General checks of the system of brakes
|
|
The powder that is formed as a consequence of the mistakes use and it being accumulated in component of the brake mechanism can contain the asbestos risked for the health. Do not take this powder through the compressed air and do not inhale it! Do not use solvents on basis of the gasoline of the removal of the powder. |
|
|
Except bill separately the intervals of time established a condition of mechanisms of brake that is necessary to execute every time in the moment of the removal of wheels or in the moment of the emergence of signs of the bad functioning in the system. |
Signs of bad functioning in the brakes system
The mechanisms of brake of disc have the built indicators of the use of mistakes of friction that they transmit that the mistakes use got the critical size. At the same time the mistakes must modify immediately, otherwise to curb the discs are going to be damaged and they will need the expensive repair.
Some of the enumerated ones below of signs can indicate the potential defect of the system of brakes:
- Holding tight a pedal of a brake the car "gets a beating" in a party;
- The brake mechanisms braking do the splinter or sharp scream of sounds;
- The pedal of a brake has the excessive course;
- The pedal of a few wrists of brake (link normally only during the work of the system ABS);
- The hole of fluid of brake is observed (tires normally obvious in the interior or wheels).
In case of the detection at least of one of these signs immediately they examine the system of brakes.
Lines of brake and hoses
|
|
In the tubes of brake from steel of system of brakes, except the flexible reinforced hoses in wheels they are in use generally. The regular inquiry of all these lines is very important. |
Check of thickness of shoes of brake and discs
|
|
- The car also establishes the Poddomkratta in stakes then it withdraws the corresponding wheel.
|
|
- Check the thickness of bedcovers of shoes of brake and through an opening in a support of the mechanism of brake.
|
- The thickness of a 1,0 mm bedcover is considered a limit of the use of a block (without metal substrate). In this case the brake shoe must be substituted (the Head sees the System of brakes).
|
|
As a rule, 1 mm of the use of a shoe of brake corresponds, at least, to 1.000 km of a race below averse service conditions. In usual conditions of a mistake they are put out much more slowly. In this way, in a thickness of the bedcover of 3,0 mm brake (without a substrate) the brake shoes will be enough Meantime, at least, for 1.500 km of a race. |
- In case of the doubt in the fairness of the measurement they withdraw shoes of brake and measure the thickness of mistake for a calibre beat. If the degree of the use is already got, substitute shoes of brake. At the same time substitute 4 bedcovers of wheels of an axle, even in case of what only a mistake was worn away.
- Check supports of the mechanism of brake of the existence of holes. In holes urgentemente they repair a support of the mechanism of brake.
- Visually check discs of brake of the internal and exterior side of the existence of furrows, rust, slits, if necessary it substitutes discs.
|
|
- Thickness of measure of discs of brake at several places through a micrometer or a beat of special calibre. Also it is possible to measure the thickness of a disc of brake for a beat of usual calibre, having enclosed of each his party a revetment of the known size (for example, two coins), and soon having subtracted revetment of thickness of the measured value.
|
- The brakes System compares the minimum of the results received the demands of Specifications to the Head. If the limit of the use is got, substitute certainly both discs of brake of wheels in an axle. The brake disc must be substituted also in great slits or furrows with the depth of more than 0,5 mm.
- Establish wheels and lower the car in the land.

|
Check of the brake of parking
|
|
- Park the car in a clear surface and launch the brake of parking.
- The car has to move manually, the action of brakes must not be felt.
- Lift the lever of the brake of parking in 1 click (the European models) or hold tight a pedal of the brake of parking (the American models), the car will remain at the place in the attempt of moving it manually.
- Completely lift the lever of the brake of parking (the European models) – it must not be lifted any more, of what in 5 clicks. Otherwise adjust the brake of parking (the Head sees the System of brakes).
