Indu Chaudhary opened India's account with a bronze in the 44kg weight category in the female section, but after that only Pradeep managed a medal, in the boy's segment.
Pradeep (50kg) started with a loss in the freestyle category before clawing his way back in the repechage round to win India its second bronze from the championship.
The 21-year-old was no match for Ruslan Surkhayev, losing the first period 0-1 and then succumbing 2-6 in the next, to hand his Azerbaijan opponent a comfortable victory.
However, Surkhayev's charge to the finals gave Pradeep a chance to compete in the repechage round and the Indian grappler made full use to finish in the medals column.
Pradeep beat Germany's Marc Luithle 3-0 before overcoming Muammer Sancak of Turkey in the bronze medal bout.
After clinching the first period on a level score of 1-1, the Indian toiled to take the next one 4-3 and eke out a win.
