Brake drum brake system skillfully maintenance

    First, safety inspection should be strengthened before and after vehicle inspection, especially for braking, steering, transmission and wheel parts.
    Two, the pipeline inspection on the downhill before, especially some long and steep slope road, we must stop the car, look look at the road situation, and then carefully check the brake system, see the pressure is intact, pressure is sufficient,the brake pipe leaks (air brake), oil (hydraulic brake). The connecting parts have no signs of loosening. The situation should be solved in time and never have any fluke mentality. After all the above determination is unmistakable, go downhill again.
    Three, correct braking, use engine drag force and foot brake to control speed, prohibit stepping on clutch pedal or neutral skid, and avoid emergency braking.  In order to save oil, some drivers slide down the slope and even go out and slip, which is very dangerous. On the downhill, the center of gravity moves forward, and the inertia force becomes the driving force of the downhill, which accelerates the speed of the car. The more steep the slope, the heavier the vehicle, the faster the speed. The driver has to use the brake to reduce the speed, so as to ensure the safety of driving. In addition. The frequent use of foot brake, the air pressure loss in the tank is larger, the air compressor supply is insufficient, and the brake may eventually lead to inflexibility. If the drag force generated by the separation of the engine and the transmission is not reduced, the car will not run faster if the engine is not separated from the transmission. If the gear is lower, the drag force will be better, avoiding frequent braking and ensuring safety.
    Four, scientific driving can be driven in segments when the downhill slope is long and the bend is especially large and urgent. After a long run, find a place where the slope is slow and the front and back field is better. Stop on the one hand, make the storage tank full of gas, and on the other hand let the brake drum and hoof cool down before driving.
    Five, cooling brake drum of the car with the brake drum temperature, braking efficiency will be significantly decreased, so the car in the downhill before the water reservoir, water reservoir, open the switch, to make it to the outer surface of brake drum cooling, can effectively improve the braking efficiency.
    Six. Most cars with high quality brake fluid hydraulic brake use alcohol type brake fluid, and the alcohol content of the brake fluid is very volatile. Frequent brake, easy to increase the temperature of the brake pipe to produce gas resistance, so that the brake failure. If some high quality brake fluid with high boiling point and not easy to be deteriorated, the driving safety factor can be greatly improved.
    In conclusion, no matter how poor the driving condition is in plateau or hilly area, as long as you reasonably control the speed and brake, and be careful at all times, your safety can be guaranteed.
