Solution
1. Preparation
  • Gather necessary tools and parts.
  • Park the vehicle on a level surface and engage the parking brake.
  • Disconnect the negative battery terminal.
2. Inspect and Replace Brake Fluid
  1. Open the hood and locate the brake master cylinder.
  2. Check the fluid level; if low, add the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
  3. If the fluid is dark or contaminated, proceed to replace it.
    • Use a turkey baster to remove old fluid from the reservoir.
    • Refill with new brake fluid to the proper level.
3. Inspect Brake Lines and Components
  1. Look for leaks in the brake lines, calipers, and wheel cylinders.
  2. If leaks are found, replace the damaged component(s).
  3. Inspect brake pads and rotors; replace if worn beyond specifications (pads less than 3mm thickness).
4. Bleed the Brake System
  1. Reconnect the negative battery terminal.
  2. Begin bleeding from the wheel farthest from the master cylinder (usually the right rear).
  3. Use a brake bleeder kit or have an assistant pump the brake pedal.
    • Open the bleeder valve on the caliper to release air and old fluid.
    • Close the valve before the pedal is released.
  4. Repeat this process at each wheel (right rear, left rear, right front, left front) until clear fluid without bubbles flows out.
5. Test Brake Booster
  1. With the engine running, press the brake pedal; it should feel firm.
  2. If the pedal sinks or feels soft, the brake booster may be faulty and require replacement.
