5. Setup and Installation

The TEKTRO RL340 brake levers are designed for easy installation. Follow these general steps:

1. Prepare Handlebars: Ensure your drop handlebars are clean and free of obstructions where the levers will be mounted.
2. Position Levers: Slide the brake levers onto the handlebars. The levers are marked for left and right. Position them ergonomically for comfortable reach from both the hoods and the drops.
3. Secure Levers: Use a 5mm hex wrench to tighten the clamp bolts on the levers. Tighten securely, but do not overtighten, to avoid damaging the handlebars or the levers. Ensure the levers do not rotate on the bars when firm pressure is applied.
4. Install Brake Cables:
   • Open the lever body (usually by pulling the lever fully and locating a small access point or by peeling back the hood).
   • Insert the brake cable head into its designated slot within the lever.
   • Route the cable through the lever body and out the bottom or side, depending on your handlebar setup.
   • Feed the cable through the brake housing and connect it to your brake calipers.
5. Adjust Cable Tension: Adjust the cable tension at the brake caliper and/or using the barrel adjuster on the lever (if present) to achieve proper brake engagement and lever feel. Ensure there is no excessive slack and the brakes return fully when released.
6. Test Functionality: Before riding, thoroughly test both front and rear brakes to ensure they operate smoothly and provide adequate stopping power.

6. Operation

To operate the TEKTRO RL340 brake levers, simply squeeze the levers towards the handlebars. The amount of braking force is proportional to the pressure applied to the levers.

Quick Release Function:

The RL340 levers feature a quick-release button, typically located near the pivot point of the lever. Pressing this button will increase the slack in the brake cable, allowing the brake calipers to open wider. This is useful for:

• Easier removal and installation of wheels.
• Accommodating wider tires or fenders.

Remember to re-engage the quick-release mechanism after wheel installation and always check brake function before riding.

7. Maintenance

Regular maintenance ensures the longevity and safe operation of your brake levers:

• Cleaning: Wipe down the levers and hoods with a damp cloth to remove dirt and grime. Avoid harsh chemicals that could damage the finish or rubber.
• Cable Inspection: Periodically check brake cables and housing for fraying, kinks, or corrosion. Replace worn cables and housing promptly.
• Lubrication: Apply a small amount of bicycle-specific lubricant to the pivot points of the levers and where the cable runs through the housing to ensure smooth operation.
• Bolt Check: Ensure all mounting bolts remain tight. Re-tighten if necessary, adhering to recommended torque specifications.
• Hood Condition: Inspect the rubber hoods for tears or excessive wear. Replace if damaged to maintain grip and comfort.
