2.5.4. Brake system
The brake system of the considered cars is equipped by the vacuum amplifier allowing for braking with a certain intensity to put smaller effort to a brake pedal, than it would be required without amplifier. If the amplifier does not work (at the idle engine or for other reason), working brake system remains serviceable, however it will be required to press on a brake pedal with considerably bigger force, and the brake way 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 deduction of the car on the slippery road).
In case of refusal brakes during the movement braking by means of the parking brake is allowed, however it is necessary to remember that the brake way in this case will exceed much more a brake way when using working brakes always.
Use of the parking brake at the movement of the car with a normal speed can cause driving loss therefore if it is necessary to use the parking brake for a stop of the moving car, act especially accurately.
It is not necessary to hold a leg on a brake pedal at the movement of the car since it leads to heating and premature wear of brake mechanisms and increase in a brake way. At the movement on a slope do not use brakes too long, instead use braking by the engine, switching to the lowering transfers. After the movement during a rain, and also after overcoming a water barrier it is necessary to dry brake mechanisms, having slightly pressed a pedal of a brake and holding it until productivity of brakes does not return on normal level.
Arrangement of a pedal of the drive and handle of an otpuskaniye of the parking brake. For raising of the parking brake press a pedal; for an otpuskaniye of the parking brake pull on yourself the handle.
Do not use the transmission established on transfer instead of the parking brake. On the parking surely you cock the parking brake and install the AT selector lever in situation "P".
At a stop on rise park the car as it is possible closer to the sidewalk or a roadside and turn wheels to the center of the road that at the casual movement of the car back forward wheels would rest against curbstone.
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 the casual movement of the car back forward wheels would rest against curbstone.
At each start of the engine check To/L the brake system (see the Part the car Equipment, an arrangement of devices and governing bodies) – at the cocked KL parking brake has to burn, and after its otpuskaniye To/L has to die away.
System of anti-blocking of brakes (ABS)
The ABS system at achievement of speed of the car more than 10 km/h constantly traces the speed of rotation of wheels of the car and at their blocking repeatedly modulates hydraulic pressure in the brake system. Regulation of pressure is carried out separately for each forward wheel and for both back wheels. Thanks to such scheme braking of both back wheels is identical and stability of the car does not worsen.
When braking in conditions which can lead to blocking of wheels and also at self-diagnostics of system, it is possible to hear clicks in brake mechanisms, or to feel brake pedal pulsations. The listed phenomena are a consequence of normal work of the ABS system and mean its activity. It is not necessary to change at the same time effort of pressure upon a brake pedal since it will prevent the ABS system to work with maximum efficiency.
It is necessary to remember the following precautionary measures always:
- Even in the presence of the ABS system the car cannot be stopped instantly, – you hold a safe distance;
- Always reduce speed on turns since the ABS system cannot prevent emergence of accident at a high speed;
- When braking on the uneven road with ABS use the brake way can be longer, than without ABS use;
- Do not neglect the general safety rules of traffic.
Check To/L the ABS system at start of the engine, – it has to light up for several seconds, and then go out. If To/L does not die away, ABS means it is faulty, at the same time the working brake system can normally function.
When falling speed of the car lower than 6 km/h of ABS are disconnected.
