  2. Disc brake - Wikipedia

    en.wikipedia.org/wiki/Disc_brake

    Discs are thin, often about 2 mm. Some use a two-piece floating disc style, others use a one-piece solid metal disc. Bicycle disc brakes use either a two-piston caliper that clamps the disc from both sides or a single-piston caliper with one moving pad that contacts the disc first, and then pushes the disc against the non-moving pad.

    The design only allowed for a single front disc brake so a comparatively large 330 mm disc was mated to a six-piston caliper, a world first on a production bike. [9]: 28 The traditional axial caliper mount began to be unreliable when slick tires were introduced, so motorcycles began adopting radially mounted calipers from Formula One car racing.

  5. Hydraulic brake - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_brake

    Brake caliper assembly usually consisting of one or two hollow aluminum or chrome-plated steel pistons (called caliper pistons), a set of thermally conductive brake pads and a rotor (also called a brake disc) or drum attached to an axle. The system is usually filled with a glycol-ether based brake fluid (other fluids may also be used).

    The M4+2 engine, also known as the double-piston internal combustion engine, is a type of internal combustion engine invented by Polish patent holder Piotr Mężyk. [1] The M4+2 engine took its name from a combination of two-stroke engines and four-stroke engines. The two-stroke combustion engine is characterized by a simple construction and ...

  7. Master cylinder - Wikipedia

    en.wikipedia.org/wiki/Master_cylinder

    The most common vehicle uses of master cylinders are in brake and clutch systems.. In brake systems, the operated devices are cylinders inside brake calipers and/or drum brakes; these cylinders may be called wheel cylinders or slave cylinders, and they push the brake pads towards a surface that rotates with the wheel (this surface is typically either a drum or a disc, a.k.a. a rotor) until the ...

  8. Brake pad - Wikipedia

    en.wikipedia.org/wiki/Brake_pad

    When the brakes are hydraulically applied, the caliper clamps or squeezes the two pads together onto the spinning rotor to slow and stop the vehicle. When a brake pad heats up due to contact with the rotor, it transfers small amounts of its friction material onto the disc, leaving a dull grey coating on it. The brake pad and disc (now both ...

    Chassis Brakes International was a multinational manufacturer of automotive brakes and brake components. It was formed in June 2012 when the brakes division of Robert Bosch GmbH was sold to KPS Capital Partners [1] and was based in Netherlands. [2] [3] It was one of the three largest brake system manufacturers in the world. [3]
