Every mineral oil brake system uses different bleed port fittings, which means bleeding Shimano brakes requires different hardware than bleeding Magura or Campagnolo. Park Tool's BKM-1.2 Hydraulic Brake Bleed Kit consolidates the adapters for all of them into one case. The kit covers Shimano, Magura, TRP, Tektro, Trick Stuff, SRAM DB8, Campagnolo, Promax, and Clarks mineral oil systems, with threaded adapters sized to each brand's bleed port specifications. If you're working on your own bikes or handling service for riding partners with mixed brake setups, you won't need to source brand-specific bleed kits separately.

The kit includes 2 20ml syringes with removable handles and plungers, hose assemblies with shutoff clips that prevent fluid from draining back during the bleed process, and a bleed funnel with stopper for systems that use gravity or funnel-based bleed procedures. Brand-specific adapters cover the range: M7 x 0.75 threading for Shimano, M6 x 0.75 for Magura, M4 x 0.7 for SRAM DB8, Trick Stuff, and Campagnolo, and M5 x 0.8 for Tektro and Formula Cura, among others. One hose assembly features an integrated fitting with a guide needle designed specifically for Shimano bleed nipples, and a separate open-ended hose handles calipers that bleed directly to a disposal bag.

Bleed blocks come in 2 configurations: dual-sided 10mm/12mm blocks and dedicated 11mm blocks, so you can match the block to your caliper's piston spacing. These hold pistons apart while the system is open, keeping pads clean and preventing pistons from extending during lever pulls. The kit also includes 2 adjustable syringe holders that strap to the fork leg or seatstay, freeing your hands during the bleed process instead of having someone hold syringes upright for you....
