Summer agricultural vehicle maintenance precautions
1. Do not use alcohol type and mineral oil type brake fluid. To use high-quality synthetic brake fluid, this brake fluid has a balanced reflux boiling point of at least 190°C. Under high temperature conditions, it is not easy to produce "air resistance", and at the same time it does not cause corrosion and swelling to the rubber parts of the brake system. 2. Always check and adjust the technical state of the brake system. Including: the timely addition and replacement of brake fluid; correct adjustment of the brake gap, to prevent the brake linings and the brake drum clearance is too small or the normal direct contact between the two vehicles, resulting in brake operating temperature is too high; if you find the brake soft Tubes, cylinders, bowls, and brake linings are damaged and must be replaced promptly. 3. If you feel that the brake pedal is soft during driving, you should stop immediately, rest in a cool place, and let the brake drum cool down. 4. If the agricultural transporter is operated under harsh conditions for a long time, consider installing a brake drum dripping cooling device to improve the cooling conditions of the brake drum. However, do not pour cold water into the tire immediately after stopping to prevent the brake drum from cracking. 5, to strengthen the maintenance of the brakes, for the accumulation of dust in the wheel brakes, oil, rust and the fine friction plate, to be cleaned and rust; for the oil on the brake friction plate, you must find out the reason, and to be excluded, Then replace the grease-contaminated friction plate. 6. When repairing the brake drum, the “sulfuric acid corrosion method†can be used to remove the hardened layer on the surface of the brake drum. The method is: clean the brake drum working surface with a cotton yarn dipped in the electrolyte (sulfuric acid solution) of the battery, and then wipe the surface of the brake drum clean with a clean cotton yarn, and then rub the brake rubbing sand with a sandcloth, and finally Follow the repair process for assembly and commissioning. The above points are very important to prevent the brake failure of agricultural vehicles in high temperature seasons and ensure the safety of vehicles. They should be strictly followed during use.
