Brimmerton was bred, raced and owned by American Quarter Horse Hall of Fame member Bobby D. Cox of Fort Worth, Texas. He was foaled on February 15, 2001.

Sired by all-time leading sire and American Quarter Horse Hall of Fame stallion First Down Dash, Brimmerton was out of the Ronas Ryon mare Fitting Celebration, and was named in honor of the cruiser that Cox served on in the Navy.

Cox, a multiple-time champion breeder, has been quoted as saying the stallion was his favorite horse.

After qualifying to two Grade 1 futurities in his first season at the track, Brimmerton found his stride as a sophomore and clipped off wins in the Bayer Legend Texas Derby Challenge (G3), Rainbow Derby (G1) and All American Derby (G1). He would retire at the end of 2004 with seven wins from 12 starts and earnings of $519,538. He was named champion 3-year-old colt.

As a sire, he got the winners of more than 480 races and horses that earned more than $5.9 million. His foals also earned AQHA performance points. Among his runners were the likes of King Brimmerton ($348,698), Brimmies Alli Bi B ($221,154) and Count De Monet ($200,894).

He is also the sire of stakes sire Brimmstone.
