Federal Investigators are examining ABS brake failures in Harley Davidson models 2008 through 2011 which have caused crashes and injuries. The NHTSA says as many as 430,000 motorcycles may be affected.
According to the National Highway & Traffic Safety Administration (NHTSA), there appears to be a problem with ABS brake systems in Harley Davidson motorcycles from 2008 to 2011. More than 400,000 bikes may be affected and the investigation may find other models of bikes also have the same problem.
According to Revzilla motorcycle magazine, the problem has to do with brake systems using hygroscopic fluid, stating, “Most brake fluid (the exception is DOT 5) is hygroscopic, meaning it absorbs moisture from the air. In their response, Harley claims that the moisture found in old, contaminated brake fluid can damage the actuator valves found in the anti-lock braking system. It is unclear at this time as to whether it was the anti-lock functionality of the system that failed or the entire braking system itself.”
The NHTSA reports that Harley-Davidson has responded that some owners may not have had their brake fluid changed every two years according to manufacturer’s suggested or required maintenance.
