Why should you avoid using the parking brake after driving through deep snow or slush and then parking in freezing temperatures, on some vehicles?
- A.Parking brakes are banned in winter
- B.Frozen brakes release automatically at startup
- C.Moisture on brake components can freeze and lock the brakes; use wheel chocks and follow the vehicle guidance for the conditions
- D.Chocks are never an alternative
Correct answer
C. Moisture on brake components can freeze and lock the brakes; use wheel chocks and follow the vehicle guidance for the conditions
Why
Wet brake shoes and drums can freeze together overnight, leaving the vehicle unable to move or damaging linings when forced. Where the manufacturer and conditions call for it, chocking the wheels instead protects the brake hardware; on grades and per policy, follow the safest specified procedure for your vehicle.
