|1. Disk brake mechanisms can have the built in indicators of deterioration of frictional overlays which signal that deterioration of overlays has reached critical size. Thus overlays should be changed immediately, differently brake disks will be damaged also by it expensive repair is required.|
|2. Any of listed below signs can specify in potential defect of brake system:|
a) At squeezing of a pedal of a brake the car "withdraws" in one party
b) Brake mechanisms at braking publish scraping or squealing sounds
c) the brake Pedal has an excessive course
d) the brake Pedal pulses (it normally only at system ABS work)
e) leaks of a brake liquid (usually on a tyre 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 basically steel brake tubes, except for the flexible reinforced hoses at forward wheels and as connections at the back bridge are 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. Loosen the, but do not remove bolts of fastening of all four wheels.|
|5. Поддомкратьте the car and reliably establish it on support.|
|6. Remove wheels.|
|7. Check up all brake lines and hoses on presence of cracks and attritions in their external covering, leaks, swellings and deformations. Check up brake hoses in forward and back parts of the car on presence of signs of a softening, cracks, deformations or deterioration as a result of a friction about other components. Check up all штуцерные connections on presence 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 a direction of the colour 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 leaks of a liquid or their damages it is necessary to eliminate immediately. |
|Check of a thickness brake колодок|
The thickness external brake колодок can be checked up through an aperture in a disk of a wheel by means of a pocket small lamp. Internal колодку it is possible to check up by means of a pocket small lamp and a mirror. If it is necessary to estimate more precisely a thickness Pads, it is necessary to remove a wheel and to measure колодку by a calliper.
|Disk brake of a forward wheel|
Experience shows that deterioration brake Pads wheels from outside the forward passenger more than from outside the driver. Therefore for check of a thickness brake Pads it is recommended to remove a wheel from outside the forward passenger.
|11. Mark a paint position of a forward wheel in relation to a nave. It will allow to establish отбалансированное a wheel in the working position. Loosen the 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 a thickness Pads and with a metal lining on internal and external brake колодках.|
|13. A limit of deterioration of a lobby Pads the thickness is considered of 7 mm (with a bearing plate). In this case brake колодку it is necessary to replace, address to subsection Replacement of lobbies brake колодок.|
|14. Establish a forward wheel so that the marks put at removal have 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 120 H·м.|
By experience, 1 mm of deterioration brake Pads corresponds at least 1000 km of run of the car. This rule corresponds to adverse service conditions of the car. In normal conditions deterioration колодок is much less. At a thickness Pads 10.0 mm колодка can be maintained still not less than 3000 km.
|Disk brake of a back wheel|
|15. Check up a thickness external brake Pads through an aperture in a wheel disk, having taken advantage if necessary of a pocket small lamp. It is not necessary to remove a wheel disk. If there is a wheel cap, it is necessary for removing.|
|16. Internal колодку check up by means of a lamp and a mirror.|
|17. A limit of deterioration brake Pads back and forward wheels the thickness is considered of 7 mm, including a basis plate.|
|18. The elementary, and it is possible, the most obvious way of check of work of a lay brake is car installation on an abrupt slope with the cocked brake and transmission in neutral position (at check you should be in the car). If the lay brake does not keep the car from скатывания, it is necessary to make its adjustment.|
