How to Solve Soft Brakes After Changing Brake Fluid?

[LeSilas]

Here are the solutions for soft brakes after changing brake fluid: 1. There is residual air in the brake system, caused by incomplete air bleeding from the pipelines during the brake fluid replacement process. When changing brake fluid, there are strict procedures and methods to follow. In this case, it is recommended to drive the vehicle to a repair facility to bleed the air. 2. The replaced brake fluid does not meet the required standards or has quality issues. Currently, the main types of brake fluid on the market are synthetic DOT3 and DOT4. The primary difference between DOT3 and DOT4 lies in their dry and wet boiling points. If the boiling point of the brake fluid is too low, it can easily vaporize in the system, causing airlock, which leads to delayed braking or even brake failure. In this situation, it is necessary to replace the brake fluid with a higher-quality one.
