Disgraced carpenters union shop steward Michael Brennan was slammed with a five-year prison sentence yesterday, despite his apology to a judge.

“I will strive through acts of contrition to help those less fortunate,” Brennan, 54, the former shop steward of the carpenters union Local 608, groveled to Manhattan federal Judge Victor Marrero. “I beg for forgiveness. I stand before you a broken man.”

Brennan has admitted to racketeering after he was accused of embezzling union funds, taking bribes and destroying documents.

He was part of the larger scandal that ensnared District Council of Carpenters chief Michael Forde.
