Check of the brake system

Dust which saves obrazovatelno owing to sale of slips and on components of the brake mechanism may contain asbestos hazardous to health. Do not blow this dust by means of compressed air from you do not inhale them!

Do not use solvents on the basis of gasoline for removal of dust. Dust needs to be removed it is necessary special cleaner of the brake system or metilowym from alcohol in drain power.

After wiping of components of the brake system it is necessary to consider these rags need a damp rag and the maintenance of power of a drain in the closed and signed container. Further you try not to use the components containing asbestos whenever possible.

Except checks the condition of brake mechanisms every time follows certain intervals of time at removal of wheels or at emergence of signs of defect in system to carry out.

For ensuring driving the described low procedures of check of the brake system the most important of all procedures made by you after service of the car.

Signs of defects in the brake system

Brake mechanisms of glasses can have the installed indicators of sale of overlays of friction which signal about it that sale of slips reached critical size. At the same time at once it is necessary to change it is necessary slips, Bremsdisks change also to them demand to be damaged expensive repair.

Each of mentioned below signs can designate on potential defect of the brake system:

   a) When squeezing a foot brake "the car to the party" takes away;
   b) if brake mechanisms at a brake of skrebuschtschije or shrill sounds transfer;
   c) if the foot brake has an increased movement;
   d) if the foot brake pulses (it normally only in operating time of system the Antiblocking device);
   e) If the vytecheniye of brake fluid is observed (usually on inside of the tire or a wheel).

In case of Entdeckens even if at once you watch one of these signs at the brake system.

Brake lines and hoses

In the brake system brake steel listeners, except for the flexible supplied hoses at forward wheels and as associations at a back axis are mainly used. Regular audit of these lines is very important.


 EXECUTION ORDER

1. Park the car out of the blue and exclude the motor. Accept caps of wheels. Weaken, but do not accept bolts of strengthening of all 4 wheels.
2. the car and you, of course, establish to poddomkratte it on support.
3. Take Räd (from it watch Rasdel Poddomkratschiwanije and towage in the introduction to the modern management).
4. Check all brake lines and hoses for existence of cracks and pathetic qualities in its external providing, a vytecheniye, swellings and deformations. Check brake hoses in Forward and back parts of the car for existence of signs of Erweichens, cracks, deformations or sale owing to friction about other components. Check all association schtuzernyje for existence of signs of a vytecheniye and be convinced of reliability of strengthening of all bolts and clips of brake hoses.
5. Bend from hands in and other parties a brake hose to give damages in day. It is not necessary to connect hoses it, - you focus after the color line which is charged on a hose.
6. Turn a steering wheel to the right and on the left before blow. At the same time hoses should not concern for machine design elements.
7. At detection of a vytecheniye of liquid it is necessary to delete at once it is necessary or its damages. For more detailed description of the procedure of repair of the brake system address the head to the brake system.

Check of thickness of Bremsleistens

Thickness of external Bremsleistens can be checked by opening in Disk of a wheel by means of a bulb of bags. Internal levels can check by means of a bulb of bags and a mirror. If it is necessary to estimate Leistens thickness more precisely, it is necessary to accept the wheel is necessary and to measure to levels of a measuring latch.

Brake of glasses of a forward wheel

Shows experiment that it is sale of Bremsleistens of a wheel from the forward passenger more, than from the driver. Therefore the wheel recommended to Bremsleistens to accept for check of thickness from the forward passenger. Observations show that 1 mm of sale of Bremsleistens corresponds to at least 1000 km of the movement of the car. This rule corresponds to adverse conditions of the enterprise of the car. In normal conditions Leistens sale it is significantly less. At a thickness of Leistens of 10.0 mm (with podkladnoj from a disk) still it can be regulated levels of not less than 3000 km.


 EXECUTION ORDER

1. Note from color the provision of a forward wheel concerning the plug. It will allow to establish a balanced wheel into position. Weaken bolts of strengthening of a wheel. At the same time the car has to stand on the earth. Lift a forward part of the car and establish on shelves. Accept a forward wheel.
2. Measure from a measuring latch the integrated thickness of an overlay of friction with the metal basis on an internal and external brake level.
3. The border of sale of Vorderleistens is accepted thickness of 7 mm (considering the basis). In this case brake levels need to replace the brake system, it watch chapter.
4. Establish a forward wheel in such a way that markings coincided which are charged at removal. You do not grease bolts of strengthening of wheels. Establish bolts of strengthening of a wheel.
5. Lower the car on wheels and tighten bolts cross-wise.

Brake of glasses of a back wheel

 EXECUTION ORDER

1. Check thickness of external Bremsleistens opening in Disk of a wheel if it is necessary a bulb of bags it is used. Disk of a wheel accept it should not go. If there is a wheel cap, it is necessary to accept it.
2. You check to internal levels by means of a lamp and a mirror.
3. The border of sale of Bremsleistens of back and forward wheels is accepted thickness of 7 mm, podkladnuju a disk reception.

stojanotschnyj brake

Elementary, and it is possible, the most obvious way of check of work is stojanotschnogo of a brake the car device on a steep slope with the built brake and transmission in neutral situation (when checking it is necessary to be it is necessary for you by car). If stojanotschnyj a brake does not hold the car from skatywanija, is necessary to make this its regulation (watch chapter the brake system).
