Shimano BR-002 油壓碟煞注油漏斗 ROAD

Bleeding my road brakes used to mean a mess of spilled fluid, but this funnel's integrated design changed that completely—the oil flows straight through without a single drop escaping. Took me about ten minutes to finish the whole job, and the clear tube let me spot every air bubble as it rose.

The clear reservoir on this funnel makes it easy to see when the system is fully bled, and the integrated tube prevents messes on the frame. Really took the guesswork out of my first brake service.

The funnel fits snugly onto the brake lever, which made the bleeding process much less messy than using a makeshift setup. I've only used it once so far, but it seems well-made for the price.
