How to buy car brake pads?
Four look - first, look at the friction coefficient, the friction coefficient determines the basic brake torque of the car brakes, too high will cause the wheel to lock during the braking process, the direction is out of control and burning, too low braking distance is too long;
Second, depending on the safety, the brake pads of the car will produce instantaneous high temperature during braking, especially in high-speed driving or emergency braking. At high temperature, the friction coefficient of the friction plate will decrease;
Third, whether it is comfortable, including brake feeling, noise, dust, smoke, odor, etc., is a direct manifestation of friction performance;
Four look at the life, usually the brake pads can guarantee a service life of 30,000 kilometers.
Two choices - First of all, should choose the car brake pads produced by the regular manufacturers, with the license number, the specified friction coefficient, the implementation standards, etc., and the package should have the certificate of conformity, production batch number, production date, etc.;
Secondly, choose a professional maintenance point and ask a professional to install.
