The housing should follow the existing path without sharp bends and must not restrict handlebar rotation. Also compare the barrel end and the inner wire diameter, which is approximately 1.5 mm.

Smooth operation and correct adjustment

• Replace the cable if the wire is frayed, corroded, the housing is damaged, or if it is binding. Check that the brake lever and caliper mechanism return freely.
• Route the wire along the existing path, seat the housing ends properly, and adjust the tension at the caliper. Cut the wire only after checking the length and finish with a cable end cap.
• Check braking performance, wheel clearance, and verify sufficient slack when turning the handlebars. Re-check the adjustment after initial use, as the cable may settle.
