2015 KTM450SX-F Rear Brake Bleed/2008 KX500AF (Aluminum Frame) 10-02-2020

The Brembo rear brake master cylinder cap on KTM, Husky, Beta and a few other brand motorcycle's will often corrode behind the O-ring where you can't see it. This will eventually cause air or moisture to enter causing a spongy or failed rear brake system.
