The use and techniques of front and rear brakes when cycling  
　Many beginners prefer to use the rear brake and avoid the front brake because they fear that using the front brake might cause them to flip over. In reality, the front brake is safer in many situations, and learning to use it can be mastered quickly.
　　Basic knowledge about braking:
　　1. The front brake provides better braking performance.
　　2. Brakes achieve their maximum braking power just before locking up; once locked, braking effectiveness drops significantly and balance is more likely to be lost.
       3. Brakes are for controlling speed, not just for stopping.
　　Why do we mainly use the front brake?
　　1. When going downhill, only the front brake has sufficient braking power, because at that time most of the weight of the bike and rider is on the front wheel, increasing the friction between the front wheel and the road. The rear wheel, however, has very little pressure on the road, reducing friction and braking effectiveness, and even a small amount of braking force can cause the rear wheel to lock up and skid.
　　2. The front brake offers better braking performance. Speed control mainly relies on the friction between the wheels and the road, which is proportional to the pressure applied by the wheels on the road. When using the front brake, due to inertia,bicyclethe pressure on the front wheel and the road increases, enhancing braking performance. Using the rear brake does not have this effect, and when using the front brake, the pressure of the rear wheel on the road decreases significantly, resulting in very little friction.
