Is It Normal for the Brake Pedal to Feel Harder After Changing Brake Fluid? Reasons for the brake pedal feeling harder after changing brake fluid: After changing the brake fluid, a break-in period is required. By gently applying the brakes more frequently while driving, the brake fluid will accelerate the break-in process, and the original pedal feel will quickly return. The hardness of the brake pedal after changing the fluid is also related to the quality of the brake fluid. It is recommended to purchase from reputable sources to avoid other issues. Reasons for the brake pedal feeling softer after changing brake fluid: This is most likely due to errors during the replacement process, causing air to enter the brake lines, which needs to be promptly bled out. If ignored, the moisture and impurities in the air can directly affect the water content of the brake fluid (lowering the dry and wet boiling points of the brake fluid). This not only increases the likelihood of vaporization in the system but also causes vapor lock, leading to delayed braking or even brake failure, which also affects the stability of the brake fluid.
