Troubleshooting Common Issues

Issue #1: Leaks at the Adapter Connection

Problem: Mineral oil leaks from where the syringe or funnel adapter connects to the brake lever or caliper, making a mess and preventing a proper bleed.

Solution: Ensure you’re using the correct adapter from the “various adapters” included. Hand-tighten firmly, and use the provided hook and loop fasteners to secure the hose and relieve strain on the connection. The plastic adapters can crack if overtightened.

Prevention: Test the fit of the adapter before adding fluid to the system.

Issue #2: Air Bubbles Persist in the System

Problem: After bleeding, the brake lever still feels spongy, indicating trapped air bubbles.

Solution: Use the transparent funnel to your advantage. Tap the brake line gently with a tool while monitoring the funnel; bubbles will rise visibly. Ensure you’re using enough of the 120ml fluid volume to fully flush the system. The two-syringe setup allows for a push-pull method to dislodge stubborn bubbles.

Tech Note: The kit’s mineral oil is formulated to prevent corrosion, but old, contaminated fluid can hold more air.

Issue #3: Fluid Level is Hard to See in the Funnel

Problem: Despite the transparent funnel, it’s difficult to monitor the exact fluid level during the bleed.

Solution:

• Ensure you have adequate lighting on your work area.
• Keep the bike and funnel as level as possible during the process.
• Use the funnel’s design to “easily monitor where the oil is” by watching for the distinct fluid meniscus against the clear plastic.

Issue #4: Brakes Feel Worse After Bleeding

Problem: Lever feel is mushy or there’s no pressure after using the kit.

Solution: This usually indicates a major air introduction or incorrect adapter use. Start over, ensuring all connections are tight before beginning. Follow the “clear and straightforward instructions” precisely, particularly the sequence for opening/closing bleed ports. Verify your brakes use mineral oil, not DOT fluid.

Safety Feature: The included gloves protect your skin from fluid, allowing you to work carefully without rushing.

Issue #5: Syringe Plunger is Sticky or Hard to Move

Problem: The plastic syringe plunger doesn’t move smoothly, making fluid transfer difficult.

Solution: Apply a tiny drop of mineral oil to the syringe barrel to lubricate the plunger seal. Do not use other lubricants, as they can contaminate the brake system. The plastic construction is lightweight but may require this minor maintenance for optimal performance.

Frequently Asked Questions

How many brake bleeds can I do with the 120ml of fluid?

The kit includes 2 x 60ml bottles of high-performance mineral oil brake fluid, totaling 120ml. A typical full bleed (front and rear brake) on a mountain bike consumes approximately 30-50ml of fluid. Therefore, you can realistically perform 2-4 complete bleeds, which validates the product’s claim that it “can be changed several times.” This makes it excellent value for maintaining multiple bikes or performing seasonal services.

Is this kit compatible with SRAM or Magura DOT fluid brakes?

No, this Cyctravel kit is specifically designed for mineral oil brake systems only. The product description clearly states compatibility with Shimano, TEKTRO, and TRP hydraulic disc brakes, which all use mineral oil. Using this mineral oil in SRAM or Magura brakes that require DOT fluid will cause seal damage and brake failure. Always verify your brake’s fluid type before purchase.

What specific adapters are included in the “various adapters”?

The product listing states “various adapters” are included but does not list exact part numbers. Based on the stated compatibility with Shimano, Tektro, and TRP brakes, the kit should contain the common plastic threaded adapters that fit the bleed ports on brake levers and calipers from these brands. For precise fitment, especially on newer models, cross-reference the adapter shape with your brake’s service manual.

Does the mineral oil prevent corrosion as claimed?

Yes, according to the product information, the fluid has a “Specific Use For Product” listed as “Prevent Corrosion.” High-quality mineral oil, like that included in this kit, is non-hygroscopic (doesn’t absorb water) and contains additives that protect the internal aluminum and steel components of your brake system from oxidation and corrosion over time.

Is the funnel compatible with all brake levers?

The transparent funnel is designed to work with the included adapters that thread into the brake lever’s reservoir port. It is not a universal fit for every lever directly. You must use the correct adapter from the kit to create a sealed connection between the funnel and your specific Shimano, Tektro, or TRP brake lever. The hook and loop fasteners help secure this connection.

What does the 2-year warranty cover?

The product comes with a 2-year warranty from the manufacturer, Jincheng Tianqi Technology Co., Ltd. This warranty typically covers defects in materials and workmanship for the components in the kit, such as the syringes, funnel, and adapters. Consumable items like the mineral oil fluid and gloves are generally not covered. For warranty claims, contact the “cyctravel Store” seller through Amazon.
