Narrative:

Mechanic Y and I; inspector X; had changed a brake assembly; bled the brakes; reinstalled the main wheel assembly and returned aircraft to service. Everything maintenance wise was normal. Jacked aircraft; removed tire air pressure; removed wheel assembly; disconnected brake line and capped. Removed brake assembly installed new o-rings on all fittings; installed brake assembly; bled brake and closed all openings. Reinstalled the main wheel assembly; torqued; installed cotter pin and re inflated tire to 102 psi. Lowered aircraft and proceeded to finish paperwork. I saw that the brake line was installed. I was probably distracted for a moment by another mechanic's question and don't recall seeing the brake line torqued. The main wheel (mw) task card really should have the brake line 'not' removed; when changing the two o-rings in the swivel assembly. It is still accessible by extending back the brake line to gain access to the o-rings.
