Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and engage the parking brake.
  • Wear safety glasses and gloves for protection.
2. Check Brake Fluid Level
  • Locate the master cylinder reservoir (typically on the driver's side near the firewall).
  • If the fluid level is low, top it off with the recommended brake fluid (DOT 3 or DOT 4).
  • If the fluid is contaminated or discolored, consider flushing the brake system.
3. Inspect for Leaks
  • Visually inspect brake lines and hoses for cracks or damage.
  • Check around the brake calipers and wheel cylinders for signs of fluid leakage.
  • If leaks are found, replace the damaged components before proceeding.
4. Examine Brake Pads and Rotors
  • Remove the wheel to access the brake components.
  • Inspect brake pads for thickness (minimum of 3mm) and rotors for scoring or warping.
  • Replace any worn brake pads or damaged rotors as necessary.
5. Test Brake Booster
  • With the vehicle off, pump the brake pedal several times to release vacuum.
  • Hold the pedal down and start the engine; the pedal should slightly drop as the booster engages.
  • If it does not, the brake booster may need to be replaced.
6. Bleed Brake System
  • If air was introduced into the brake lines, bleed the brakes to remove any trapped air.
  • Start from the wheel farthest from the master cylinder (usually the right rear) and work towards the closest (left front).
  • Use the two-person method or one-person bleeder kit to ensure proper fluid flow.
