How to operate the 4.2-meter air brake?
4 Answers
First, gradually and lightly press the brake pedal to one-fourth to one-sixth of its travel and hold it steady. Once the braking effect is achieved, slowly and sequentially release the pedal. Gradually and sequentially press the brake pedal to one-third to one-half of its travel and hold. After the speed has significantly decreased, press further until the vehicle comes to a complete stop, then slowly release the pedal.
I've driven this 4.2-meter truck for years and am quite proficient with air brake operation. Before starting, always check the air pressure gauge - never move if it's below 6 bar. Start the engine and wait a few minutes for the pressure to build up. When driving, gently press the brake pedal without sudden force to avoid wheel lockup, especially being extra cautious on slippery roads. When parking, use the air parking brake to lock the wheels, and on slopes I always add wheel chocks as an extra precaution against rolling. Before shutting down, release excess air pressure to protect the air compressor. Remember to check air hose connections monthly for leaks - safe driving is paramount. From experience, gentle operation extends system life. I always perform pre-trip inspections to avoid breakdowns and delays on the road.
As a regular car owner, my operation of the air brake on a 4.2-meter truck is quite basic. First, before starting, check if the air pressure gauge is in the green zone; if it's too low, wait a bit for the engine to build up pressure. While driving, control the brake pedal with appropriate force, pressing gently for a smooth stop. When parking, pull the small handbrake lever to ensure it's locked, and release the air pressure by pushing the air valve before turning off the engine. When heavily loaded or in rainy weather, brake earlier to maintain distance. I also regularly monitor air pressure changes to prevent leaks and replace air hose gaskets every quarter to prevent aging. A tip: New drivers should practice more to become proficient and stress-free.
I prioritize safe driving operations and never take air brakes lightly. Before starting a 4.2-meter truck, I always check that the air pressure meets standards. While driving, I apply brakes evenly to avoid sudden stops and fishtailing. When parking, I always use the air parking brake to securely lock the wheels, especially on slopes where I add double protection. If I encounter abnormal air pressure, I immediately pull over to inspect the air lines. For maintenance, I clean air tank impurities every six months to ensure smooth operation. Safety comes first, and I make it a habit to pay attention to road conditions and details.
