Hydraulic Brake Bleed Kit — Mineral

The BKM-1 has been discontinued and replaced by the BKM-1.2.

The BKM-1 Hydraulic Brake Bleed Kit will bleed most models of mineral oil-based hydraulic bicycle disc brakes, including models made by Shimano®, Magura®, Clarks®, Promax®, Tektro®, and TRP®. Bleeding of hydraulic brakes removes air bubbles and contaminants from the braking system, for long-lasting components and peak performance.

The BKM-1 is built for the rigors of daily commercial use, and includes two syringes, hoses with shutoff clips, multi-size bleed blocks, a bleed funnel, and a unique attachable syringe mount, as well as multiple hose fittings to fit the multiple standards found on hydraulic bicycle brake systems. Every part is replaceable and available from Park Tool. Housed in a rugged storage case.
