Spin the wheel again and listen for rubbing noise between the rotor and pads:1.No rubbing noise = Calipers are centered correctly2.Rubbing on one side: Loosen the corresponding adjustment screw and fine-tune the caliper position until the noise disappearsBrake Performance Test1.Ride at low speed (below 5km/h), repeatedly applying the brakes to check for linear braking, abnormal noise, or pulling to one side.2.Test emergency stops: The wheel should lock smoothly without skidding or fishtailing when the lever is fully squeezed.3.Free-spinning test: Release the brake and ensure the wheel spins freely with no extra resistance.Common Issues & SolutionsProblem:Brake rubs on rotor Cause:Caliper not centered / Rotor warped Solution:Re-center the caliper; True the rotor or replace itProblem:Weak braking power Cause:Brake cable too loose / Worn brake pads Solution:Tighten the brake cable; Replace brake padsProblem:Brake lever does not return Cause:Broken spring clip / Stuck pistons Solution:Replace the spring clipReset pistons with pliers and clean the caliperMaintenance TipsNew brake pads require 50-100 brake applications to bed in. Reduced braking power during this period is normal.After riding in the rain, the pads may get wet and slippery. Lightly apply the brakes a few times to dry them out.Regularly check the brake cable for fraying and caliper bolts for looseness to avoid brake failure while riding.
