What requirements does a rough terrain forklift have for brake fluid functionality?

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 blockages in pipelines, pumps, and other related components. When braking under such conditions, the brake pedal will feel very stiff and nearly impossible to press, rendering the forklift unable 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 linings remain in a braking state for too long, the temperature of the braking system will rise rapidly. If the brake fluid has a low boiling point and is prone to vaporization, the internal pipelines of certain braking systems will be filled with brake fluid vapor, creating resistance and leading to brake failure. Therefore, brake fluid with a higher boiling point and lower volatility should be selected, which will significantly reduce the probability of vapor lock in the forklift. 3. Appropriate viscosity: If the viscosity is too high, low-temperature fluidity will noticeably deteriorate, causing a significant decline in the forklift's braking performance. 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 over a long period, metal pipelines and components will be corroded. Therefore, an appropriate amount of rust inhibitor should be added to the brake fluid. 5. Chemical stability is also important: Since the brake fluid of off-road forklifts is used at high temperatures for extended periods, brake fluid with good chemical stability should be selected to prevent the oil from thickening due to thermal decomposition and polymerization, and to avoid the formation of sludge deposits. 6. Minimal impact on rubber: There are many rubber sealing components in the braking system of an off-road forklift. To prevent damage to the mechanical strength and elasticity of rubber sealing parts such as brake cups, the brake fluid should have as little swelling effect on rubber as possible. Additionally, care should be taken not to immerse rubber parts like cups in brake fluid for too long, as this will seriously affect the strength, volume, and quality of these related components.
