Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
  • Disconnect the battery to prevent electrical shorts during repairs.
2. Check and Refill Brake Fluid
  • Locate the brake fluid reservoir under the hood.
  • Remove the cap and check the fluid level, adding the appropriate type of brake fluid (DOT 4) if low.
  • Reinstall the cap securely.
3. Inspect Brake Components
  • Remove the wheel to access the brake assembly.
  • Inspect the brake pads for thickness; replace if worn down to less than 3mm.
  • Check the brake rotors for scoring or warping; replace if necessary.
  • Ensure the brake lines are intact and free of leaks.
4. Replace Worn Components
  • If brake pads need replacement:
    • Remove the caliper bolts using a socket set.
    • Slide the caliper off the rotor and support it with a bungee cord (do not hang it by the brake line).
    • Remove the old brake pads and install new ones.
    • Reattach the caliper and torque the bolts to the manufacturer's specification (usually around 25-30 Nm).
  • If rotors are damaged, remove them by unbolting from the hub and replace with new ones.
5. Reconnect Battery and Test Drive
  • Reconnect the battery.
  • Start the vehicle and check if the brake warning light is still illuminated.
  • Conduct a test drive to ensure brakes function properly without warning lights.
