1. The state of brake system components, in addition to regular, agreed the schedule of routine maintenance checks must be assessed each time the wheels are removed or if there is a violation of the operation of the braking system. Pads disk brake mechanisms are usually equipped with special indicators are notified of excessive wear of the friction linings characteristic squeal during braking.
2. The following symptoms may indicate a malfunction of components of brake mechanisms:
a) If braking car loses directional stability (withdrawal takes place in one of the parties);
b) In the braking brakes squealing or creaking issue;
c) Excessive increases foot brake pedal;
d) If squeezing the brake pedal pulsations are felt;
e) have the following leakage of brake fluid (usually on the inner surface of the drive wheels and tires).
3. Loosen the wheel nuts.
4. Poddomkratte car and establish it on props.
5. Remove the wheel.
6. The support of each of the brake is equipped with two blocks - internal and external.
7. The ends of the pad can be easily seen through a special viewing window in the housing support, as well as the ends of the latter after removing the wheel. Evaluation of the remaining thickness of the friction lining the inner pad is made visually through the above-mentioned observation window. If the pads are worn more than the permissible limit (see. Specifications), you must produce a comprehensive replacement of brake pads.  | Remember that the friction linings are riveted or bonded to a metal substrate, the thickness of which must not be taken into account when measuring. |
8. If a visual estimate of the residual thickness of the pad is difficult, or there is a need for a more detailed inspection of pad, remove the caliper (s) and remove the pads for a more detailed study (see chap. Brake System).  | 9. Once the pads are removed from the support, clean them using the special tools and measure the residual lining thickness using a ruler and calipers with vernier scale. |
10. micrometer, measure the thickness of the brake discs. Compare your results with the regulatory requirements (see. Specifications). If the thickness of any of the disks is out of the acceptable range, replace it (see chap. Brake System). If the thickness of the disk is normal, check its general condition. Pay attention to the defects such as deep scratches, grooves, burrs, traces of overheating, etc., if necessary, remove the disk and put him into the groove (see chap. Brake System).
 | 11. Before installing the wheel in place, inspect all brake lines for signs of damage, wear and tear, damage due to aging of the material, traces of leaks, bending, twisting and other deformations (especially near the connection points of flexible brake hose to brake caliper) . Check for loose hose clamps. Make sure that none of the brake hose does not come into contact with sharp edges of the neighboring body components, exhaust system and suspension (at any position of the steering wheel). If necessary, make the appropriate repairs or Adjust the route of the line. Defective components replace (see chap. Brake System). |
