Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is on a level surface and securely supported with jack stands.
  • Disconnect the negative terminal of the battery.
2. Check and Replace Brake Fluid
  • Tools Required: Brake fluid, funnel, clean cloth.
  • Inspect the brake fluid level; if low, top it off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4 as specified).
  • If the fluid is dark or contaminated, proceed to flush the brake fluid system.
  • Use a brake bleeder kit to remove old fluid from the brake lines:
    1. Connect the bleeder kit to the brake bleeder valve on the calipers.
    2. Open the valve and pump the brake pedal until clean fluid flows out.
    3. Close the valve and refill the master cylinder as necessary.
3. Inspect and Replace Brake Components
  • Tools Required: Socket set, brake cleaner, torque wrench.
  • Check brake pads and rotors for wear:
    • Remove the wheel to access the brake components.
    • Measure the thickness of the brake pads; replace if below the manufacturer's minimum specification.
    • Inspect the rotors for grooves or excessive wear; replace if necessary.
  • If pads or rotors are worn, replace them:
    1. Remove the caliper bolts and slide the caliper off the rotor.
    2. Replace the brake pads and reinstall the caliper.
    3. Reinstall the wheel and torque to the manufacturer's specifications.
4. Inspect Brake Lines and Calipers
  • Tools Required: Wrench set, flashlight.
  • Examine brake lines for leaks or corrosion; replace any damaged lines.
  • Inspect brake calipers for proper operation; replace if they are sticking or leaking.
5. Test Brake Booster and Master Cylinder
  • Tools Required: Brake pedal tester (if available).
  • With the engine off, pump the brake pedal several times until it feels hard; then hold the pedal down.
  • Start the engine; the pedal should drop slightly if the brake booster is functioning. If it does not drop, the booster may need replacement.
  • Inspect the master cylinder for leaks and proper operation; replace if necessary.
