R ACTION RESULT
R -------------------------------------------------------------------------------
R 1. Push in the two brake pedals on On the panel 400VU, the brake yellow
R the CAPT or F/O side. pressure triple indicator shows the
R left and right side pressure values.
R The pistons related to the Yellow
R hydraulic system are extended.
R 2. Release the brake pedals. The triple indicator shows that the
R pressure supplied to the brakes
R decreases to zero.
R The pistons related to the Yellow
R hydraulic system are retracted.
R 3. Slowly push the brake pedals on On the panel 400VU:
R the CAPT or F/O side. - the pressure supplied to the brakes
R increases in proportion to the
R pressure you put on the pedals,
R - the pressure shown at full pedal
R movement is between 870 psi (60 bar)
R and 1160 psi (80 bar).
R 4. Release the brake pedals
