Frequently Asked Questions
  • What are brake bleed nipples used for?

    Our stainless steel bleed nipples allow for precise venting of air and old fluid from brake and clutch systems. This helps prevent spongy pedal feel and ensures consistent hydraulic pressure.

  • What sizes are available for these bleed nipple fittings?

    We offer a range of bleed nipple thread sizes to suit most common brake and clutch systems:

    • M6 × 1.00
    • M7 × 1.00
    • M8 × 1.00
    • M8 × 1.25
    • M10 × 1.00
    • AN3 (3/8"‑24 UNF)

    These options ensure your new bleed nipples will be compatible with OEM and aftermarket components alike.

  • Are these brake caliper bleed nipples compatible with custom braided hoses?

    Yes, our bleed nipples are fully compatible with custom stainless brake lines and custom stainless clutch hoses, making them ideal for performance and modified applications.

  • What materials are these stainless steel bleed nipples made from?

    Each bleed nipple is CNC‑machined in the UK from high-grade stainless steel, offering superior corrosion resistance and structural strength under pressure.

  • Do these caliper bleed nipples require extra parts for installation?

    No additional parts are necessary. However, we recommend using a bleed nipple dust cover cap to keep contaminants out and extend service life.

  • How do I properly bleed brakes using a bleed nipple?

    Attach a clear hose to the bleed nipple, open it slightly, and pump the brake pedal or lever. Close the nipple before releasing the pedal. Repeat until only brake fluid flows out, free of air bubbles. Always monitor fluid levels in the reservoir during this process.
