocking repeatedly modulates hydraulic pressure in brake system.
When braking in conditions which can lead to blocking of wheels, it is possible to hear clicks in brake mechanisms, or to feel pulsations of a pedal of a brake. The listed phenomena are a consequence of normal work of ABS system and mean its activity. It is not necessary to change thus effort of pressure to a brake pedal since it will prevent ABS system to work with maximum efficiency.
It is necessary to remember the following precautionary measures always:
Check To/l ABS system at engine start, - it should light up for 2-3 seconds, and then go out. If To/l does not die away, ABS means is faulty, thus the working brake system can normally function. To/l ABS system can join and at long braking on the slippery road. If it occurred, stop and muffle the engine. If after restart of To the/l engine will not go out, drive away the car on HUNDRED for diagnostics and malfunction elimination.
