Why should you not use the parking brake as a substitute for regular braking?

• A. It can overheat the brakes or cause brake system damage, especially on long descents.
• B. It improves fuel efficiency.
• C. It is illegal.
• D. It has no effect on braking.

Answer: (A)

Parking brakes are meant to hold the vehicle in place or provide backup braking, not to handle normal stopping. They usually affect only the rear brakes and aren’t built to dissipate heat as effectively as the regular hydraulic brakes. Using the parking brake as your primary brake, especially on long descents, can cause the brake components to overheat, leading to brake fade, reduced stopping power, or damage to the brake system. Rely on the service brakes for regular stopping and use the parking brake only for parking or in an emergency if the primary system fails.
