Coefficient of friction
The most important performance brake indicator is the coefficient of friction. National standards for brake friction coefficient between 0.35-0.40. Qualified brake friction coefficient is moderate, stable, if the friction coefficient is lower than 0.35, the brakes will exceed safe braking distance even brake failure, if the friction coefficient is higher than 0.40, prone to sudden brake locking, rollover accidents occur.
National non-metallic mineral products quality supervision and inspection center staff: \"national standards, should be greater than 350 degrees, the friction coefficient 0.20,
Maintenance method
coup1: if feel brake less sensitive, when red light to trample brake a few feet can.
The coup: to replace air filter with the same size of the sponge, is added into the air, reoccupy after washing, and winter defrosting fast inside the car.
Coup 3: sticking to front wheel inside protective plate on a layer of black felt cloth or flannelette, can reduce the tire noise.
Coup 4: the wiper joint and rubber pieces with forceps gap down, can eliminate the wiper plate vibration and noise.
Coup 5: the new bulbs with alcohol to wipe again, remove the fingerprints and oil, can prolong the service life of the bulb.
Coup 6: will play a small hole muffler below the lowest place, can prolong the service life of the muffler.
Pay attention to the choose and buy
Buy brake pad choose pay attention to four
Four 
1  look at the coefficient of friction, the friction coefficient of basic brakes brake torque, too high will cause in the process of braking wheel lock, direction and burning out of control, and low braking distance is too long;
2  depends on security, brake pads in the brake will produce instantaneous high temperature, especially in the high speed or emergency braking, the high temperature condition, friction lining friction coefficient will decline;
3  see whether comfortable, including brake feeling, noise, dust, smoke, odor, etc., is the direct embodiment of friction performance;
4  see life, usually brake pads can ensure the service life of 30000 km.
Two choice
first of all, should choose to normal manufacturer of production, has a license, specify the coefficient of friction, standards, such as car brake pads, and inside the box should have certificate of approval, the production batch number, production date, etc.;
Second, choose to professional maintenance point please professional installation.
