why does my Honda Accord Eleventh Generation (2023-present) brake pedal feel spongy

Solution

1. Preparation

• Gather tools and protective gear.
• Ensure the vehicle is parked on a flat surface and the ignition is off.
• Use wheel chocks to prevent the vehicle from rolling.

2. Check and Refill Brake Fluid

• Open the hood and locate the brake master cylinder reservoir.
• Remove the cap and check the brake fluid level.
• If low, add the recommended type of brake fluid (DOT 3 or DOT 4).

3. Inspect and Repair Leaks

• Visually inspect brake lines, calipers, and the master cylinder for leaks.
• If leaks are found, replace the affected components (brake lines, calipers, or master cylinder).

4. Bleed the Brake System

• Attach a clear hose to the bleeder valve on each brake caliper.
• Have an assistant press the brake pedal slowly while you open the bleeder valve to release air and fluid.
• Close the valve before your assistant releases the brake pedal.
• Repeat until no air bubbles are present, and fluid runs clear.
• Check the fluid level in the master cylinder during this process and refill as necessary.

5. Inspect Brake Components

• Remove the wheel to access the brake assembly.
• Check brake pads for thickness; replace if worn below the manufacturer’s specifications.
• Inspect brake rotors for wear or damage; resurface or replace if necessary.

6. Test Brake Booster

• Start the vehicle and pump the brake pedal several times to build vacuum.
• Press the brake pedal and hold it; if it sinks to the floor, the brake booster may be faulty and require replacement.
