But the report makes it sound like the alternate brakes were being used but not slowing the aircraft down very much.

"At 064506 UTC, • Max brake pedals deflection was reached after 08 sec. • The deceleration progressively increased and stabilized between +0.2g and +0.25g. • The ground speed decreased from 145kt to 125kt. As there was ECAM message of “Break Auto Break Fault” during landing, aircraft was on alternate braking, brake pedal order commanded alternate braking pressures. However the deceleration experienced by the aircraft remained low (between +0.2 and +0.25g) despite max brake pedal application.

From 064506 UTC after touchdown to 064517 UTC, the brake pedals were maintained to full deflection while aircraft deceleration remained constant. As a consequence, the ground speed continued to decrease regularly from 125kt to 76kt.

At 064517 UTC, the anti-skid was turned off as per Abnormal and Emergency procedures. Aircraft continued to decelerate. "
