The brake disc or rotor is the main rotating component of the disc brake unit. The wheel is bolted to the rotor and they rotate together, leading some manufacturers to integrate the anti-lock brake system (ABS) tone wheel into the rotor. Since friction between the rotor and brake pads generates great amounts of heat, rotors … Read more

Friction is the force that acts to prevent two surfaces in contact from sliding against each other. The amount of friction between two surfaces is expressed as a ratio and is called the coefficient of friction. When friction occurs, the kinetic energy (motion) of the sliding surfaces is converted into thermal energy (heat). Some combinations … Read more

Fixed and sliding/floating calipers. In most applications, the disc brake caliper assembly is bolted to the vehicle axle housing, or steering knuckle, and clamps the brake pads onto the rotors to slow the vehicle. Take a peek at casino bonus ohne einzahlung. There are two main types of calipers: fixed calipers and sliding or floating … Read more

In disc brake calipers, the piston is sealed by a stationary square section sealing ring, also called a square cut O-ring FIGURE 32-11. This O-ring has a square cross-section and is fitted in a machined groove in the caliper. The O-ring is compressed between the piston and caliper housing, creating a positive seal to keep … Read more

Floating calipers are mounted in place by guide pins and bushings FIGURE 32-16. The pins allow the caliper to move in and out as the brakes are operated and as the brake pads wear. Since the calipers move on the pins, the bushings must be lubricated with high-temperature, waterproof disc brake caliper grease when they … Read more
