Solution
1. Preparation
  • Gather tools including a socket set, brake fluid, and a brake bleeder kit.
  • Ensure the vehicle is parked on a level surface and the parking brake is engaged.
  • Wear safety gloves and goggles for protection.
2. Inspect the Brake Fluid System
  • Remove the master cylinder reservoir cap and inspect brake fluid level.
  • If low, fill with the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
  • Check for leaks in the brake lines, calipers, and hoses. Replace any damaged components.
3. Bleed the Brake System
  • Start with the wheel furthest from the master cylinder (usually the rear passenger side).
  • Attach the brake bleeder kit to the bleeder valve on the caliper.
  • Have an assistant press the brake pedal and hold it down.
  • Open the bleeder valve to allow air and old fluid to escape, then close it before the pedal is released.
  • Repeat this process until clear fluid comes out with no bubbles, then move to the next wheel in the following order: rear driver, front passenger, front driver.
4. Inspect and Replace Components if Necessary
  • Inspect the brake pads and rotors; replace if worn below specifications (minimum thickness for pads typically around 3mm).
  • Check the brake booster for proper function. If it is faulty, replace it.
  • If the master cylinder is leaking or damaged, replace it as well. Ensure to bench bleed the new master cylinder before installation.
5. Final Assembly
  • Reattach the master cylinder reservoir cap securely.
  • Recheck all brake line connections for tightness and leaks.
  • Lower the vehicle and perform a brake pedal test to ensure proper feel before the test drive.
