Solution
1. Preparation
  • Ensure the vehicle is on a level surface and secure it with wheel chocks.
  • Gather necessary tools and parts before starting.
2. Inspect and Replace Brake Fluid
  1. Remove the brake fluid reservoir cap and check the fluid condition.
  2. If the fluid is contaminated, siphon out the old fluid using a turkey baster.
  3. Fill the reservoir with new brake fluid (DOT 4 specification).
  4. Replace the reservoir cap securely.
3. Check for and Repair Leaks
  1. Visually inspect the brake lines, calipers, and master cylinder for leaks.
  2. If leaks are found, replace the affected component (e.g., brake line, caliper).
    • Use a wrench to disconnect the leaking line or caliper.
    • Install the new part and tighten to manufacturer specifications.
    • Ensure all connections are secure and leak-free.
4. Bleed the Brake System
  1. Attach a brake bleeder kit to the brake bleeder valve on each caliper.
  2. Start with the caliper furthest from the master cylinder (usually the rear passenger side).
  3. Have an assistant press the brake pedal while you open the bleeder valve to release air and old fluid.
  4. Close the valve before the pedal is released. Repeat until fluid is clear of bubbles.
  5. Move to the next caliper and repeat the process until all calipers are bled.
5. Test Brake System
  1. Recheck the brake fluid level and top off as necessary.
  2. Start the vehicle and press the brake pedal firmly to ensure proper function.
  3. Perform a test drive in a safe area to confirm the brakes are responsive.
