Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the parking brake is engaged.
  • Disconnect the battery to prevent any electrical issues during repairs.
2. Inspect and Replace Brake Fluid
  • Locate the master cylinder reservoir.
  • Remove the cap and check the brake fluid level. If low, top off with the manufacturer-recommended brake fluid.
  • If the fluid appears dirty or contaminated, proceed to replace the brake fluid.
    • Tools Required: Brake fluid, funnel, clean rags.
    • Sub-steps:
      • Use a turkey baster to remove old brake fluid from the reservoir.
      • Refill with fresh brake fluid until the appropriate level is reached.
      • Bleed the brake lines to remove air from the system (see Bleeding Brakes below).
3. Bleed the Brake Lines
  • Start from the farthest brake from the master cylinder and work towards the nearest.
  • Attach a clear hose to the bleeder screw on the brake caliper.
    • Tools Required: Brake bleeder kit, clear hose, wrench.
    • Sub-steps:
      • Have an assistant pump the brake pedal several times and hold it down.
      • Open the bleeder screw to let air and old fluid escape; close it before the assistant releases the pedal.
      • Repeat until only clean fluid flows through the hose.
      • Check fluid levels frequently during the process to avoid introducing more air.
4. Inspect Brake Pads and Rotors
  • Remove the wheel to access the brake assembly.
  • Visually inspect brake pads for thickness and even wear.
  • Check rotors for scoring, warping, or other damage.
    • Tools Required: Jack and jack stands, socket set.
    • Sub-steps:
      • If pads are worn below the manufacturer’s specification, replace them.
      • If rotors are damaged or warped, replace or resurface them as necessary.
5. Reassemble and Test
  • Reinstall the wheel and lower the vehicle.
  • Reconnect the battery.
  • Test the brake pedal for firmness and ensure the brake warning light is off.
