A disc brake is a type of brake that uses calipers to squeeze pairs of pads against a rotor (or “disc”) in order to create friction that retards the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary.
Types of disc brake pads
Sintered: Sintered pads are the hardest wearing compound and most popular type of disc brake pad.
Organic: These pads are made of organic materials, providing the most powerful option. Although more-powerful
Semi-organic: These are not always an option with after-market brake pads, but offer a good combination of power and longevity.
Disc Brake Caliper Maintenance
Wiggle the caliper to make sure it moves freely, then pull the corresponding brake lever, hard. This will clamp the caliper to the rotor. Hold the brake lever down to keep the caliper in place, meanwhile tightening the top bolt until snug. Tighten the bottom bolt until snug and then re-tighten the top bolt to torque spec, then the bottom one.
Most of electric bikes produced by Shuangye have the 160 disc brake,modern day mountain bike frames built for off road performance will be constructed with disc brake mounts instead of cantilever mounts.
