Setup u Installazzjoni
Proper installation is crucial for safe and effective braking. If you are unsure about any step, consult a professional bicycle mechanic.
- Preparazzjoni: Ensure your bicycle frame and fork have appropriate mounting holes for nutted caliper brakes. Clean the mounting area thoroughly.
- Mounting the Calipers:
- Insert the long mounting bolt of the front caliper through the hole in the fork crown from the front. Secure it with the provided nut from the rear.
- Insert the shorter mounting bolt of the rear caliper through the hole in the seat stay bridge from the front. Secure it with the provided nut from the rear.
- Ensure the caliper is centered over the wheel rim.

- Brake Pad Adjustment:
- Loosen the brake pad fixing bolt.
- Position the brake pads so they are centered on the braking surface of the rim and parallel to the rim when the brake is applied.
- Ensure the pads do not touch the tire or fall below the rim's braking surface.
- Tighten the brake pad fixing bolt securely.
- Installazzjoni tal-kejbil:
- Route the brake cable from your brake lever through the cable housing and into the caliper's cable anchor bolt.
- Pull the cable taut, ensuring there is minimal slack, and tighten the cable anchor bolt.
- Trim any excess cable, leaving enough length to attach a cable end cap.
- Aġġustament Finali:
- Squeeze the brake lever several times to seat the cable and housing.
- Adjust the barrel adjuster on the brake lever or caliper to achieve the desired lever feel and pad clearance (typically 1-2mm from the rim).
- Ensure both brake pads contact the rim simultaneously and evenly.
Istruzzjonijiet Operattivi
The Tektro 900A brake set operates by pulling the brake levers, which in turn pulls the brake cable, causing the caliper arms to close and the brake pads to press against the bicycle rim, slowing or stopping the wheel.
- Teknika tal-Ibbrejkjar: Apply both front and rear brakes simultaneously for optimal stopping power and control. The front brake provides most of the stopping power, while the rear brake helps with stability and modulation.
- Modulazzjoni: Practice applying varying pressure to the brake levers to control your speed smoothly. Avoid sudden, hard braking, especially with the front brake, as this can lead to loss of control.
- Kundizzjonijiet imxarrab: In wet conditions, braking performance will be reduced. Apply brakes earlier and with more gentle pressure to clear water from the rim and pads before full braking.
Manutenzjoni
Regular maintenance will ensure the longevity and safe operation of your brake set.
- Tindif: Keep brake calipers, pads, and rims clean and free of dirt, grease, and debris. Use a clean cloth and mild detergent if necessary.
- Ilbies tal-Kuxxinetti tal-Brejk: Inspect brake pads regularly for wear. Replace pads when the wear indicators are no longer visible or when the pads become thin. Worn pads can damage rims and reduce braking effectiveness.
- Kejbil u Djar: Check brake cables and housing for fraying, kinks, or corrosion. Replace them if any damage is observed to maintain smooth brake operation.
- Pivot Points: Periodically apply a small amount of light lubricant to the caliper pivot points to ensure smooth movement. Avoid getting lubricant on brake pads or rims.
- Torque tal-Bolt: Periodically check all mounting bolts and cable anchor bolts for proper tightness. Refer to a bicycle repair manual for recommended torque specifications if available.
