Meonum Brake Bleeder Kit — 2‑Set 100 ml Syringes with One‑Way Valve Hoses (50 cm)

Meonum 2 Set One Way Brake Bleeder Kit is a complete replacement and maintenance kit for bleeding hydraulic disc brakes and clutches, including two 100 ml syringes, two one-way valve hoses (50 cm), valve clamps and sealing tape.

Whether you're servicing mountain bikes, motorcycles, ATVs or passenger vehicles, this Meonum kit provides the parts needed to evacuate air and extract fluid cleanly from hydraulic brake systems. The package combines one-way check valves to prevent backflow, clear flexible hoses sized for common fittings, 100 ml syringes for controlled fluid movement, and small accessories to secure fittings and keep contaminants out. It’s designed as an economical, ready-to-use replacement when factory hoses or tools wear out or when you need a portable kit for field servicing.

How does the one-way valve help when bleeding brakes?

The integrated one-way check valve prevents brake fluid or air from returning into the caliper during extraction, making single-person bleeding simpler and cleaner. It reduces the chance of introducing new air while you pump fluid out and helps maintain a consistent flow direction during the procedure.

• One-way valve length ~2.2 inches to mate with common bleed nipples.
• Prevents backflow and cross-contamination of fluid.
• Use tape on threaded end to seal and block dust ingress.

What components are included and what sizes should I expect?

The kit contains two 100 ml syringes, two 50 cm (19.7 in) flexible oil fluid hoses with one-way valves, valve clamps and sealing tape for the small ball bearing. Dimensions are chosen to fit most motorcycles and many vehicles, but always confirm compatibility before installing.

• Total hose length: 19.7 inches (50 cm) for reach and leverage.
• Large tube ID ≈ 0.2 in (outer diameter 0.31 in); small tube ID ≈ 0.14 in (outer diameter 0.2 in).
• Syringes: 100 ml capacity for precise fluid control.

Can this kit remove air bubbles and handle different fluids?

Yes—this kit is built to evacuate trapped air from hydraulic brake lines and can be used with various compatible fluids where the materials are safe. While primarily intended for brake and clutch hydraulic fluids, the durable hoses and syringes can also be used for other non-corrosive liquids in maintenance tasks.

• Designed to extract air pockets efficiently from brake circuits.
• Suitable for DOT fluids and many common hydraulic brake oils—check fluid compatibility first.
• Also usable for fuel-transfer tasks in non-pressurized situations (verify chemical compatibility).

How do I prevent leaks and protect small parts during use?

The kit includes tape and a valve clamp to secure threaded connections and capture the small ball bearing inside the valve, preventing loss and contamination. Proper sealing and clamping minimize fluid loss and keep the bleeding session tidy.

• Wrap tape on threaded valve ends to block air and dust entry.
• Valve clamp holds hoses and stops dripping during disassembly.
• Clear hoses let you watch fluid color and bubble movement in real time.

Who this is for: The Meonum 2 Set One Way Brake Bleeder Kit is aimed at DIY mechanics, bike and motorcycle riders, small repair shops and hobbyists who need an affordable, portable bleeding solution. It’s ideal if your current hoses or syringes are worn, if you want a spare set for field repairs, or if you require a straightforward single-person bleeder that reduces mess and simplifies air removal. Always verify hose and valve dimensions against your vehicle’s bleed nipple before purchase and follow manufacturer guidance for fluids and procedures.
