Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is on a flat surface and secure it with wheel chocks.
  • Wear protective eyewear and gloves.
2. Inspect and Top Off Brake Fluid
  • Locate the master cylinder reservoir.
  • Remove the cap and check the fluid level; add DOT 3 or DOT 4 brake fluid as needed.
  • Replace the cap securely.
3. Check for Leaks
  • Visually inspect all brake lines, calipers, and the master cylinder for signs of fluid leakage.
  • If leaks are found, proceed to replace the damaged components.
4. Bleed the Brake System
  • Start at the wheel farthest from the master cylinder (usually the rear passenger side).
  • Use a brake bleeder kit or a helper to pump the brake pedal and open the bleeder valve to release air.
  • Repeat for each wheel until clear brake fluid is seen without bubbles, ensuring that the master cylinder does not run dry during the process.
5. Inspect Brake Components
  • Remove the wheel to access the brake assembly.
  • Inspect brake pads for thickness; replace if less than 3mm.
  • Check rotors for scoring or warping; resurface or replace if necessary.
6. Test Brake Booster (if needed)
  • With the engine running, press the brake pedal; it should feel firm.
  • If the pedal sinks, the brake booster may be faulty and should be replaced.
