Does Brake Fluid Need to Be Changed?
1 Answers
Brake fluid needs to be changed. The method for changing brake fluid is as follows: 1. Extract all the old brake fluid and fill it with new brake fluid; 2. Use a lift to raise the car, locate the brake caliper's bleed screw, and remove the dust cap from the bleed port; 3. Use a wrench to loosen the bleed screw, attach a rubber tube to it, and connect the other end to a drain bottle; 4. Press the brake pedal to expel the remaining old brake fluid. When the fluid in the tube becomes lighter in color, it indicates the fluid change is complete. Brake fluid, also known as hydraulic brake fluid, primarily functions to transmit pressure to the brake calipers. Its main roles include energy transmission, rust and corrosion prevention, heat dissipation, and lubrication. Brake fluid is divided into three types: alcohol-based, mineral oil-based, and synthetic.
