What are the requirements for brake fluid function in rough terrain forklifts?

1. Outstanding low-temperature performance: If the brake fluid of an off-road forklift has poor fluidity or even solidifies at low temperatures, it will cause blockage in pipelines, pumps, and other related components. When braking at this time, the brake pedal will feel extremely hard and almost impossible to press down, making it impossible for the forklift to brake. 2. High boiling point requirement: In each working cycle of an off-road forklift, forward and reverse movements are frequently repeated. If the brake friction plates remain in the braking state for too long, the temperature of the brake system will rise rapidly. If the brake fluid has a low boiling point and vaporizes easily, then for some brake systems, the internal pipelines of the system will be filled with brake fluid vapor, thereby creating resistance and causing brake failure. Therefore, brake fluid with a higher boiling point and lower vaporization tendency should be selected, so that the probability of vapor lock in the forklift will be greatly reduced. 3. Appropriate viscosity: If the viscosity is too high, low-temperature fluidity will deteriorate significantly, and the braking performance of the forklift will also drop sharply. If the viscosity is too low, reliable lubrication cannot be provided at high temperatures, and some leakage may occur. 4. Good corrosion resistance: If brake fluid with poor corrosion resistance is used for a long time, metal pipelines and components will be corroded. Therefore, it is required to add an appropriate amount of rust inhibitor to the brake fluid. 5. Chemical stability is also very important: Since the brake fluid of off-road forklifts is used at high temperatures for a long time, in order to avoid thermal decomposition and polymerization of the oil that increase viscosity, and also to prevent the formation of sludge deposits, brake fluid with good chemical stability should be selected. 6. Small impact on rubber: There are many rubber sealing components in the brake system of off-road forklifts. In order to avoid damage to the mechanical strength and elasticity of rubber sealing components such as brake cups, it is required that the effect of brake fluid on the swelling rate of rubber be as small as possible. In addition, note: do not let rubber components such as cups soak in brake fluid for too long, otherwise the strength, volume, and mass of the related components will be seriously affected.
