2. Installation Instructions
Proper installation is crucial for safe and effective braking. If you are unsure about any step, consult a professional bicycle mechanic.
Tools Required:
- Hex key set (typically 5mm or 6mm)
- Cable cutters
- Brake cable and housing
- Electrical tape or bar tape
Installation Steps:
- Prepare Handlebars: Ensure your handlebars are clean and free of old tape or adhesive. Determine the desired position for your brake levers.
- Mount Levers: Slide the brake lever clamp onto the handlebar. Use a hex key to tighten the clamp bolt securely, but do not overtighten. Position the levers so they are comfortable to reach from both the drops and the hoods.
- Install Brake Cables:
- Pull back the rubber hood to expose the cable entry point.
- Insert the brake cable head into the lever mechanism.
- Route the cable through the lever body and out the designated exit point for internal routing.
- Route Housing: Cut brake housing to the appropriate length, ensuring smooth curves without kinks. Route the housing along the handlebars and frame, securing it with clips or tape as needed.
- Connect to Brakes: Attach the brake cable to your caliper or cantilever brake mechanism. Adjust cable tension to ensure proper brake pad clearance and lever feel.
- Test and Adjust: Squeeze the brake levers several times to seat the cables and housing. Re-check tension and adjust as necessary. Ensure both brakes engage firmly and release completely.
- Secure Cables and Tape Bars: Trim excess brake cable, leaving a few centimeters, and crimp an end cap onto the cable. Wrap your handlebars with bar tape, covering the brake housing for a clean finish.
Note: These levers are designed for use with caliper or cantilever brakes. They are not compatible with V-brakes (linear-pull brakes) or mountain disc brakes. For those systems, Tektro RL520 levers are recommended.
3. Operating Instructions
Braking:
To engage the brakes, gently squeeze the brake levers towards the handlebars. Apply even pressure to both levers for controlled stopping. For emergency stops, apply firm and progressive pressure. Always practice braking in a safe environment before riding in traffic.
Quick Release Mechanism:
The RL340 levers feature a quick release button or lever, typically located near the pivot point of the brake lever. Activating this mechanism temporarily increases the slack in the brake cable, allowing the brake calipers to open wider. This is useful for:
- Easier removal and installation of wheels, especially with wider tires.
- Clearing a wheel with a slightly buckled rim.
Ensure the quick release mechanism is disengaged (brake cable tension restored) before riding to ensure full braking power.
4. Maintenance
Regular maintenance ensures optimal performance and longevity of your brake levers.
- Cleaning: Wipe down the levers and rubber hoods with a damp cloth periodically to remove dirt and grime. Avoid harsh chemicals that could damage the rubber or finish.
- Cable Inspection: Regularly check brake cables for fraying, rust, or kinks. Replace damaged cables immediately. Ensure cables move freely within the housing.
- Housing Inspection: Inspect brake housing for cracks, damage, or compression. Damaged housing can impede cable movement and reduce braking efficiency.
- Lever Pivot Points: Apply a small amount of light lubricant to the lever pivot points annually or as needed to ensure smooth operation.
- Hood Condition: Check the rubber hoods for tears or excessive wear. Worn hoods can reduce grip and comfort. Replacement hoods are available.
- Tightness Check: Periodically check that the lever clamp bolts are securely tightened to the handlebars.
5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Brakes feel spongy or weak | Loose cable tension, worn brake pads, contaminated rim/rotor, stretched cable, damaged housing. | Adjust cable tension, inspect/replace brake pads, clean braking surfaces, replace cable/housing. |
| Brake lever does not return fully | Friction in cable/housing, sticky pivot point, damaged return spring. | Lubricate cable/housing, lubricate lever pivot, replace lever if spring is damaged. |
| Brakes rub on wheel/rotor | Too much cable tension, misaligned brake calipers, quick release engaged. | Reduce cable tension, adjust caliper position, ensure quick release is disengaged. |
| Lever feels stiff | Dirt or corrosion in cable/housing, dry pivot point. | Clean and lubricate cable/housing, lubricate lever pivot. Consider replacing cable/housing. |
