Hydraulic Brake Bleed Kit — DOT

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

The BKD-1 Hydraulic Brake Bleed Kit will bleed most models of DOT fluid-based hydraulic disc brakes, including models made by SRAM®, Formula®, Hayes®, and Hope®. Bleeding of hydraulic brakes removes air bubbles and contaminants from the braking system, for long-lasting components and peak performance.

The BKD-1 is built for the rigors of daily commercial use, and includes two syringes, hoses with shutoff clips, multi-size bleed blocks 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.
