I’ve never been ask this question, but I was curious how you know if you’re under Federal investigation?
In Harley-Davidson’s case it might have been a knock on the door of the Milwaukee HQ.
A common motorcycle maintenance task is to replace the hydraulic fluid in the brake system. Check your service manual, but for many Harley-Davidson models it’s recommended to change the D.O.T. 4 fluid and flush the brake system every two years.
Did you know brake fluid can collect condensation over time from the outside air? Brake fluid collects water in a similar fashion as your McDonald’s soda cup has water droplets on the outside. Hydraulic fluid will over time absorb water which causes the fluid to boil when the brakes are applied and will reduce effectiveness of the system. A spongy brake feel might be a combination of contaminated brake fluid or air in the system. Either way, changing the brake fluid is often recommended.
But, I’ve digressed. Motorcyclists have reported that the brakes on the hand lever and foot pedal did not work, causing one driver to crash into a garage door.
Harley-Davidson stated it was aware of the Federal investigation and that it was cooperating with regulators.
