The difference between bicycle V brakes and disc brakes

The application of brakes on bicycles is mainly based on V brakes and disc brakes.

V brake: V brake is braked by holding the rim tightly by the V brake caliper
Disc brake: The disc brake is braked by a caliper (or called a caliper) on the steel disc fixed on the hub.
Both disc brakes and ‘V’ brakes use force on objects to generate friction to reduce vehicle speed. The biggest difference between the two is that the'V' brake uses brake pads to brake the bicycle rim, while the disc brake is specially equipped with disc brake pads. The brake pads in the brake caliper generate frictional pressure on the brake pads. brake.
Types of disc brakes

Disc brakes for sports bicycles are mainly divided into two types, one is cable-pull disc brake (mechanical), and the other is hydraulic disc brake
1. Cable-pull disc brakes, relying on the tension of the brake cable to make the brake pads (coming pads) in the calipers rub against and clamp the disc to produce a braking effect;
2. Hydraulic disc brakes use oil as the medium. The piston in the brake lever is actuated to compress the oil. The pressure flows from the oil pipe to the caliper, thereby pushing the piston in the caliper to drive the brake pads to clamp the disc.
The main difference between the two disc brakes is the transmission medium. Cable-pull disc brakes brake the discs by pulling on the brake cable; hydraulic disc brakes apply pressure to the brake fluid in the oil pipe and use the oil to push the brake pads to brake the discs. Therefore, the cable-pull disc brake is similar to the principle of the most common ‘V’ brake we usually use. Except for the discs and brake pads, the rest of the two are basically the same. Hydraulic brakes are different. The brake levers, hoses and calipers of hydraulic disc brakes are a complete set of products.
