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.
About weare pad indicates the presence of brake dust mixed with metal shavings on the wheel disks, and also very sharp, or, on the contrary, excessively weak inhibition, the presence of beats at the time of braking. If your car has similar problems, check the brake pads.
To check the degree of wearand the brake pads and front brake, set the car on a viewing hole or the Jack.
Telescopic wrench remove the front wheels. When checking the brake pads of the brake mechanism on the left, turn the steering wheel left and right while checking the brake system elements – the steering wheel to the right.
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.
To check pads the rear brake, put a Jack under the rear wheel and Unscrew them and remove the brake drum.
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.
Advice 2: How to determine the pad wear
Brake pads - it is the second shift after the oil is consumable in the car. If you skip a time when you need to replace them, it can turn cars into a lot of trouble. Besides smart appliances advance warning when you need to change them.
If you feel when braking a slight runout - it just means that the service life of brake pads your vehicle came to an end. This happens because they are erased unevenly, and because of this there are various chips and cracks. Order wearusasa brake system starts making a noise and runout. Importantly, this process does not start, or may suffer brake discs. And then the repair will cost you a large amount. And spent on the repair time will increase significantly.
If the braking system starts to behave inadequately, it is also a symptom of problems in the stocks. Their wear indicates such factors as too weak or, conversely, excessively hard braking. 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. The thing is that the brake pads have a special limiter, which as erasing brakes approaches the disk and begins to scrape on it. Hence, there is a characteristic sound. 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.
You need to change pads in the following cases: the thickness of the lining is less than 1.5 mm, the lining is poorly connected to the base, the surface of the pads greasy.
