Bike Brake Bleed Kit with Brass Adaptors and Funnel

For Hydraulic Brake Servicing

This Bike Brake Bleed Kit includes a syringe, funnel, clear hoses and brass adaptors for servicing compatible hydraulic bicycle brakes. Use it with your brake manufacturer’s bleed procedure to remove trapped air and replace brake fluid.

Air in hydraulic brake lines can cause a soft or spongy lever feel. A correct bleed can help restore firm, consistent lever action. However, bleeding will not repair worn pads, damaged seals or fluid leaks.

The Bike Brake Bleed Kit brings the main bleed tools together for home maintenance. Also, the supplied fittings cover several thread sizes used across bicycle brake systems. Check your exact brake model before choosing an adaptor.

Key Features

• Brass adaptors provide M4, M5, M6 and M7 connection options.
• Different adaptor lengths help accommodate varied bleed-port depths.
• Clear hoses let you watch fluid movement and air bubbles during bleeding.
• A translucent funnel holds fluid at a compatible lever connection.
• The syringe allows controlled fluid transfer during the approved bleed process.
• A hose clamp helps control flow when positioning or disconnecting the hose.
• Three differently shaped bleed blocks provide options for compatible calipers.
• The moulded stand keeps the funnel and adaptors together between jobs.

Benefits of This Bike Brake Bleed Kit

1. Maintain your brakes at home using the correct tools and manufacturer’s instructions.
2. Watch for trapped air through the clear hoses as you work.
3. Choose from several fitting sizes instead of relying on one brake-port connection.
4. Keep small adaptors organised on the supplied storage stand.
5. Prepare compatible road, gravel and mountain bike brakes for regular riding.

Bike Brake Bleed Kit Compatibility Guide

The supplied adaptors cover M4, M5, M6 and M7 bleed connections. The guide below lists brake systems that use these thread families.

Compatibility varies by brake model and connection point. Match the thread, adaptor reach and sealing arrangement to your brake’s service instructions. Use the specified brake fluid and keep mineral-oil equipment separate from DOT-fluid equipment.

For reference, M5 × 0.8 fittings serve selected Formula Cura, Tektro, Hayes and Nutt applications. M6 × 1.0 fittings also serve selected Promax and other systems. These thread associations do not guarantee that every fitting suits every model.

Shimano drop-bar funnel adaptors commonly use M7 × 0.75 connections. Applications include compatible Dura-Ace, Ultegra, 105, GRX and Tiagra levers. However, check the individual lever’s service instructions.

Before You Start

First, identify your brake model and its required fluid. Then check adaptor pitch, reach and seal placement. Never force a fitting into a bleed port.

Use only the brake fluid specified by the brake manufacturer. Also, confirm that the syringe, hoses and seals suit that fluid. Keep mineral-oil tools separate from DOT-fluid tools to prevent contamination.

Remove the brake pads and fit the correct bleed block before following the manufacturer’s procedure. Keep fluid away from pads and rotors. Finally, check for leaks and test brake operation before riding.

Frequently Asked Questions

Will this Bike Brake Bleed Kit fit every hydraulic brake?

No. The kit includes several fitting sizes, but some brakes need dedicated connectors. Match the exact brake model and bleed-port specifications.

Does an M6 adaptor fit every M6 bleed port?

No. M6 ports can use different thread pitches. Seal position and fitting depth can also differ.

Can I use it for Shimano brakes?

The kit includes M5 and M7 fitting options relevant to Shimano lever connections. Confirm the required fitting for your model.

Does this kit include a confirmed SRAM Bleeding Edge connector?

The supplied images do not establish that. Do not assume the threaded adaptors replace a dedicated Bleeding Edge connector.

Will bleeding fix all braking problems?

No. Bleeding addresses trapped air and fluid servicing. Inspect pads, rotors, hoses and seals when diagnosing poor brake performance.

Practical Tools for Routine Brake Maintenance

This Bike Brake Bleed Kit combines fluid-handling tools, brass fittings and bleed blocks in one organised set. Check compatibility first, then follow your brake manufacturer’s service procedure for the correct result.
