Brake failure behind weekend-ending Fiore accident

Dean Fiore's Dunlop Series comeback has come to an abrupt end, with a brake failure confirmed as the reason behind his big Townsville crash.

The veteran racer, substituting for Jett Johnson at the NTI Townsville 500, crashed heavily towards the end of Saturday's Race 1.

AIM Motorsport has since announced Fiore won't compete on Sunday, with the #111 Ford Mustang suffering major damage in the crash.

The privateer squad also revealed Fiore, who walked away from the 150km/h impact, sustained a sore ankle.

"Dean was involved in a heavy crash towards the end of Race 1 today," the team communicated via social media.

"Dean is fine, however has a sore ankle and the 111 car won’t return tomorrow."

Several cars are also set for overnight repairs, with the cars of Brad Vaughan, Cooper Murray, Zach Bates, Campbell Logan, Jordyn Sinni and Cameron McLeod all damaged in a first-lap pile-up.

The race was won by Jack Perkins, with drivers finishing behind the bp pulse Safety Car following Fiore's crash.

The Dunlop Series take to the streets of Townsville tomorrow at 9:30am AEST for Boost Mobile Qualifying.
