Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the engine is off.
  • Engage the parking brake for added safety.
2. Check Brake Fluid Level
  • Open the hood and locate the master cylinder reservoir.
  • Inspect the fluid level; if low, add the appropriate brake fluid (DOT 4).
  • If the fluid is discolored, consider replacing it entirely.
3. Inspect for Leaks
  • Visually inspect brake lines and connections for any signs of leakage.
  • If leaks are found, replace the affected brake lines or components.
4. Brake Pad and Rotor Inspection
  • Remove the wheels using a socket set.
  • Check the thickness of the brake pads; if they are below the minimum thickness (generally 3mm), replace them.
  • Inspect the rotors for warping or scoring; replace if necessary.
5. Brake Booster and Master Cylinder Check
  • Disconnect the brake booster vacuum line and inspect for vacuum leaks.
  • Check the master cylinder for any signs of fluid seepage or pressure loss.
  • If the master cylinder is defective, replace it and bleed the brake system.
6. Bleed the Brake System
  • Use a brake bleeder kit to remove air from the brake lines.
  • Start at the farthest wheel from the master cylinder and work towards the closest.
  • Ensure the brake fluid reservoir is kept topped up during the process.
