Narrative:
On rollout at 110 KTS; loss of braking noticed. Followed by ECAM showing loss of AC bus 1; blower fault and most important -- nosewheel steering. Accomplished QRH and ECAM; no recovery of AC bus 1 or nosewheel steering. Maintenance control called; told to pull circuit breakers M33; 34; 35; 36 to recover steering as aircraft was stuck on runway. Numerous resets attempted. Was finally able to recover nosewheel steering and exit runway.
