In rainy seasons, slippery roads and frequent puddles will greatly extend the braking distance of trucks and easily cause short circuits due to damp circuits, leading to rear-end collisions and vehicle breakdowns. For drivers of HOWO NX and other cargo trucks operating cross-border and mountain routes, protecting the braking system and vehicle circuits is the core of safe driving.
Road friction drops sharply on rainy days, making brake performance critical to safety. Before departure, drivers shall check for water seepage and air leakage on air storage tanks and brake pipelines, and inspect brake pad thickness; heavily worn pads need timely replacement. After wading, moisture trapped inside brake drums and pads weakens braking power. Drivers should drive at low speed and tap the brakes repeatedly to dry components via heat, instead of driving at high speed with full loads right after crossing water. Vehicles equipped with exhaust auxiliary brakes shall use them first on downhill roads to reduce frequent use of main brakes and avoid brake failure caused by overheating. Regular replacement of air dryers prevents moisture from corroding valve bodies and extends the service life of the entire brake system.
Water seeping into wiring connectors, fuse boxes and generators often triggers short circuits, lighting failures and hard starting, delaying delivery schedules. Before daily trips, check if wiring sheaths under the cab and chassis are cracked; wrap exposed wires tightly with waterproof tape and coat battery terminals with grease to resist rain corrosion. Avoid deep puddles to prevent water from submerging chassis wires and generators. If the truck wades through deep water, do not start the engine immediately. Open the cab to wipe and air-dry the fuse box and ECU plugs before ignition. Park on high, dry ground instead of low-lying puddled areas to stop circuit dampness.
Many fleet operators skip special rainy-season maintenance to cut costs, only to face expensive repairs and transport suspension after brake or circuit damage. Fleets may set up inspection records to service brake air circuits and full vehicle wiring after each trip and replace aging waterproof parts. Slow down and keep a safe distance in heavy rain; avoid sudden braking and sharp steering.
Safety guarantees stable freight profits. Never take chances while driving in rain. Proper moisture-proof treatment for brakes and waterproof protection for circuits, plus regular maintenance and standardized wading operations, can cut breakdown risks and traffic accidents, prolong the service life of chassis and electrical components, and ensure efficient and stable transportation.
