|1. Disk brake mechanisms can have the built-in indicators of wear of frictional slips which signal that wear of slips reached critical size. Thus slips should be changed immediately, differently brake disks will be damaged and they will need expensive repair.|
|2. Any of listed below signs can point to potential defect of brake system:|
a) When squeezing a pedal of a brake the car "withdraws" in one party
b) Brake mechanisms when braking publish scraping or squealing sounds
c) The pedal of a brake has an excessive course
d) The pedal of a brake pulses (it normally only at ABS system work)
e) Leakages of brake liquid (usually on tire or wheel inside) are observed.
|3. In case of detection at least one of these signs immediately examine brake system.|
|Brake lines and hoses|
In brake system steel brake tubes, except for the flexible reinforced hoses at forward wheels and as connections at the back bridge are generally used. Regular survey of all these lines is very important.
|4. Park the car on an equal platform and switch off the engine. Remove caps from wheels. Weaken, but do not remove bolts of fastening of all four wheels.|
|5. To Poddomkratta the car and reliably establish it on support.|
|6. Remove wheels.|
|7. Check all brake lines and hoses on existence of cracks and attritions in their external covering, leaks, swellings and deformations. Check brake hoses in forward and back parts of the car on existence of signs of a softening, cracks, deformations or wear as a result of a friction about other components. Check all shtutserny connections on existence of signs of leaks and make sure of reliability of fastening of all bolts and clips of brake hoses.|
|8. Bend hands in one and other parties a brake hose to reveal damages. To braid hoses does not follow. Watch the direction of the color line put on a hose!|
|9. Turn a steering wheel to the right and to the left against the stop. Hoses should not touch elements of a design of the car thus.|
|10. At detection of leakages of liquid or their damages it is necessary to eliminate immediately. |
|Check of thickness of brake shoes|
The thickness of external brake shoes can be checked through an aperture in a wheel disk by means of a pocket small lamp. The internal block can be checked by means of a pocket small lamp and a mirror. If it is necessary to estimate more precisely thickness of a block, it is necessary to remove a wheel and to measure a block by a calliper.
|Disk brake of a forward wheel|
Experience shows that wear of a brake shoe of a wheel from the forward passenger more than from the driver. Therefore for check of thickness of a brake shoe it is recommended to remove a wheel from the forward passenger.
|11. Mark paint the provision of a forward wheel in relation to a nave. It will allow to establish an otbalansirovanny wheel in the working situation. Weaken bolts of fastening of a wheel. Thus the car should stand on the earth. Lift a forward part of the car and establish on supports. Remove a forward wheel.|
|12. Measure by a calliper thickness of a block and with a metal lining on internal and external brake shoes.|
|13. A limit of wear of a forward block the thickness of 7 mm (with a bearing plate) is considered. In this case it is necessary to replace a brake shoe, address to subsection
Replacement of forward brake shoes.|
|14. Establish a forward wheel so that the markings put at removal coincided. Bolts of fastening of wheels are not greased. Establish bolts of fastening of a wheel. Lower the car on wheels and tighten bolts cross-wise the moment of 120 H · m.|
By experience, 1 mm of wear of a brake shoe corresponds at least 1000 km of run of the car. This rule corresponds to adverse service conditions of the car. In normal conditions wear of blocks is much less. At thickness of a block of 10.0 mm the block can be maintained still not less than 3000 km.
|Disk brake of a back wheel|
|15. Check thickness of an external brake shoe through an aperture in a wheel disk, having used if necessary a pocket small lamp. It is not necessary to remove a disk of a wheel. If there is a wheel cap, it is necessary for removing.|
|16. An internal block check by means of a lamp and a mirror.|
|17. A limit of wear of a brake shoe of back and forward wheels the thickness of 7 mm, including a basis plate is considered.|
|18. To protozoa, and it is possible, the most obvious way of check of operation of the parking brake is car installation on an abrupt slope with the cocked brake and transmission in neutral situation (at check you should be in the car). If the parking brake does not hold the car from a skatyvaniye, it is necessary to make its adjustment.|
