After seven years at WQBK, Brehmer left the position and moved to Chicago to work for WXRT as music director beginning in October 1984.

After completing a one-year contract at KTCZ-FM, Brehmer returned to Chicago's WXRT to serve as the morning D.J., replacing Terri Hemmert.

[12] In 2009, WXRT sent a mass email using Brehmer's name to subscribers, encouraging political action to lobby Congress regarding music royalties.

Each year, Brehmer wrote just under a hundred essays, and he stated that in total he had written approximately 1800 pages of Lin's Bin.

[6] Brehmer announced on the air on July 12, 2022, that he had prostate cancer and was taking a leave of absence from WXRT to undergo chemotherapy.

Brehmer died on January 22, 2023, and his death was announced to WXRT listeners that morning by his long-time colleague Terri Hemmert.

Brehmer was memorialized in a WXRT broadcast, January 23, 2023, hosted by Terri Hemmert, Marty Lennartz, Johnny Marrs, Frank E. Lee, Ryan Arnold and Annalisa.
