2.5.14. Brake system

The design and principle of functioning of brake system are stated in the Head Brake system.

Application of brakes

During movement the right foot should not be constantly on a pedal of a foot brake, — such habit is fraught with an overheat of brake mechanisms, increase in the expense of fuel and considerable reduction of service life brake колодок.

At movement under a bias use braking by the engine, — try not to squeeze out strongly a pedal of a foot brake and move on a hill-climbing gear.

Safety measures

After a crossing through water barriers or journey on a deep pool components of brake mechanisms are humidified that conducts to appreciable decrease in efficiency of braking, — the length of a brake way considerably increases, there can be an effect of loss of course stability during braking (the car will withdraw in one of the parties). Try to move any time with moderate speed, periodically slightly squeezing out a pedal of a foot brake, - soon brake mechanisms will dry out and will return to a mode of normal functioning.

At movement on a slippery road covering try to avoid sharp braking and accelerations, — loss of coupling of wheels with road is fraught with the most serious consequences.

Do not forget that останов the engine during movement it is interfaced to effect of considerable increase of resistance of a pedal of a foot brake to squeezing, — observe vigilance.

System of antiblocking of brakes

The general information

The description of a design and principles of functioning ABS is resulted in the Head Brake system.

Recommendations about security measures at operation of the models equipped ABS

ABS does not reduce a brake way of the car and it is capable to provide only preservation of controllability of the car in the course of braking. In view of told it is necessary to support constantly a safe distance to ahead going vehicle, proceeding from speed of the car and concrete traffic conditions.

ABS does not prevent lateral юз at sharp change of a direction of movement of the car. For example, the car can enter into drift at turn passage on too high speed or at jerk of a wheel during lane change. Always support safe speed of a vehicle, being conformed to a condition of a road covering and traffic conditions.

ABS does not prevent loss of course stability of the car. In the course of emergency braking avoid sharp jerks of a steering wheel.

The brake way equipped ABS the car can exceed a little habitual for models with usual brake system. Told especially considerably at movement on fragile and rough road coverings (gravel, snow). At movement in similar road conditions lower speed and increase a distance to ahead going vehicle.

Operation ABS is interfaced to strong pulsations of a pedal of a foot brake which it is not necessary to be frightened, — during braking hold a pedal constantly squeezed out.

Attempts of squeezing of a pedal of a foot brake by rolling are fraught still with the big increase in a brake way!

Activation ABS occurs only at speeds of movement from 5—10 km/h (depending on road conditions)

Control lamp of infringements of functioning ABS

The self-diagnostics block is included in structure of system of antiblocking. Outwardly procedure of self-diagnostics of system is shown by small pulsations of a foot brake right after engine start. Problem diagnostics ABS is made also at each braking of the car.

At revealing by system of any malfunction on a control panel the corresponding control lamp lights up. Operation of a control lamp testifies that ABS is disconnected. Thus working capacity of working brake system remains to the full, except for function of automatic control of brake effort which is carried out ABS. If control lamp ABS does not die away after start of the engine or joins in movement time, it is necessary to address at the first possibility on the nearest car repair shop.

Joint inclusion of control lamps ABS and refusals of brake system/raising of a lay brake also means switching-off of function of regulation of brake effort that specifies in presence of malfunctions both in ABS, and in brake system. Thus the brake system of the car will continue to provide adequate enough braking of the car, however it is necessary to avoid sharp squeezings of a pedal of a foot brake, — immediately address on the nearest car repair shop.

In operation of control lamp ABS can result also more than 10-second proslipping of wheels at movement on a slippery road covering, — switch off ignition, again start the engine and during some time move with a speed more than 20 km/h. If soon the control lamp does not go out, the car should be driven away on a car repair shop.

At revealing by system of self-diagnostics of infringements of serviceability of functioning ABS in memory of the onboard processor the corresponding digital diagnostic code registers.

Reading of codes is made by means of the special scanner connected to 16-contact diagnostic socket DLC, located at the left under the panel of devices, over pedal assemblage.

In absence near at hand the scanner the car should be driven away for reading of memory and performance of necessary regenerative repair on a car repair shop.

The identification card of codes of malfunctions ABS is led in Specifications to the Head Brake system.

It is necessary to charge performance of any regenerative repair of antiblocking system to experts of car-care centre.
