Solution
1. Preparation
  • Ensure the vehicle is parked on a level surface and the parking brake is engaged.
  • Gather necessary tools and parts.
2. Inspect and Replace Brake Fluid
  • Tools Required: Brake fluid, funnel, rag
  • Check the brake fluid level; if low, top it up with the manufacturer-recommended brake fluid.
  • If the fluid is dirty or contaminated, perform a brake fluid flush:
    • Remove the brake fluid reservoir cap.
    • Use a suction tool to remove old fluid from the reservoir.
    • Refill with new brake fluid and bleed the brakes to remove air.
3. Brake Booster Inspection
  • Tools Required: Wrench set, vacuum gauge (optional)
  • Inspect the vacuum line connected to the brake booster for cracks or disconnections; replace if necessary.
  • Check the brake booster:
    • With the engine off, press the brake pedal several times to deplete the vacuum.
    • Start the engine; the brake pedal should move down slightly indicating the brake booster is functioning properly.
    • If not, replace the brake booster.
4. Brake Component Inspection
  • Tools Required: Socket set, torque wrench
  • Remove the wheel to access the brake components.
  • Inspect brake pads and rotors for wear; replace if the pads are below the minimum thickness or if rotors are damaged.
  • Ensure calipers are functioning correctly and are not seized.
5. Reassemble and Test
  • Reinstall the wheel and torque the lug nuts to the manufacturer’s specifications.
  • Perform a test drive to ensure proper brake function.
