The Park Tool BK-UK - Hydraulic Brake Bleed Kit Upgrade Kit is designed to enhance your existing Park Tool BKD-1 and BKM-1 kits. This upgrade kit includes six new and improved components, ensuring compatibility with the latest brake models from leading manufacturers.

What's Included:

• Part #2600A (x2) - M4 x 0.8 adapter for use with SRAM® DB8, Trick Stuff® and other mineral oil brake systems
• Part #2588.2 - Thin-walled hose compression sleeve for internal bleed nipples, suitable for Shimano® mineral oil brake systems
• Part #2574A - Hose assembly with integrated fitting for bleed nipples, ideal for Shimano® mineral oil brake systems

It's important to note that each part's seals are designed for a specific type of fluid, either DOT fluid or mineral oil. They should only be used with the systems they are intended for. Mixing DOT fluid and mineral oil in the brake system or service tools can lead to cross-contamination, potentially causing seal failure and brake failure.
