AIRCRAFT MAINTENANCE MANUAL
The master cylinder piston is actuated by
the push rod, which is in turn actuated by a
mechanical linkage to the rudder pedal
(Ref. Fig. 3-2). Pushing the toe of the
rudder pedal actuates this mechanism,
moves the piston, and thereby forces
hydraulic fluid into the hydraulic line to the
wheel brakes. The piston is returned by a
spring so that hydraulic pressure is
maintained only while the toe brake is
depressed.

Hydraulic fluid reservoirs should be kept at
least half full. If brake "sponginess" is
experienced, check the master cylinder
reservoir first. If it is empty or nearly
empty, it should be filled and the brake
system bled.
The master cylinders also have a lever
which locks the push rod in place to hold
the parking brakes on.
