Compare routine inspection and maintenance considerations for rim brakes and disc brakes.
Treat braking as safety-critical
If braking is weak, inconsistent, leaking, damaged, or contaminated, stop and resolve the issue before normal riding.
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.
Identify your brake system
Rim brakes, mechanical discs, and hydraulic discs have different adjustment and service procedures. Component-specific documentation is the authority.

Keep friction surfaces clean
Lubricants and many cleaners can ruin braking performance. Protect pads, rotors, and rim braking surfaces from contamination.

Test methodically
After maintenance, verify fasteners and wheel retention, operate the brakes while stationary, then perform a controlled low-speed test away from traffic.
