Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
  • Disconnect the negative battery terminal to prevent electrical shorts.
2. Check Brake Fluid Level
  • Locate the brake fluid reservoir (usually near the master cylinder).
  • Remove the cap and visually inspect the fluid level; if low, top off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
  • Reinstall the cap securely.
3. Inspect Brake Components
  • Remove the wheel to access the brake assembly.
  • Check the brake pads for thickness; replace if below 3mm.
  • Inspect the rotors for scoring or warping; replace if necessary.
  • Examine brake lines for any signs of leaks or corrosion.
4. Replace Brake Pads and/or Rotors (if needed)

  • Brake Pad Replacement:

    • Remove the caliper bolts and lift the caliper off the rotor.
    • Remove old brake pads and install new ones, ensuring they are properly seated.
    • Compress the caliper piston using a brake caliper tool.
    • Reattach the caliper and torque bolts to manufacturer specifications (typically 22-30 lb-ft).

  • Rotor Replacement:

    • If rotors are worn, remove them by unbolting the caliper bracket.
    • Replace the rotor with a new one, ensuring it is clean and properly aligned.
    • Reattach the caliper bracket and torque the bolts to specification.
5. Reassemble and Test
  • Reinstall the wheel and lower the vehicle.
  • Reconnect the negative battery terminal.
  • Start the vehicle and pump the brake pedal to establish brake pressure.
