How often should the brake fluid be replaced for Cadillac CT5?

[SanHarper]

Cadillac CT5 brake fluid replacement cycle is 30,000 kilometers. Brake fluid is the liquid used in the hydraulic braking system, which must not undergo chemical reactions, be unaffected by high temperatures, and should not cause corrosion, softening, or expansion to metals and rubber. Methods to determine if brake fluid needs replacement: 1. Visual Inspection: Open the brake fluid reservoir cap. If the brake fluid has become cloudy or black, do not hesitate and replace it immediately to avoid major issues. 2. Hard Braking Method: Drive the car normally to a speed above 40KM/H, then apply hard braking. If the braking distance is significantly longer, it can be concluded that there is a problem with the brake fluid, and it should be checked for replacement. 3. Soft or Unstable Braking During Normal Driving: If the brake pedal feels soft when pressed, it is time to consider replacing the brake fluid. If the brake fluid deteriorates, it will make the brake pedal feel spongy even when fully depressed. Frequent braking generates high temperatures, turning absorbed water in the brake fluid into steam and creating bubbles, leading to unstable braking force.
