The Wheel Brake Assembly (WBA) is a Dual Cavity unit.
The WBA is suitable to be a part of the Main Landing Gear Brake System to generate the braking torque
necessary to control, reduce and stop the wheel speed of the A/C on ground operation and to sink the
heat generated by the braking application.
The WBA is hydraulically powered and is installed inside each MWA of the A/C. Each brake includes
eight pistons, four for each braking line that produce a force normal to the friction surface that in turn
yields a braking torque to the main wheel. The WBA automatically adjust for wear without a
maintenance action after each braking action. The WBA matches with the MWA by means of nr.3 Rotor discs.
