Solution
1. Preparation
  • Gather tools and parts needed for repair.
  • Ensure the vehicle is parked on a level surface and engage the parking brake.
  • Disconnect the battery to ensure safety while working on the electrical components.
2. Inspect and Replace Brake Fluid
  • Sub-steps:
    • Remove the brake fluid reservoir cap and check fluid level.
    • If low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
    • If fluid is contaminated, proceed to flush the brake system.
3. Identify and Repair Leaks
  • Sub-steps:
    • Conduct a thorough visual inspection of brake lines, hoses, and fittings.
    • Repair or replace any damaged brake lines or hoses.
    • If leaks are found at the master cylinder or calipers, replace those components as necessary.
4. Inspect and Replace Brake Pads and Rotors
  • Sub-steps:
    • Remove the wheel to access the brake assembly.
    • Inspect brake pads for wear; replace if thickness is less than 3mm.
    • Inspect rotors for scoring or warping; resurface or replace if necessary.
    • Reassemble the brake components and secure the wheel.
5. Test and Replace Brake Booster (if necessary)
  • Sub-steps:
    • To test the brake booster, press the brake pedal several times and hold it down, then start the engine; the pedal should drop slightly.
    • If it does not, replace the brake booster.
    • Disconnect the brake lines and remove the booster; install the new booster by reversing the removal steps.
6. Bleed the Brake System
  • Sub-steps:
    • Begin bleeding 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 while you open and close the bleeder screw.
    • Repeat for each wheel in the order: rear passenger, rear driver, front passenger, front driver.
    • Ensure that the brake fluid reservoir is kept full during the process.
