A mobster who threatened to beat up two men to collect on an unpaid loan at the behest of a Luchese crime-family captain pleaded guilty to two counts of extortion in Brooklyn federal court on Wednesday.

Daniel Capra, 58, along with his brother Michael Capra, 52 — who pleaded guilty on Friday — were told by reputed mob boss Carmine Avellino to rough up two men to collect the $100,000 he lent them.

The criminal collection efforts took place in Brooklyn and Long Island in 2010. One of the men beaten up was 71 years old.

Capra read a statement in court Wednesday admitting to pressuring the two men, sounding like he was reading from a wiseguy handbook.

“In early 2010, in Brooklyn and Long Island, I agreed with my brother, Michael Capra , and Frank Bruno to pressure Angelo Paccione — who had vouched for Charlie Giustra — to get Paccione or Giustra to repay the money that Frankie Bruno or others had given to Giustra,” the aging tough guy said.

“In furtherance of that agreement, I told Michael Capra to shake up Paccione to get repayment.”

Daniel Capra faces between 2¹/₂ to 3 years when he is sentenced on Dec. 6.

Avellino faces extortion charges. His trial is set for Aug. 22.
