Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a level surface and the parking brake is engaged.
  • Wear safety glasses and gloves.
2. Inspect and Replace Brake Fluid
  1. Locate the brake master cylinder reservoir.
  2. Remove the cap and inspect the fluid level; add new brake fluid if low.
    • Tools Required: Brake fluid (DOT 3 or DOT 4 as specified), funnel.
    • Safety Warnings: Avoid letting brake fluid contact painted surfaces as it can damage paint.
3. Bleed Brake Lines
  1. Start at the brake furthest from the master cylinder (usually the rear passenger side).
  2. Attach a clear plastic tube to the bleeder valve on the brake caliper and submerge the other end in a container with brake fluid.
  3. Have an assistant pump the brake pedal several times and hold it down.
  4. Open the bleeder valve to release air and fluid, then close the valve before the pedal is released.
  5. Repeat until no air bubbles are present in the fluid.
  6. Move to the next wheel and repeat the process in the order: rear passenger, rear driver, front passenger, front driver.
    • Tools Required: Brake bleeder kit or clear tubing, wrench for bleeder valve.
    • Safety Warnings: Ensure the brake fluid level does not drop too low during bleeding to prevent introducing air into the system.
4. Inspect and Replace Brake Components (if necessary)
  1. Remove the wheel to access the brake caliper.
  2. Inspect brake pads for thickness and rotors for scoring or warping. Replace if necessary.
    • Parts Required: Brake pads, rotors (if needed).
  3. Reassemble the brakes and wheel once inspections and replacements are complete.
