Each car has its own criteria regarding frequency of replacement of brake pads. Basically, the drivers think that the pads require replacement after 8-10 thousand kilometers. This figure is General and fully focus on it not worth it. Each driver's individual driving style: easy driving, in this case, the pads can work up to 20 thousand kilometers, and the fans of fast driving and sudden stops necessary to change the pads already after 5-6 thousand mileage. In addition, there are many parameters that contribute to wearhave the brake pads: the quality of brake elements, environment, temperature, etc.

Determine the lining thickness brake pads through the inspection hole in the movable caliper bracket. If the thickness of the friction lining is 1.5 mm or less, the pads must be replaced.
6
To check pads the rear brake, put a Jack under the rear wheel and Unscrew them and remove the brake drum.
7
A caliper or a ruler to measure the thickness of the friction lining. If it is less than 1.5 mm, replace the rear brake pads.

If the wheels lock too sharply, it signals the car owner about the fact that lining wearwere eaten at 100% and the metal rubs against metal.

Another sign of the full wearand pads can serve as a brake dust mixed with metal shavings on the disks. When you look under the ROM, rate the appearance of what is there. For example, if the RAID on uniformly dark pads, so the pad still retained. If you see the metallic inclusions, it suggests that the pad is already scratch disk, and to change it it is necessary very urgently.

Strong whistling when braking or the sound of scratching, as if something caught in the wheel and scratching, should alert the motorist.

He says that it's time to change the pads, but the time you still have. And only in the case when the noise becomes continuous, you need to understand what to change pads quickly.
