Regardless of whether it is a road bike or a mountain bike, the brakes are crucial, and the brakes are the safety guarantee for riding.
The common brake systems of adult bicycles are mainly divided into V brakes, disc brakes, and caliper brakes.
V-brake is a very common brake device on ordinary bicycles. Two brake pads generate friction on the rim of each other to achieve the effect of braking. Because its shape resembles the "V" character, it is called V brake.
2. Disc brakes
The disc brake is composed of a brake disc connected to the wheel and a brake caliper on the edge of the disc. When braking, the high-pressure brake fluid pushes the brake pads to clamp the brake disc to produce a braking effect.
Nowadays, disc brakes have become the mainstream configuration of road bikes and mountain bikes with strong braking force and stable wheel fixation.
Disc brakes can be divided into hydraulic drive and wire-pull drive according to the common driving methods.
Hydraulic disc brakes are brake components that use hydraulic oil as the brake medium. The working principle is that the piston in the brake lever compresses the oil and transfers the pressure through the oil to the caliper to rub the disc to act as a brake. It is also called oil. Disc brakes. Since the oil disc brake uses oil as the medium, the operation process must first ensure the sealing performance, so the oil brake has less force loss during the transmission process, the brake is quite sensitive, the hand feels good, and the operation is smooth.
The cable-pull drive is often called a mechanical disc brake. The brake pads in the calipers rub against and clamp the disc by the pull of the brake cable to produce a braking effect. In terms of price, line brakes are much cheaper than oil brakes. The brake force of the line brake is less than that of the oil brake, but it is completely sufficient for daily riding, especially when riding long distances, many riders will also choose the line brake. Line brakes are more advantageous in terms of weight and maintainability.
3. Clamp brake
Caliper brakes are more commonly used in road bikes and folding bikes. They are also often referred to as C brakes, divided into dual-pivot brakes and single-pivot brakes. Double pivot brakes, the left and right arms are fixed on different pivots and used in conjunction with the brake handle. With the arm positioning fine adjustment knob, the balance of the arms on both sides can be adjusted. Compared with single pivot brake, it has more braking force. The appearance of a single-pivot brake is similar to that of a double-pivot, but there is only one support point, which is located on the fixed axis of the arm.
