What is the difference between brake fluid T3 and brake fluid T4?
1 Answers
The difference between brake fluid T3 and brake fluid T4 lies in their boiling points: the boiling point of brake fluid T3 is 205 degrees Celsius, while that of brake fluid T4 is 230 degrees Celsius. Brake fluid T4 is of a higher grade than brake fluid T3. The temperature in the braking system can get very high, and moisture can gradually accumulate in the brake fluid. High temperatures can cause this moisture to turn into gas, leading to poor braking performance, which is why it is necessary to replace the brake fluid regularly. Brake fluid is the liquid medium that transmits braking pressure in hydraulic braking systems, used in vehicles equipped with hydraulic braking systems. Within the braking system, it serves as a force transmission medium. Since liquids are incompressible, the pressure output from the master cylinder is directly transmitted to the wheel cylinders through the brake fluid.
