There’s nothing quite like the feel of brand-new Shimano brakes, but air bubbles and old fluid can quickly turn that "snap" into a "sponge." The EZMTB Shimano Specialized Bleed Kit (BK1021) is the complete, all-in-one solution designed specifically for the Shimano ecosystem.

Unlike universal kits, this package includes a dedicated bottle of high-performance Mineral Oil, so you don't have to go hunting for extra supplies. From Deore to XTR, or your favorite GRX gravel setup, this kit ensures a factory-perfect bleed every time.

Key Features

• Shimano-Specific Funnel & Plunger: Includes the iconic threaded funnel system for gravity bleeds at the lever—simple, clean, and highly effective.

• High-Performance Mineral Oil Included: Comes with a 60ml bottle of premium mineral oil, optimized for Shimano’s internal seals and high-temperature operating ranges.

   

   

• Ergonomic Syringe System: A high-clarity 25ml syringe with a secure-lock hose connector allows for precise "bottom-up" pressure bleeding.

• Universal MTB & Road Compatibility: Includes the standard M5 funnel thread for MTB levers and the necessary adapter for Shimano Road/Gravel (ST-series) hydraulic levers.

• Non-Corrosive & Safe: Mineral oil is much kinder to your bike’s paint and your skin than DOT fluid, making this the perfect "first-time" DIY maintenance kit.

Why the BK1021?

The BK1021 is the "Goldilocks" of bleed kits—it’s not a stripped-back basic kit, and it’s not an over-complicated workshop master set. It is specifically curated for the Shimano rider who wants a professional result without the professional price tag. Because it includes the oil, it’s ready to use the moment it arrives at your door.

Pro Tip: Shimano recommends bleeding your brakes at least once a season, or whenever the lever pull feels inconsistent. Regular maintenance prevents internal oxidation and keeps your stopping power predictable on steep descents.
