- Regularly inspect brake pads for wear. Worn pads reduce braking effectiveness and can damage rims.
- Ensure brake cables are free from fraying, kinks, or corrosion. Replace damaged cables immediately.
- Proper brake adjustment is critical. Incorrectly adjusted brakes can be ineffective or cause wheel lock-up.
- If you are unsure about any installation or adjustment procedure, consult a qualified bicycle mechanic.
- Braking performance can be affected by weather conditions (e.g., rain, snow). Adjust your riding style accordingly.

4.1 Eines necessàries
- Hex Key Set (typically 5mm, 6mm)
- Talladores de cables
- Alicates
- Brake Cable Grease (optional)
4.2 Passos d'instal·lació
- Mount Calipers: Attach the front and rear brake calipers to the cantilever bosses on your bicycle's fork and frame using the provided mounting bolts. Ensure the arms pivot freely.
- Install Brake Pads: The 520.12 (55mm) standard pads are pre-installed. Ensure they are correctly oriented (often marked "L" for left and "R" for right, or with an arrow indicating rotation). Adjust the pad angle so they contact the rim squarely when the brake is applied.
- Attach Straddle Cable:
- Feed the main brake cable from your brake lever through the cable housing and then through the cable hanger.
- Attach the straddle cable to each brake arm using the small barrel adjusters.
- Connect the main brake cable to the straddle cable hanger.
- Adjust Pad Clearance: With the brake lever released, ensure there is approximately 2-3mm of clearance between each brake pad and the rim. Adjust the straddle cable length or the main cable tension to achieve this.
- Set Spring Tension: The TEKTRO Oryx 992AG features a Linear Spring Design and Dual Micro Tension Adjusters. Use the small screws on each brake arm to balance the spring tension, ensuring both pads move away from the rim equally when the brake is released.
- Cable segur: Once tension is set, tighten the cable fixing bolt on the caliper arm. Trim any excess brake cable, leaving approximately 2-3 cm, and crimp an end cap onto the cable to prevent fraying.
- Prova de frens: Squeeze the brake levers firmly several times to seat the cables. Check for proper function, ensuring smooth operation and effective stopping power. Re-adjust if necessary.
5. Instruccions de funcionament
The TEKTRO Oryx 992AG cantilever brakes are operated by your bicycle's brake levers.
- Frenatge: Squeeze the brake levers to engage the brakes. Apply pressure gradually for controlled deceleration. For emergency stops, apply firm and even pressure to both front and rear brakes.
- Fre davanter: Typically controlled by the left lever. Provides significant stopping power. Use with caution, especially on loose surfaces, to avoid locking the front wheel.
- Fre posterior: Typically controlled by the right lever. Provides stability and helps control speed. Less prone to causing skids than the front brake.
- Modulació: Practice modulating your braking force to achieve smooth and controlled stops. Avoid sudden, harsh braking unless absolutely necessary.
6. Manteniment
Regular maintenance will prolong the life of your brake set and ensure consistent performance.
- Brake Pad Inspection: Check brake pads regularly for wear indicators. Replace pads when they are worn down to the wear line or if they become hardened or contaminated.
- Inspecció del cable: Inspect brake cables and housing for fraying, kinks, or corrosion. Replace damaged cables and housing to maintain smooth brake operation.
- Neteja: Keep brake calipers and pads clean from dirt, mud, and road grime. Use a clean cloth and mild detergent if necessary. Avoid getting oil or grease on the brake pads or rim braking surface.
- Pivot Points: Periodically check the pivot points of the brake arms for smooth movement. Apply a small amount of light grease if they become stiff.
- Ajust de tensió: Re-adjust spring tension and cable tension as needed to maintain proper pad clearance and balanced braking.
7. Solució De Problemes
| Problema | Causa possible | Solució |
|---|---|---|
| Mal rendiment de frenada | Worn brake pads, contaminated pads/rims, loose cable, incorrect pad alignment. | Replace pads, clean pads/rims, tighten cable, adjust pad alignment. |
| Brakes squeal loudly | Contaminated pads/rims, incorrect pad toe-in, loose pads. | Clean pads/rims, adjust pad toe-in (slight angle), ensure pads are tight. |
| Brake lever feels spongy | Stretched cable, worn cable housing, loose cable fixing bolt. | Adjust cable tension, replace cable/housing, tighten fixing bolt. |
| One brake arm sticks or doesn't return | Uneven spring tension, dirty pivot, bent arm. | Adjust Dual Micro Tension Adjusters, clean/lubricate pivot, inspect for damage. |
