Each multi rotor steel brake assembly is composed of one brake cylinder, one pressure-plate assembly with replaceable steel wear pads, two or more rotating discs (rotors) with sintered-friction material on a steel core, one or more stationary discs (stators) with replaceable wear pads, one torque-tube assembly with replaceable wear pads, along with necessary nuts, washers, and bolts.
Braking action begins to occur when hydraulic pressure is applied to the brake via the pilot’s or co-pilot’s master cylinders. As the hydraulic pressure reaches the brake it forces the pistons outward against the pressure plate assembly (with wear pads), which compresses the brake stack (rotors and stationary discs) against the torque tube assembly (with wear pads). This generated frictional force is transferred to the wheeltire through the rotors, which have drive slots to engage the main wheel, and thus slows the aircraft.
