HYDRAULIC BRAKE BLEED KIT DOT FLUID PARK TOOL BKD-1.2

The Park Tool BKD-1.2 is the hydraulic brake bleed kit for DOT fluid, designed to service most DOT fluid-based bicycle hydraulic disc brakes, including SRAM, Formula, Hayes and Hope models. Bleeding removes air bubbles and contaminants from the system, helps components last longer and restores full braking performance.

The kit is built for heavy commercial use and comes in a rugged case, so every accessory stays organised and protected between jobs. It contains two 20 ml syringes with hoses fitted with shutoff clips, bleed blocks, adjustable syringe holders and a set of threaded adapters to connect to different levers and calipers. Every component is available as a Park Tool replacement part, so the kit stays in working order even with daily workshop use.

How to use the DOT brake bleed kit

• Bleeding levers and calipers on DOT fluid hydraulic systems, with two syringes to work on both ends of the system.
• Shutoff clips on the hoses let you control fluid flow and avoid drips when connecting and disconnecting.
• 10/12 mm universal bleed blocks and 11 mm bleed blocks for Hayes systems keep the pistons in place during the job.
• Adjustable holders support the syringes and keep your hands free during the most delicate steps.
• The SRAM Bleeding Edge fitting and the M5 x 0.8 and M6 x 1.0 adapters cover the main bleed ports.

Why choose Park Tool BKD-1.2

• One kit for most DOT fluid hydraulic brakes, without buying a different kit for each brand.
• Built for professional workshops: components suited to heavy use and a rigid case to store and carry everything.
• Replacement parts available individually: hoses, O-rings and syringes can be replaced without changing the whole kit.
• Dedicated exclusively to DOT fluid: Park Tool advises never mixing DOT fluid and mineral oil, either in the system or in the tools, because cross-contamination can damage seals and compromise braking. For mineral oil systems there is the dedicated Park Tool BKM-1.2 kit.

The Park Tool BKD-1.2 hydraulic brake bleed kit for DOT fluid is the right tool for clean, repeatable bleeds on SRAM, Formula, Hayes and Hope brakes, in the workshop or in your home garage. Brake fluid is not included.
