First you have to make sure your wheels are installed in place. For non-bucket axle wheels, first, confirm whether your wheels have been installed in place. Open the quick release, press the frame with your body, and then lock the quick release in place. Incorrect installation will cause the disc to tilt against the disc. For the barrel axle wheelset, before adjusting the position of the brake caliper, the barrel axle rod must be locked to a predetermined torque and then adjusted to prevent the disc position from changing after disassembling the wheelset.
Do you know the basic knowledge of bicycle brakes?
1. The brake is used to control speed, not just for parking.
2. The front brake has a better braking effect.
3. The brake has the maximum braking effect when it is locked, and the braking performance is greatly reduced after locking and it is easy to lose balance.
Many novices prefer to use the rear brake and use the front brake less because they are worried that using the front brake will cause somersaults. In fact, the front brake is safer in many situations, and learning to use the front brake can also be learned quickly.
Many novice friends don't like or are afraid to use the front brake. In fact, the front brake is still very useful. Especially in the case of emergency braking, the front brake is more efficient than the rear brake. But you need to pay attention to two issues. The focus should be shifted back if you don't want to fly out.
Also, the brakes are now very easy to lock, so be sure to pay attention when using the front brake. This can be felt slowly while riding.
If it is downhill, you can't just use the front brake, you need front and rear cooperation.
It is not recommended to use the front brake when cornering. It is easy to slip. When using the front brake, the wheels must be straight.
Generally speaking, 140mm and 160mm discs are mostly used in road bike brakes. 160mm discs have stronger braking force, can better cope with certain situations, and can also ensure the best braking effect. In addition, a larger disc heat dissipation area is also larger, which can further improve the overall performance of the brake. The 140mm disc is the most aesthetic standard, but if many riders weigh more than 80kg, the braking force of 140mm discs is not enough for them, so you can use the front 160mm rear 140mm configuration, the overall center of the brake is The front brake is more dependent on the braking force of the front brake. If the rear wheel is relatively strong and the rear wheel locks and slips, it is not a good thing. Therefore, it is also a feasible solution to configure the rear wheel with 140 discs with weaker braking force. Weight reduction of the whole bike.
