Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
  • Wear safety glasses and gloves.
2. Check and Replenish Brake Fluid
  • Locate the master cylinder reservoir.
  • Remove the cap and inspect the brake fluid level.
  • If low, add the recommended brake fluid type (usually DOT 3 or DOT 4).
  • Replace the cap securely.
3. Inspect Brake Lines and Hoses
  • Visually inspect all brake lines and hoses for signs of leaks or cracks.
  • If leaks are found, replace the damaged sections of the brake line or hose.
  • Use a line wrench to prevent rounding off fittings.
4. Bleed the Brake System
  • Start at the wheel farthest from the master cylinder (typically the right rear).
  • Attach a clear hose to the bleeder valve and place the other end in a container.
  • Have an assistant pump the brake pedal several times, then hold it down.
  • Open the bleeder valve to release air and fluid, then close it before the pedal is released.
  • Repeat for each wheel in the order: right rear, left rear, right front, left front.
5. Replace Brake Pads and Rotors (if necessary)
  • Remove the wheel to access the brake components.
  • Remove the caliper bolts using a socket.
  • Slide the caliper off the rotor and support it without straining the brake line.
  • Replace worn brake pads and, if necessary, the rotor.
  • Reinstall the caliper and torque the bolts to the manufacturer's specifications.
