Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is on a flat surface and secure it with wheel chocks.
  • Disconnect the negative battery terminal to avoid electrical issues.
2. Inspect and Replace Brake Fluid
  • Remove the master cylinder cap and check the brake fluid level.
  • If low, add manufacturer-recommended brake fluid (DOT 3 or DOT 4).
  • If fluid is contaminated (dark or has particles), proceed to flush the brake system.
3. Inspect and Repair Brake Lines
  • Visually inspect brake lines for cracks or leaks.
  • Tighten any loose connections.
  • Replace any damaged brake lines using a flare wrench and ensure proper torque (typically 15-20 ft-lbs).
4. Replace Brake Pads and Rotors (if necessary)
  • Remove the wheel and tire to access the brake components.
  • Remove the caliper bolts and slide the caliper off the rotor.
  • Remove the old brake pads and inspect the rotor for scoring or damage.
  • If necessary, replace the rotor by removing the rotor retaining screws and sliding it off.
  • Install new brake pads and rotor, ensuring proper alignment and torque (caliper bolts typically 25-30 ft-lbs).
5. Bleed the Brake System
  • Refill the master cylinder with fresh brake fluid.
  • Begin bleeding at the farthest brake from the master cylinder, typically the right rear wheel, and move to the closest (left front).
  • Use a brake bleeder kit or have an assistant pump the brake pedal while you open and close the bleeder valve until no air bubbles are present.
  • Repeat for each wheel until the brake pedal feels firm.
