b.
Brake control valve: supplies HYD 1 hydraulic
pressure to operate wheel brakes whenever the
brake pedals are depressed, the parking brake is
engaged, or upon command from the de-spin

Anti-Skid System Block
c.
Anti-skid control valve: when a rapid wheel decel

is sensed, routes HYD 1 hydraulic pressure to
system return to prevent a tire skid
d.
Brake unit: transmits HYD 1 hydraulic pressure
into mechanical energy required to stop rotation
of main gear wheels
