Bleed hydraulic bike brakes

draft · verifying asked 185 ways distilled today
  1. 1

    Match the fluid to the brake.

    Mineral oil for Shimano and Magura, DOT for SRAM. Swapping them destroys the seals, quietly.

  2. 2

    Set the lever level and open the system.

    Bars rotated so the lever cup sits flat, bleed cup on top, syringe at the caliper.

  3. 3

    Push fluid up from the bottom.

    Bubbles rise: feeding upward chases them naturally to the cup at the lever.

  4. 4

    Flick and tap the line.

    Tap the caliper and hose while pushing. Stubborn bubbles cling to fittings until vibrated free.

  5. 5

    Close up, clean everything, test hard.

    Seal, wipe every drop off pads territory, pump the lever firm, then test-stop in the yard, not in traffic.

#1 becomes the Core. This atoma is young: submit a better distillation and take the seat.

No gear needed. Your pot, a timer and ice are enough. That is the point.
