1. Qualified friction coefficient
The friction coefficient is the most basic parameter of the friction material, and determines the basic brake shoe braking torque. The national standard on the strict requirements of the manufacturer must be marked on the packaging friction coefficient. The friction coefficient must be appropriate, too high will cause the brake during the wheel lock, the direction of out of control and burning, too low the braking distance is too long.
2. Reliable security
Brake pads produce instantaneous high temperatures during braking, especially at high speeds or in emergency braking. In the high temperature state, the friction coefficient of the friction plate will decline, known as the thermal decline. The level of thermal decay determines the safety of high temperature conditions and emergency braking.
3. Satisfied comfort
Comfort is a direct manifestation of friction performance, including the brake feel, noise, dust, smoke, smell and so on. With the increase in private cars and the improvement of people's living standards, in the basic premise to meet the safety, comfort has become an important indicator of friction plate.
4. Reasonable life expectancy
Life is the product of general concern. Usually the brake pads can guarantee a service life of 30,000 km. The large particles of graphite and brass used in Bosch brake pads can also reduce the wear on the brake discs.
It is recommended that owners choose to replace the brake pads, try to choose the original pieces. Of course, the original pieces in the quality is certainly guaranteed, but the relative price should be more expensive. But the saying goes, a penny of goods, these things we should spend the flowers, safety first.
And, if the owners are in the repair shop to replace the brake pads, you need to be very cautious. Because some maintenance shop selected brake pads in order to save costs, steel back does not set the alarm line, even if the friction material all wear finished, there will be no whistle. This is quite dangerous.
