First look to buy four methods, see the friction coefficient, friction coefficient determines the basic brakes braking torque is too high will cause the wheels from locking during braking, direction out of control and burned pieces, the braking distance is too low for too long; Second, look at the safety of aramid fiber prices brakes, brake pads during braking will produce instantaneous high temperature, especially at high speeds or emergency braking, the high temperature state price Linyi brakes, friction coefficient of friction drops; three to see is comfortable, including brake feel, noise, dust, smoke, odor, etc., is directly reflected in the performance of friction; four to see life, usually brakes to ensure the life of 30,000 km. So when it would need to replace the brake pads do? Usually when the following situations, we believe it is necessary to replace the brake pads up: 1. When the brakes are large oil pollution; 2. brakes abnormal wear or fracture. Which brakes abnormal wear or broken brake pads is easy to understand, but in regard to oil pollution problem is due to a mixture of brake pads themselves from a variety of materials in the manufacture of high-pressure process, the number of different molecular materials will there is a gap a little, once infiltration grease a large area, it is easy to lead to the molecular structure of block brake pads are changed, resulting skid brakes, strength is lowered even brittle.
