disc brake [2]
Braking mechanism comprising a disc attached to the wheel, whose rotation is slowed down when the brake pads exert friction on it.
disc
Round plate interlocked with the wheel whose rotation slows down as it is braked by the friction of the brake pads.
caliper
Viselike part comprising a piston, which straddles the brake disc and supports the brake pads.
brake line
Tube carrying the brake fluid, which becomes pressurized when the driver steps on the brake pedal.
piston
Part put into motion by hydraulic pressure, which pushes the brake pads to squeeze the disc.
brake pad
Metal plate that is held by the caliper; it is covered with a heat-resistant material that rubs against the disc to slow down its rotation.
