Ramdin scored 59 off 40 deliveries, while Bravo's 45 came off 49 balls as they combined beautifully to rescue Trinidad from a precarious position.
Trinidad skipper Ramdin's decision to bat after winning the toss backfired as the Caribbean outfit lost its first three wickets -- William Perkins, Lendl Simmons and Adrian Barath-- for just eight on the board.
But Bravo and Ramdin rose to the occasion and saved Trinidad from the humiliation with the crucial fourth wicket stand that came off just 73 balls.
The highlight of Trinidad's innings was the partnership between Bravo and Ramdin. Sensing the urgency of the situation, both the batsmen started cautiously but opened up as the innings progressed.
While Ramdin was at his attacking best, Bravo played the second fiddle in the partnership.
Just when it was time for the Caribbean duo to accelerate, Yorkshire made a comeback with two quick wickets.
Bravo was the first to depart, holed out in the deep by Gary Ballance off leg-spinner Adil Rashid and then a ball later new man in Jason Mohammed fell victim to an unnecessary mix-up with Ramdin.
The dismissals, however, had little effect on Ramdin as he brought up his first Twenty20 half century with a four.
But Ramdin's terrific innings finally came to an end in the most unfortunate manner. Turning for the second run, he lost his footing and was run out after Kevon Cooper sent him back.
For Yorkshire, left-arm pacer Ryan Sidebottom starred with the ball registering figures of three for 13 from his four overs.
