Factors affecting braking effect 3.Mountain Environment Because of the high mountain and long slope in mountain environment, the brake has high frequency and long time, and often works continuously under high-intensity braking conditions, these factors will make the braking efficiency worse. Therefore, when the vehicle goes downhill, do not slide in neutral and avoid frequent braking. Try to use the low gear to control the vehicle speed through the auxiliary brake action of the engine, which can reduce the working strength of the wheel brake and reduce the brake temperature.
When using engine assisted braking, the lower the transmission gear, the higher the engine speed, the greater the drag force and the more obvious the braking effect. 4.Plateau environment Due to the thin air and low air pressure in plateau area, the brake vacuum power will become smaller, so it is necessary to apply more brake pedal force when braking in plateau area. When it is necessary to brake, do not step on the brake pedal with the method of snub, but keep the foot on the brake pedal to ensure the braking efficiency by controlling the brake pedal force.
5.Ice and snow weather Due to the low friction coefficient of ice and snow road, the braking distance will be greatly extended when braking, and the braking distance will increase with the increase of vehicle speed, so when driving on ice and snow road, special attention should be paid to control the speed and keep a large safety distance from the front and side vehicles. 1.Wear The wear of the brake pads depends to a great extent on the service conditions and driving mode, especially for those vehicles that often drive in urban traffic and short distance or in sports mode. Therefore, it is necessary to check the thickness of the brake pad within the specified time interval of maintenance.
2.Wet or salty roads Wet road: when driving in ponding or heavy rain, or after washing the car, the brake disc and brake pad will be wet or frozen in winter, the braking efficiency will be reduced. Lightly press the brake pedal to dry the brake and restore the performance. Road for sprinkling salt: when driving on the road for sprinkling salt, if the brake is not used for a long time, there will be salt layer on the brake disc and brake pad, and the braking efficiency will be reduced. Lightly press the brake pedal to remove the salt layer on the brake disc and brake pad. is forbidden to slide in the air on snow and ice roads.
6.Brake disc surface rust If the vehicle is parked for a long time, the brake disc may be rusted and the brake pads may be fouled. It is recommended that you drive at a low speed and brake several times before the official driving to clean the brake disc. Danger 149
