To perform a caliper brake adjustment on a bicycle, follow these steps:
- Loosen the brake cable pinch bolt to release tension on the cable.
- Use the barrel adjuster on the brake lever to adjust the cable tension.
- Align the brake pads so they are parallel to the rim and centered.
- Tighten the pinch bolt to secure the cable in place.
- Test the brakes to ensure they are working properly.
