Solution
1. Preparation
  • Gather tools and parts required.
  • Make sure the vehicle is parked on a level surface and secure with wheel chocks.
  • Wear safety gloves and goggles.
2. Check and Refill Brake Fluid
  • Locate the brake fluid reservoir under the hood.
  • Remove the cap and check the fluid level; it should be between the minimum and maximum marks.
  • If low, add the appropriate type of brake fluid (usually DOT 3 or DOT 4) as specified in the owner's manual.
3. Inspect and Repair Brake Lines
  • Inspect all brake lines for signs of corrosion or cracks.
  • Tighten any loose connections and replace any damaged hoses or lines.
  • If leaks are found, replace the affected components and ensure proper sealing.
4. Bleed the Brake System
  • Start with the brake farthest from the master cylinder (usually the right rear).
  • Use a brake bleeder kit or a helper to press the brake pedal while you open the bleeder valve to allow air and fluid to escape.
  • Close the valve before releasing the brake pedal and repeat until no air bubbles are visible in the fluid.
  • Move to the left rear, right front, and finally left front, repeating the process.
5. Replace Brake Pads and Rotors (if necessary)
  • If brake pads are worn down, remove the wheel and caliper.
  • Remove the old pads and inspect the rotors for damage.
  • Replace worn pads with new ones and resurface or replace rotors as needed.
  • Reassemble the caliper and wheel, ensuring all bolts are torqued to manufacturer specifications.
