Troubleshooting

Brakes feel spongy or lack stopping power.

Check and adjust the cable tension. Inspect brake pads for wear and replace if necessary. Bleed the brake lines if air is present (although these are mechanical, and this is less likely).

Brakes are rubbing or making noise.

Adjust the caliper alignment to ensure the brake pads are not rubbing against the rotor. Check that the rotor is straight and not warped. Check for contamination on the rotors.
