If you don't want your rides to end poorly, then ensuring brakes are bled properly is bloody important. Shimano's TL-BT03 Professional Disc Brake Bleed Kit includes all of the necessary bits you'll need to make sure contaminated brake lines don't throw you off your own lines. In addition to the standard syringe and hose, it includes a clamp, funnel adapter, clear funnel, pedestal, and clear draining catch bottle. It works with both the current brake models and the older, open bath versions.
