Brake pads generally need to be replaced every 25,000 to 65,000 miles, while brake discs (rotors) last about 30,000 to 70,000 miles. The exact timing depends heavily on vehicle type, driving habits, terrain, and how often brakes are used. Regular inspection is recommended at least once a year or every 10,000 to 12,000 miles to assess wear and safety. If brake pedal responsiveness decreases, stopping distance increases, burning smells occur during braking, or unusual sounds are heard, brakes should be checked immediately for replacement needs.

Key factors influencing brake wear include:

• Driving style, such as frequent stopping or riding the brakes.
• Terrain (city driving with frequent stops vs. highway driving).
• Vehicle load and usage conditions.

It is advisable to have brakes checked by a professional regularly and to replace pads and rotors together to prevent damage from warped rotors.
