What should you do before going down a long, steep hill in a lorry?
- Stay in a high gear and use only the footbrake all the way
- Choose a lower gear before the descent, and use the endurance brake
- Select neutral at the top and coast down to save fuel
- Speed up near the top so the descent takes less time
Ipakita ang sagot
Sagot: B. Choose a lower gear before the descent, and use the endurance brake
A lower gear and an endurance brake (retarder) help control speed so the service brakes do not overheat and fade.
Tanong 7 ng 25
What can happen if you use the footbrake continuously on a long downhill stretch?
- The fuel will start to freeze
- The tyres will over-inflate
- The brakes can overheat and fade
- The engine will stall
Ipakita ang sagot

Continuous braking makes brakes overheat and lose effectiveness. Use a lower gear and the retarder.
