Solution
1. Preparation
  • Gather tools: brake fluid, socket set, brake bleeder kit, wrench set, and a container for old fluid.
  • Ensure the vehicle is parked on a level surface with the engine off and the parking brake engaged.
2. Inspect and Address Brake Fluid Level
  • Open the hood and locate the brake fluid reservoir.
  • Check the fluid level; if low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
  • If the fluid is contaminated, proceed to flush the system.
3. Inspect for Leaks
  • Visually inspect all brake lines, calipers, and the master cylinder for signs of leakage.
  • If any leaks are found, replace the damaged component (e.g., brake line, caliper, or master cylinder) as necessary.
4. Bleed the Brakes
  • Attach the brake bleeder kit to the brake bleeder valve on one of the brake calipers.
  • Have an assistant pump the brake pedal several times and hold it down.
  • Open the bleeder valve to release air and old fluid, then close the valve before the pedal is released.
  • Repeat the process for each wheel, ensuring no air remains in the system.
  • Check the brake fluid level frequently and top it off as needed.
5. Inspect and Replace Brake Components (if necessary)
  • Remove the wheel to access the brake pads and rotors.
  • Inspect the brake pads for thickness; replace if worn down to the indicator.
  • Check the rotors for warping or scoring; replace if necessary.
  • Reassemble the wheel and lower the vehicle.
