Realized by a brake pad pressed on the brake braking the brake wheel

Realized by a brake pad pressed on the brake braking the brake wheel. Single axle braking pressure to the brake block and uneven, it is usually more than offset by a pair of brake pads, the pressure on the brake axle suffered brake pad.
Outside hold block brake: it operated device according to the length of the trip is divided into short stroke and long stroke block brake block brake block brake short trip magnet mounted directly on the brake arm. When working around moving core pin rotation to achieve loose brake; tight against the main spring brake when the magnet energized. This brake structure compact, tight and loose brake brake fast action, but the impact force. Long stroke brake block brake lever system can produce large loose brake force, but slow braking action, suitable for large brakes. Within Zhang block brake: Brake blocks located inside the brake wheel through pedal, the brake lever and bumps block open, pressing the inner surface of the brake drum and brake application, the brake pedal is released back to the spring block The brake release. This brake can also be used, such as hydraulic valve or pneumatic operation. Zhang style within a compact block brake structure, dust, and can be used to install space-constrained applications, a wide variety of vehicles.
