Keith Andrews' Brentford side dropped points at home for the first time since October as Daniel Farke's side battled back for a draw at Gtech Community Stadium.
Jordan Henderson put the hosts in front with 20 minutes remaining, with Republic of Ireland goalkeeper Caoimhín Kelleher making a string of fine saves at the other end.
He could little, however, with Dominic Calvert-Lewin's 82nd minute equaliser, the striker heading from six yards from Gnonto Wilfried's cross.
Their three game winning streak at home at an end, Andrews admitted: "First half (we) controlled the game without creating too many clear-cut opportunities.
"Second half I thought they started really well, we had to dig in, had to suffer and came through. We made a couple of changes, got our noses in front and unfortunately weren't able to manage the game.
"Overall, I felt it was a team we faced that were in a good place.
"They have had some big performances and results lately, so we dust ourselves down, take the point and move on."
Ireland defender Nathan Collins also played the full 90 minutes for Brentford.
Leeds boss Farke, who pronounced himself happy with the point, was especially enthused by Calvert-Lewin, declaring him "one of the best English strikers in the Premier League.
"I have got such a good relationship with Thomas that I am far away from giving any recommendation.
"He will know exactly what he needs to win the World Cup, but it is for each player the same.
"If you deliver with consistency and not just one or two games, or a good week or a good month, this is not enough, but if you deliver with consistency, then each and every manager or coach in the world is aware and will be ready.
"Dominic has proven this before. He has many caps for England and has also a good goal record.
"I think these goals are even more remarkable for a promoted side that can't play that dominant than sides fighting for the title, so he will have chances to be in the spotlight.
"My relationship with Thomas is so close and he knows if he has any questions, he can call my number and we can speak about it. It always depends on the performances and I think (the) sky is the limit for Dominic.
"He was very unlucky in the last couple of years with injuries, but his quality was never in doubt and his CV speaks for itself.
"For me, he is one of the best English strikers in this league. Harry Kane is playing in Germany for Bayern Munich, but in the Premier League, he is definitely one of the best English strikers and he will be a key player for us going forward."
