The aircraft was landing on Cardiff's Runway 30. On finals, the Electronic Centralized Aircraft Monitoring (ECAM) display showed a STEERING caption and the crew cycled the A/SKID & N/W STRNG switch in an attempt to reset the Brake and Steering Control Unit (BSCU). The indications were that it was successfully reset but after touchdown the aircraft did not decelerate normally. The commander pressed the brake pedals to full deflection without effect. He then selected maximum reverse thrust and the co-pilot cycled the A/SKID & N/W STRNG switch. The commander again attempted pedal braking, without effect, and the crew selected the A/SKID & N/W STRNG switch to OFF. The commander then braked to bring the aircraft to a halt about 40 metres from the end of the runway, bursting three mainwheel tyres. There was no fire and the passengers were deplaned on the runway through the normal exit doors.
