Loss of braking
(Source: A320 FCOM, 3.2.32, QRH 1.13)
If no braking available:
• REV MAX
• BRAKE PEDALS RELEASE
Brake pedals should be released when the A/SKID & N/W STRG selector is switched
OFF,since the pedal force or displacement produces more braking action in alternate
mode than in normal mode.
• A/SKID & N/W STRG OFF
Braking system reverts to alternate mode.
• BRAKE PEDALS PRESS
Apply brake with care, since initial pedal force or displacement produces more braking
action in alternate mode than in normal mode.
• MAX BRK
PR 1000 PSI
Monitor brake pressure or BRAKES PRESS indicator. Limit brake pressure to
approximately 1000 psi and, at low ground speed, adjust brake pressure as required.
If still no braking :
• PARKING BRAKE USE
Use short successive parking brake applications to stop the aircraft. Brake onset
asymmetry may be felt at each parking brake application. If possible, delay the use of the
parking brake until low speed, to reduce the risk of tire burst and lateral control difficulties.
