Alleged subway brake-yanker Isaiah Thompson was hauled into Manhattan criminal court Friday, where prosecutors tried to bring a screeching halt to the stalling spree with a request for $25,000 bail.

As his mom looked on from the gallery, Thompson, 23, was arraigned on charges of criminal tampering, reckless endangerment and public lewdness, for which he was arrested late Thursday outside his Brooklyn home.

His defense attorney Eliza Orlins called the $25,000 figure “excessive and unfair” and bail was ultimately set at $10,000 bond or $5,000 cash.

Thompson, who donned a black sweatshirt and jeans for his court appearance, purportedly told cops after his arrest that he likes to “create mayhem” and “inconvenience people,” sources told The Post earlier.

His public lewdness charge stems from a May 16 incident in which Thompson allegedly hung outside a northbound B train — as it was traveling between 8th Avenue and West 14 Street — and exposed himself to passengers on the platform.

The young man was still being held in Manhattan on Friday evening, waiting for his mother to post his bail.
