BRAKING SYSTEM
The aircraft braking system is differential, foot controlled braking system acting
on both wheels of the main landing gear through disk brakes.
Each brake calliper, on left and right hand wheels, is separately actuated by an
independent hydraulic line. There are interconnected Master Hydraulic Cylinder
fitted on the rudder pedals of the pilot and the co-pilot. By pushing the top of
the rudder pedal in order to rotate it, the Master Hydraulic Cylinder is actuated.
The pilot and copilot left brake pedals actuate the left wheel brake, and pilot and
copilot right brake pedals actuate the right wheel brake. Brake liquid tanks for
both, left and right hand hydraulic lines, are located behind the rudder pedals,
on top of the copilot Master Hydraulic Cylinders.
An intercept valve acts as a parking brake by stopping pressure relief.
For braking to be operational the brake intercept valve must be off and the brake
pedals activated. This can be activated by a dedicated brake handle in the
cockpit. The arrangement is apparent in the diagram below:
