Brady struck in Hull's 3-0 friendly win over Liverpool on the weekend.
The rookie says the success of close friends James Chester, Cameron Stewart and Corry Evans at the KC Stadium last season is providing him with inspiration.
"Seeing what the other lads have done here gives me a lot of confidence," Brady told the Hull Daily Mail.
"Every one of them has done well and fitted in as well as the lads that have been here for a few years."
"Hopefully I can be the same. I've only been here a week but it feels like months already.
"This is massive for me. It's my first loan away from United and my first home game here is in front of 20,000. It's brilliant.
"To be involved in games that mean so much more than reserve games is something I'm really looking forward to this season. I can't wait for it to start now."
