why does my Honda Pilot YF4 (2023-Present) brake pedal feel soft?

Solution

1. Preparation

• Gather tools and materials: wrench set, brake fluid, brake cleaner, OBD-II scanner.
• Ensure the vehicle is parked on a level surface with the parking brake engaged.

2. Inspect and Top Off Brake Fluid

• Check the brake fluid reservoir level. If low, add the manufacturer's recommended brake fluid (DOT 3 or DOT 4).
• If the fluid is contaminated, proceed to flush the brake system.

3. Check for Leaks

• Visually inspect brake lines, hoses, and calipers for leaks.
• If leaks are found, replace the damaged components as needed.

4. Brake System Bleeding

• Use a brake bleeder kit:
  • Attach the bleeder hose to the brake bleeder valve on each caliper.
  • Have an assistant pump the brake pedal several times and hold it down.
  • Open the bleeder valve to release air and fluid, then close it before the pedal is released.
  • Repeat until no air bubbles are present in the fluid.
• Repeat for all four wheels, starting with the wheel farthest from the master cylinder.

5. Inspect Brake Components

• Remove the wheel and inspect brake pads and rotors for wear.
• If pads are worn below the manufacturer's specifications, replace them.
• Check the condition of the rotors; if warped or excessively worn, replace them.
