Inspect braking surfaces, pads, rotors or rims, controls, cables or hoses, and stopping behavior before adjusting anything.
Brakes are safety-critical
Treat reduced braking, leaks, damaged hoses or cables, contaminated pads or rotors, cracked parts, and uncertain setup as reasons to stop riding until the system is correctly inspected.
Work from observation rather than assumption: identify the exact component or symptom, consult the relevant specification when one exists, and verify the result before returning the bicycle to normal use.
Inspect the whole system
Look beyond the pads. Check the lever feel, cable or hose condition, caliper, fasteners, braking surface, wheel/rotor condition, and whether anything rubs or moves unexpectedly.
Work from observation rather than assumption: identify the exact component or symptom, consult the relevant specification when one exists, and verify the result before returning the bicycle to normal use.
Respect system-specific instructions
Rim, mechanical-disc, and hydraulic-disc systems have different procedures. Use the exact component manufacturer's service information for specifications, fluid type, pad compatibility, torque, and wear limits.
Work from observation rather than assumption: identify the exact component or symptom, consult the relevant specification when one exists, and verify the result before returning the bicycle to normal use.
Test before traffic
After any brake work, perform controlled stationary checks and low-speed tests in a safe area before returning to normal riding.
