Harley-Davidson bikes investigated for brake failure
The National Highway Traffic Safety Administration (NHTSA) is investigating the anti-lock braking system on 430,000 Harley-Davidson motorcycles after receiving complaints about brake failures.
Forty-three riders have reported their brakes failed without warning, the Associated Press reported. The NHTSA has received three reports of crashes and two reports of injuries involved with brake failure.
The bikes under investigation are those from model years 2008-11 with ABS brakes.
A possible cause for the failure may be that some riders didn’t change their brake fluid every two years, as recommended. Old fluid can corrode the valves in the ABS system.
