5. Setup and Installation
Proper installation of the bleed screws is crucial for the safe and effective operation of your bicycle's hydraulic brakes. If you are unsure about any step, it is recommended to consult a professional bicycle mechanic.
Tools Required (Not Included):
- Appropriate Torx wrench (for the bleed screw head)
- Brake fluid (compatible with Magura EBT systems)
- Bleed kit (syringe, hose, collection bottle)
- Clean rags
- Safety glasses and gloves
Installation Steps:
- Prepare the Work Area: Ensure your bicycle is stable and the brake lever is accessible. Protect painted surfaces from brake fluid spills.
- Locate the Existing Bleed Screw: Identify the bleed screw on your Magura EBT brake oil tank.
- Remove the Old Bleed Screw: Carefully unscrew the existing bleed screw using the appropriate Torx wrench. Be prepared for a small amount of brake fluid to escape.
- Inspect the New Bleed Screw and O-ring: Ensure the new GIYO bleed screw and its O-ring are clean and free from defects. The O-ring is essential for creating a proper seal.
- Install the New Bleed Screw: Gently insert the new GIYO bleed screw with its O-ring into the brake oil tank. Hand-tighten it initially.
- Tighten the Bleed Screw: Using the Torx wrench, tighten the bleed screw to the manufacturer's recommended torque specification for your Magura EBT system. Do not overtighten, as this can damage the brake tank or the screw.
- Perform Brake Bleeding (if necessary): If air has entered the system or if you are replacing fluid, proceed with the standard Magura EBT brake bleeding procedure as per your brake manufacturer's instructions. The new bleed screw will function as the access point for this process.
- Clean Up: Wipe away any spilled brake fluid immediately with clean rags. Dispose of brake fluid responsibly.

6. Maintenance
Regular maintenance of your bleed screws and brake system will ensure optimal performance and longevity.
- Regular Inspection: Periodically check the bleed screws for any signs of leakage, corrosion, or damage.
- O-ring Condition: The O-ring provides the seal. If you notice any fluid leakage around the bleed screw, inspect the O-ring for cracks, hardening, or compression. Replace the O-ring if it shows signs of wear.
- Cleaning: Keep the area around the bleed screw clean to prevent dirt and debris from entering the brake system during maintenance.
- Bleeding: Bleed your brakes according to your bicycle manufacturer's recommendations or whenever braking performance feels spongy or inconsistent.
7. Troubleshooting
Here are some common issues and their potential solutions related to bleed screws:
| Problem | Possible Cause | Solution |
|---|---|---|
| Brake fluid leakage around the bleed screw | Loose bleed screw, damaged O-ring, incorrect O-ring size. | Ensure the bleed screw is tightened to the correct torque. Inspect and replace the O-ring if damaged or incorrect. |
| Brakes feel spongy after bleeding | Air still present in the brake system. | Repeat the brake bleeding procedure carefully, ensuring all air is expelled. Check for leaks around all connections. |
| Difficulty unscrewing/tightening bleed screw | Incorrect tool size, cross-threading, corrosion. | Use the correct Torx wrench. Ensure the screw is aligned properly before tightening. If corroded, apply penetrating oil and use caution. Do not force. |
