It is also important to do a good job in the daily maintenance of the brake drum. Let's introduce this to you.
1、 Strengthen the inspection before and on the way, especially the technical conditions of braking, steering, transmission and wheel parts must be intact to ensure reliable operation.
2、 Before the pipeline inspection is going downhill, especially on some long and steep slopes, you must stop the vehicle, observe the situation of the road, and then carefully check the working brake system to see whether the air pressure is intact, whether the air pressure is sufficient, whether the brake pipes are leaking (air brake), oil leakage (hydraulic brake), and whether the connecting parts are falling off.
3、 Reasonable braking uses the traction effect of the engine and the foot brake to control the speed. It is not allowed to step down the clutch pedal or slide in neutral, and avoid emergency braking. In order to save fuel, some drivers blindly slide in neutral when going downhill, or even turn off the engine, which is very dangerous. When going downhill, the center of gravity of the vehicle moves forward, and the inertia force becomes the driving force of the downhill, so that the driving speed of the vehicle will inevitably increase. The steeper and longer the slope is, the heavier the vehicle is, the faster the speed will be. The driver needs to brake to reduce the speed to ensure driving safety.
In addition. Frequent use of foot brake will cause large loss of air pressure in the air reservoir and insufficient air supply of the air compressor, which is likely to lead to insensitive braking. If the traction resistance caused by the engine not separating from the transmission device is used to reduce the speed when going downhill, the vehicle will not overspeed. The lower the gear, the better the traction effect, avoiding frequent braking and ensuring safety.
4、 Scientific driving When the downhill slope is relatively long and there are especially many sharp curves, you can drive in sections. After running for a distance, stop at a place with a gentle slope and good front and rear view. On the one hand, let the air reservoir be full of air, on the other hand, let the brake drum and shoe cool down, and then drive again.
5、 Cooling the brake drum When the vehicle is running, the brake efficiency will decrease significantly with the increase of the brake drum temperature. Therefore, the vehicle is equipped with a water reservoir. Before going downhill, turn on the water reservoir switch to make it pour water on the outer surface of the brake drum to cool down, which can effectively improve the brake efficiency.
6、 Most vehicles that use good brake fluid for hydraulic braking use alcohol-based brake fluid, which contains volatile alcohol. Frequent braking is easy to increase the temperature of the brake pipeline and cause air resistance, which will lead to brake failure. If some good brake fluid with high boiling point and not easy to deteriorate is selected, the driving safety factor can be greatly improved.
