How to do a good job in daily maintenance of brake drums is also quite important. Below, we will introduce this to you.
1、 Strengthen the inspection work before and during the journey, especially the technical condition of the braking, steering, transmission, and wheel parts must be intact to ensure reliable operation.
2、 Before the pipeline inspection work is about to go downhill, especially on some long and steep slopes, it is necessary to stop the vehicle and observe the situation of the road. Then, carefully inspect the working brake system to see if the air pressure is intact, whether the air pressure is sufficient, whether there is air leakage (pneumatic braking) or oil leakage (hydraulic braking) in each brake pipeline, and whether there is any detachment phenomenon in each connection part.
3、 Reasonable braking utilizes the traction effect of the engine and the foot brake to control the vehicle speed. Do not press the clutch pedal or coast in neutral, and avoid emergency braking. Some drivers, in order to save fuel, blindly slide in neutral or even turn off the engine when going downhill, which is very dangerous. When going downhill, the center of gravity of the vehicle moves forward, and the inertial force becomes the driving force for the downhill, which inevitably accelerates the vehicle's speed. The steeper and longer the slope, the heavier the vehicle, and the faster the speed. The driver needs to use brakes to reduce the speed to ensure driving safety.
Additionally. Frequent use of foot brakes can result in significant loss of air pressure in the air storage cylinder, insufficient air supply from the air compressor, and may lead to less responsive braking. If the traction force generated by the engine not separating from the transmission device is used to reduce the speed when going downhill, the vehicle will not exceed the speed limit. The lower the gear, the better the traction effect, avoiding frequent braking and ensuring safety.
4、 Scientific driving allows for segmented driving when encountering long downhill slopes and particularly sharp curves. After running for a distance, stop at a slightly gentle slope with good front and rear visibility. On the one hand, let the air reservoir be fully inflated, and on the other hand, let the brake drum and shoes cool down before driving.
5、 During the operation of a vehicle with a cooling brake drum, as the temperature of the brake drum increases, the braking efficiency will significantly decrease. Therefore, the vehicle should be equipped with a water reservoir. Before going downhill, turn on the water reservoir switch to spray water onto the outer surface of the brake drum to cool down, which can effectively improve braking efficiency.
6、 Most vehicles that use good brake fluid for hydraulic braking use alcohol based brake fluid, which contains volatile alcohol. Frequent braking can easily cause an increase in the temperature of the braking pipeline, resulting in air resistance and brake failure. If some good brake fluid with high boiling point and not easy to deteriorate is selected, it can greatly improve the driving safety factor.
