Bleedkit.com Premium Gold Magura MT Bleed Kit

Magura's MT family does not bleed like a Shimano. The lever uses a Luer-slip funnel that twists and clicks home rather than threading in on an M5 brass cone. The caliper port takes an M6 fitting that wants its own purpose-built tube, not a Shimano flat-bar block jammed in sideways. And the fluid is mineral oil, the same broad chemistry as Shimano's mineral oil but compatible with the Magura MT seal stack the brake system is engineered around. Every piece in the Premium Gold Magura MT Bleed Kit matches that interface, with 100 ml of Bleedkit.com's Gold mineral oil included so the bleed runs without sourcing the fluid separately.

What's in the kit

The lever-side syringe is 20 ml with a special plug sized to the Magura MT master cylinder. The caliper-side syringe is 20 ml with an M6 fitting and a long-lasting tube that seats into the Magura caliper port. The bleed blocks (two in the kit) are sized to the Magura MT caliper geometry. The Torx T25 wrench handles the lever-side bleed-port hardware, and a velcro strap secures the caliper syringe to a fork leg or chainstay during the bleed. The fluid included is 100 ml of Bleedkit.com's own Gold mineral oil, formulated for ultra-high-performance use in mineral-oil brake systems.

Compatibility

The kit fits every Magura MT brake currently in production: MT8 SL, MT8 Pro, MT7 Pro, MT5, MT4, MT4 FM, and the MT Trail family. It is mineral-oil only and will not service Shimano (different funnel pattern), SRAM (DOT fluid), or Formula Cura (Cura-specific port). For a workshop with Magura on the rotation alongside Shimano or Tektro / TRP, the Workshop Master Mineral Oil kit consolidates Magura + Shimano + Tektro into one box; this kit is the dedicated Magura-only answer.

Built in Ljubljana, since 2011

Bleedkit.com has been building system-specific kits in Ljubljana, Slovenia since 2011, distributed in North America by Euro Toolworks alongside the Unior cycling-tool catalog. Unior has been forging hand tools in Zreče since 1919, and is the official technical partner of multiple World Tour and downhill teams. The Magura MT kit is the one Bleedkit.com SKU that ships with fluid in the box: 100 ml is enough for several complete bleeds, and the Gold formulation is what the kit's hardware was tested against rather than a generic mineral oil from another bottle.

Pro tip from our mechanics

The Luer-slip funnel on a Magura MT seats with a quarter-turn click rather than a screw-down thread. The right feel is firm engagement with no rotational play once the click sets; if the funnel rocks, the seal isn't holding and the bleed will pull air through the joint instead of out of the caliper. Test the seat by pressing down on the funnel before the fluid goes in; a clean seat stays put under thumb pressure.
