Have you ever heard a strange noise coming from the brake caliper while riding? If so, it means that your brake rotor and brake caliper are rubbing against each other when not braking. You need to adjust the positions of your brake rotor and brake caliper.
The image shows the correct and incorrect positions. The correct position is when the brake rotor is in the middle of the brake caliper without direct contact. The adjustment process is not difficult. You can watch an adjustment video on Asomtom's YouTube channel.
Tools: Multi-function hex key screwdriver
When the rotor rubs against one side of the brake pad, observe if the rubbing occurs above or below the caliper.
If the rubbing occurs above the brake pad, loosen the upper screw on the caliper and shift the caliper towards the rubbing side. Once you have positioned the caliper using your fingers, tighten the screw.
If the rubbing occurs below the brake pad, loosen the lower screw on the caliper and shift the caliper towards the rubbing side. Once you have positioned the caliper using your fingers, tighten the screw.
After the adjustment, rotate the wheel to ensure that the rotor is positioned in the middle of the brake pads, without rubbing and strange noises.
