Does Installing a Secondary Brake Affect a New Car?

Installing a secondary brake in a new car has negative effects, as it can deprive the driver of autonomy and compromise safety. Loss of Autonomy: Novice drivers lack anticipatory judgment. Upon hearing an emergency command, they might panic and mistake the accelerator for the brake. Even with the assistance of a secondary brake, prolonged use can lead to dependency. While this may resolve immediate crises, it fails to foster independent decision-making. The novice driver remains like a puppet, struggling to grow quickly. Safety Risks: A basic secondary brake functions similarly to a bicycle handbrake. If pressed too hard or too frequently, it may fail to return fully or at all. Driving under such conditions is akin to pressing both the brake and accelerator simultaneously—dragging the brakes while driving. Within a short time, a burning smell may emerge, and the brake pads could quickly wear out.

What Belts Does the Engine Have?

The engine contains several belts including the timing belt, balance shaft belt, alternator and water pump belt, air conditioning belt, and power steering pump belt. A broken timing belt can cause damage to the car and requires regular replacement. Impact of the Timing Belt: If the timing belt is damaged, it can lead to loss of power and abnormal engine noises. In severe cases, it may cause the engine to fail completely. When the timing belt breaks, the engine's pistons continue to move up and down due to inertia, while the valves and ignition system stop functioning properly. This can cause the pistons to collide with the valves, resulting in deformation of both components and engine failure. Minor collisions may lead to power loss or engine issues, while severe collisions can render the car inoperable. Replacement Interval: The timing belt works in conjunction with the crankshaft to maintain the correct transmission ratio for proper engine operation. As a wear-prone component, the timing belt is susceptible to aging and should be replaced approximately every 50,000 kilometers.

What lubricant is used for tire installation?

Tire grease is used. Grease can be divided into four categories. Bearing grease: A lubricating oil formulated with low-viscosity synthetic lubricating oil and various additives such as antioxidants and anti-corrosion agents. High-temperature grease: Contains a high concentration of PTFE (polytetrafluoroethylene) lubricating particles, with strong high-temperature resistance and pressure-bearing capacity, suitable for high-temperature and heavy-duty equipment. Lithium-based grease: Made from natural fatty acid lithium soap, thickened with medium-viscosity mineral lubricating oil or synthetic lubricating oil, or from synthetic fatty acid lithium soap, thickened with medium-viscosity mineral lubricating oil. Silicone grease: Abbreviated as silicone grease, it is made by thickening lubricating oil with silicone as the thickener.

Does Low Oil in a Spraying Machine Affect Pressure?

Low oil in a spraying machine does not affect pressure. Insufficient pressure indicates that the return valve is not functioning properly. You can take it to an after-sales service center and have the staff replace the return valve. Precautions: During use, regularly check the safety valve in operation for leaks, blockages, spring corrosion, and other abnormal phenomena. Also, observe whether the adjusting screw sleeve and the lock nut of the adjusting ring set screw are loose. If any issues are found, take appropriate maintenance measures promptly. Periodically remove the safety valve for thorough cleaning: After inspection, re-grinding, and recalibration, it can be reused. Safety valves installed outdoors should have appropriate protective measures to prevent rain, fog, dust, rust, and other contaminants from entering the safety valve and discharge pipeline. When the temperature falls below zero degrees Celsius, necessary anti-freezing measures should also be taken to ensure the reliability of the safety valve's operation.
