Do you know how B787 break works?
Unlike other Boeing aircrafts, the 787 brakes are NOT hydraulically operated. Instead, they’re electric! CCD So how exactly does that work? Each Main Landing Gear wheel has 4 Electric Brake Actuator (EBA) which control the application of braking force onto the carbon disc. So for 8 wheels, that’s a total of 32 EBAs. The 32 EBAs are in turn controlled by 4 Electric Brake Actuator Controllers (EBACs) where one EBAC controls one fore-aft wheel pair.
In electric braking systems, the conventional hydraulic equipment is replaced by electronic control units and hydraulic pistons replaced by electromechanical actuators. The introduction of electric brakes is an advance on a par with the introduction of carbon brakes some 30 years ago, and paves the way for even “more electric” aircraft.
