Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Ensure the vehicle is parked on a level surface with the parking brake engaged.
  • Wear safety glasses and gloves.
2. Check and Refill Brake Fluid
  • Sub-steps:
    1. Open the hood and locate the brake master cylinder.
    2. Remove the cap and visually inspect the brake fluid level.
    3. If low, add the appropriate type of brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
    4. Replace the cap securely.
3. Inspect for Leaks
  • Sub-steps:
    1. Visually inspect all brake lines and hoses for signs of leakage or damage.
    2. Check around the brake calipers and wheel cylinders for fluid seepage.
    3. Clean any areas with brake cleaner and dry them to check for fresh leaks over time.
4. Bleed the Brake System
  • Sub-steps:
    1. Start at the wheel farthest from the master cylinder (usually the right rear).
    2. Attach a brake bleeder kit to the bleeder valve on the brake caliper.
    3. Open the valve and have an assistant press the brake pedal down, then close the valve before they release the pedal.
    4. Repeat until no air bubbles are present in the fluid, then move to the next wheel in order (right rear, left rear, right front, left front).
    5. Ensure the brake fluid reservoir does not run dry during the process.
5. Replace Worn Components
  • Sub-steps:
    1. If brake pads or rotors are worn, remove the wheel and tire.
    2. Use a socket set to remove the caliper bracket bolts.
    3. Replace brake pads and rotors as necessary, following manufacturer specifications for torque values.
    4. Reinstall the caliper and wheel, ensuring all components are secured properly.
