Should I Always Use My Parking Brake?

When It Makes Sense

• Good fit: On steep inclines or declines, engaging the parking brake every time you park prevents the vehicle from rolling and reduces strain on the transmission.
• Good fit: In manual‑transmission cars, using the parking brake while the car is in gear adds an extra layer of security, especially on uneven surfaces or when the car will sit for an extended period.

When You Should Avoid It

• Warning sign: If you drive an automatic transmission vehicle on a flat, level surface and rely on the “Park” (P) gear, repeatedly pulling the parking brake can cause unnecessary wear on the brake shoes or pads.
• Warning sign: In very cold climates, engaging the parking brake and then immediately starting the engine can cause the brake mechanism to seize, making release difficult.

Pros and Cons

Pros

• Provides an extra safety barrier that protects against accidental rolling, especially on slopes.
• Reduces stress on the transmission’s parking pawl, extending its service life when used in conjunction with the park gear.

Cons

• Frequent use can accelerate wear of brake components, leading to earlier replacement costs.
• If not released properly, the parking brake can bind, causing difficulty when moving the vehicle and potentially damaging cables or actuators.

Decision Checklist

• Is the vehicle parked on an incline, decline, or uneven surface?
• What type of transmission does the vehicle have (automatic vs. manual) and how often is the vehicle left idle?
• Are environmental conditions (cold, moisture) likely to affect brake release?

Alternatives to Consider

Instead of always pulling the parking brake, you can rely on the transmission’s park position for flat surfaces, use wheel chocks for trailers or heavy loads, and engage the parking brake selectively on inclines. For electric or hybrid vehicles with electronic parking brakes, following the manufacturer’s recommendations—often a single pull for steep grades—can replace manual use.

Final Recommendation

In most everyday driving situations on level ground, using the transmission’s park gear is sufficient and less wear‑prone. However, on hills, with manual gearboxes, or when extra safety is desired, habitually engaging the parking brake is a prudent habit. Always consult your vehicle’s owner manual and, for high‑risk scenarios (e.g., heavy trucks on steep grades), seek advice from a qualified mechanic or driving instructor.
