Addressing the press outside Downing Street, May acknowledged that a "significant number" of her MPs voted against her, but welcomed the outcome.
She insisted she would stay on to "finish the job" she has set herself as Prime Minister.
She said ousting her and holding a leadership vote - a process that could take weeks - could result in Brexit being delayed or even stopped.
Fellow seasoned Brexiteer Owen Paterson, who was said to have sparked this vote, shared his letter of no confidence in The Telegraph Tuesday night, writing that "the Prime Minister's proposed "deal" is so bad that it can not be considered anything other than a betrayal of clear manifesto promises".
Brady said the vote would be held in Parliament between 6pm and 8pm Wednesday (7am and 9am Thursday NZT), with the results announced soon after.
MP Peter Bone said it was clear she had failed to win a majority of backbenchers, pointing out that ministers and the "payroll vote" amounted to more than 150 MPs.
As investors and allies tried to work out the ultimate destination for the world's fifth-largest economy, rebel lawmakers in May's party said she had to go.
European Commission head Jean-Claude Juncker said: "The deal we achieved is the best possible".
He resigned his Cabinet position in July in protest over May's Brexit plan, which he denounced as too soft and has since then eviscerated her exit strategy in regular columns for the Daily Telegraph newspaper.
These two candidates are then put to a postal ballot of the wider Conservative Party membership.
Many Conservative politicians do not want May to lead the party into that vote, given her poor performance in the UK's 2017 poll.
She said Labour would table a no-confidence motion that all MPs - not just Conservatives - will be able to vote in when they felt they had a chance of winning it, and forcing a general election.
But in a last-minute pitch to her MPs before the vote she promised to stand down as leader before the next scheduled election in 2022. Now the PM's own party may sack her.
May, who spent Tuesday touring European Union capitals to appeal for changes to sweeten her divorce deal for reluctant United Kingdom lawmakers, has until January 21 to hold a vote on the agreement in Parliament, a timetable that could be scuttled if she is replaced.
A leadership vote had been triggered after 48 Conservative Party MPs had written letters expressing no confidence in her leadership - 15 percent of the party's members in the Commons.
"A Brexit that delivers on the vote that people gave, that brings back control of our money, our borders, and our laws, that protects jobs, security and the union, that brings the country back together rather than entrenching division".
One of her cabinet colleagues is predicting a "long day" but a "solid win".
"I will contest that vote with everything I've got".
Most of the county's MPs had publicly backed the PM, with the exception of Gravesham MP Adam Holloway, who had already been among MPs demanding a vote.
