ATVs use hydraulic disc brakes, with some featuring drum brakes. Metal discs are mounted to the wheel and work with brake pads. Brake lines can be made of metal, plastic, or composite materials. Brake pad materials vary and depend on usage and desired stopping power.
Like other types of vehicles, an ATV requires a braking system to slow or stop the machine during use. Hydraulic disc systems are the most common types of ATV brakes, and almost all ATVs on the market will have disc brakes. Some ATVs may also feature drum ATV brakes, but these are less common than disc brake setups. The specific components within each system can vary in materials and design, though the general function generally remains the same: a master cylinder is used to apply pressure to oil within a hydraulic line, which in turn activates pistons in a caliper. brake.
The metal discs must be mounted to the ATV wheel, usually around the hub. This metal disc is designed to work in conjunction with the brake pads, which will compress on either side of the disc when activated. The disc typically features a series of holes that help keep the system cool during the high-friction braking process. If other styles of ATV brakes, such as drum brakes, are used instead of disc brakes, this disc will not be present in the hub. Instead, a thick metal drum will be mounted to the hub, and a wheel cylinder will activate the brake pads, pressing them outward against the inside of the drum.
Some ATV brakes feature a metal hydraulic hose in which the brake fluid will be present. Metal lines are efficient at resisting damage from impacts, and the lines will not expand when pressure is exerted on the internal fluid. Other ATV systems may use lines made of plastic, braided steel, or other composite materials that are designed to resist swelling when the fluid inside is activated. The lines must resist swelling to increase the amount of pressure transferred directly to the brake pistons inside the caliper.
Variation in ATV brakes will often come in the form of various brake pad materials. Ceramic brake pads, asbestos brake pads, and semi-metallic brake pads are all fairly common options. Choosing the right one generally depends on what type of conditions the ATV will be used in, what type of braking system is already present on the vehicle, and how much stopping power the rider wants relative to the amount of pad wear that will occur over time. . The price of the pads can also vary; Ceramic pads tend to be quite expensive, while asbestos pads tend to be cheaper.
