It took only one lap of practice for Trevor Bayne's Daytona 500 momentum to wear off.
Bayne crashed on the first lap of practice at Phoenix International Raceway on Friday afternoon, hitting the wall hard following what he said was a brake failure on his No. 21 car.
"On pit road, I told them the brakes felt like they weren't working right," he said. "I paced myself getting into the corner and the brakes just never worked. Even down the backstretch, I was playing with them, trying to get them dialed in, but I got off into the corner and they just never worked, never slowed down."
Bayne said by the time he figured out the brakes weren't working at all, it was too late.
"When I went into the corner, as soon as I let off the gas I knew it was crashing, because I just wasn't going to slow down," he said. "And it happened. Not much I could do there. ... I don't know why the brakes weren't right there."
The team has already pulled out its backup car. His crash-shortened 98.047 mph lap has put him last on the speed charts for the first practice.
