2.5.14. Brake system
The design and principle of functioning of brake system are stated in 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 fuel consumption and considerable reduction of service life of brake shoes.
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 low gear.
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 paving try to avoid sharp braking and accelerations — loss of coupling of wheels with the 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 anti-blocking of brakes
The description of a design and principles of functioning of ABS is provided in Head Brake system.
Recommendations about security measures at operation of the models equipped with ABS
ABS does not reduce a brake way of the car and 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 specific conditions of movement.
ABS does not prevent lateral юз at sharp change of the direction of movement of the car. For example, the car can enter into drift when passing turn on too high speed or at wheel breakthrough during lane change. Always support safe speed of a vehicle, being conformed to a condition of a paving and traffic conditions.
ABS does not prevent loss of course stability of the car. In the course of emergency braking avoid sharp breakthroughs of a steering wheel.
The brake way of the equipped ABS car can exceed a little habitual for models with usual brake system. Told especially considerably at movement on fragile and rough pavings (gravel, snow). At movement in similar road conditions lower speed and increase a distance to ahead going vehicle.
Operation of 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 of the constantly squeezed out.
Attempts of squeezing of a pedal of a foot brake by musclemen are fraught still with big increase in a brake way!
Activation of ABS occurs only at speeds of movement from 5 — 10 km/h (depending on road conditions)
Control lamp of violations of functioning of ABS
The self-diagnostics block is switched on in structure of system of anti-blocking. Outwardly procedure of self-diagnostics of system is shown by small pulsations of a foot brake right after engine start. Problem diagnostics of ABS is made also at each braking of the car.
At identification 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 operability of working brake system remains fully, except for function of automatic control of brake effort which is carried out by ABS. If the control lamp of 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 next car repair shop.
Joint inclusion of control lamps of ABS and refusals brake systems/raisings of the parking brake also means shutdown of function of regulation of brake effort that points to existence of malfunctions both in ABS, and in brake system. Thus the brake system of the car will continue to provide rather adequate braking of the car, however it is necessary to avoid sharp squeezings of a pedal of a foot brake — immediately address on the next car repair shop.
To operation of a control lamp of ABS can lead also more than 10-second pro-slipping of wheels at movement on a slippery paving — switch off ignition, again start the engine and for 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 car repair shop.
At identification by system of self-diagnostics of violations of serviceability of functioning of 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 the 16-contact diagnostic DLC socket, located at the left under the dashboard, over pedal assembly.
In absence near at hand the scanner the car should be driven away for reading of memory and performance of necessary regenerative repair on car repair shop.
The ID card of codes of malfunctions of ABS is given in Specifications to Head Brake system.
It is necessary to charge performance of any regenerative repair of anti-blocking system to specialists of car-care center.
