What's Included in the BKM-1.2 Mineral Oil Bleed Kit?

The Park Tool BKM-1.2 is a complete hydraulic brake bleed kit formulated for mineral oil brake systems, including Shimano, Tektro, and other mineral oil-compatible hydraulic disc brakes. The kit includes bleed syringes, tubing, fittings, and mineral oil bleed fluid to perform a full brake bleed from reservoir to caliper without sourcing components separately. Each part is sized and connected to work together in a clean, controlled bleed that purges air from the system and restores full lever feel and modulation.

Hydraulic brakes lose performance gradually as air enters the system through normal use or temperature cycling, and a proper bleed restores the firm, predictable feel that disc brakes are known for. The BKM-1.2 gives you everything needed to do the job correctly at home or in a small shop environment without needing a full professional brake bleed station.
