Solution
1. Preparation
  • Ensure the vehicle is on a level surface and secure it with wheel chocks.
  • Gather necessary tools and parts.
  • Wear safety goggles and gloves for protection.
2. Inspect and Repair Leaks
  • Inspect Brake Lines and Hoses:
    • Use a flashlight to check for leaks along the brake lines and connections.
    • Tools Required: Wrench set, flashlight.
  • Repair or Replace:
    • If any leaks are found, replace damaged brake lines or hoses.
    • Use flare nut wrenches to avoid rounding the nuts during removal.
3. Check and Replace Brake Fluid
  • Drain Old Brake Fluid:
    • Open the brake fluid reservoir cap and drain the old fluid using a syringe.
    • Dispose of the old fluid properly.
  • Add New Brake Fluid:
    • Fill the reservoir with the recommended brake fluid type (DOT 3 or DOT 4, depending on the model).
    • Tools Required: Syringe, new brake fluid.
4. Bleed the Brake System
  • Prepare for Bleeding:
    • Attach a clear tube to the bleeder valve on each brake caliper.
    • Place the other end of the tube in a container to catch old fluid.
  • Bleed the Brakes:
    • Start with the brake furthest from the master cylinder (usually the right rear).
    • Have an assistant pump the brake pedal several times and hold it down.
    • Open the bleeder valve slightly to release air and fluid, then close it before the pedal is released.
    • Repeat this process until no air bubbles are present in the fluid.
    • Tools Required: Bleeder kit or tubing, wrench.
5. Test the Brake System
  • Check Brake Function:
    • After bleeding, pump the brake pedal several times to ensure it feels firm.
    • Test drive the vehicle at low speeds in a safe area to verify proper braking function.
