_____________________________________________
1. General
_______
A. Tires, Wheels, Brakes The main gear wheels have multidisc carbon brakes that two sets of independently supplied pistons operate; the Green hydraulic system supplies one set, the Yellow hydraulic system supplies the other set with the aid of one brake Yellow pressure accumulator. Each brake has automatic adjusters, two wear pin indicators and a temperature sensor. The main gear wheels include fusible plugs which protect the wheel and the tire against burst if an overheat occurs. The wheels have radial tires.
