Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the parking brake is engaged.
  • Wear safety gloves and goggles.
2. Check and Refill Brake Fluid
  • Locate the master cylinder reservoir and inspect the fluid level.
  • If low, add the specified brake fluid (DOT 3 or DOT 4 as per owner's manual).
  • Check for leaks after filling.
3. Inspect and Repair Brake Lines
  • Visually inspect all brake lines for corrosion or damage.
  • Tighten any loose fittings and replace damaged lines.
  • If leaks are found, replace the affected sections of the brake line.
4. Replace Brake Pads and Rotors (if necessary)
  • Remove the wheel to access the brake assembly.
  • Remove caliper bolts and slide the caliper off the rotor.
  • Replace worn brake pads and inspect rotors for scoring or warping.
  • If necessary, replace the rotors and ensure they are properly torqued.
5. Bleed the Brake System
  • Start by removing any air from the brake lines.
  • Use a brake bleeder kit or a helper to pump the brake pedal while opening the bleeder valve on each caliper.
  • Continue until a steady stream of fluid with no air bubbles is observed.
  • Ensure the master cylinder is topped off during this process.
6. Reassemble and Test
  • Reinstall the caliper and wheel, ensuring all components are torqued to specifications.
  • Test the brake pedal for firmness before driving the vehicle.
