No, this kit is built specifically for Shimano's mineral oil hydraulic system and is not compatible with DOT fluid brakes such as SRAM or Avid. Mixing mineral oil and DOT fluid can damage seals in either system, so always confirm your brake's fluid type before bleeding, and use this kit only on Shimano or other mineral-oil-based brakes.

One syringe filled with mineral oil connects at the caliper bleed port while the other connects at the lever, and you gently push fluid through from one end while drawing it from the other to flush out trapped air bubbles. The metal master cylinder attachments seat securely onto the lever body to prevent leaks during this process, and the piston blockers keep the caliper pistons from popping out while the system is open.

This kit provides the tools and attachments for bleeding, and you will need Shimano-compatible mineral oil separately to actually perform the bleed. LeBycle's own mineral oil for hydraulic brakes pairs well with this kit for a complete at-home bleed setup.

Bleeding Shimano brakes at home is a very achievable job for a careful home mechanic, and this kit's guided attachments make the process considerably easier than improvising with generic syringes. It is worth having on hand if you ride regularly, since brake feel gradually softens over time and needs periodic bleeding, especially after long descents in hilly parts of India.

Most riders bleed their hydraulic brakes once or twice a year, or as soon as the lever starts to feel spongy or the bite point moves noticeably closer to the bar. Riders who do a lot of steep descending or ride in hot conditions may need to bleed a little more often, since heat can introduce tiny air bubbles into the fluid over time.

Yes, this is a genuine kit sold through DoGoodCo with CNC-machined metal master cylinder attachments built to seal reliably across repeated bleeds. If any component arrives damaged or faulty, our support team will help arrange a replacement as per store policy.
