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

Solution

1. Preparation

• Gather all necessary tools and parts.
• Ensure the vehicle is parked on a level surface and engage the parking brake.
• Wear safety gloves and goggles.

2. Inspect and Replace Brake Fluid

• Tools Required: Brake fluid, funnel, lint-free cloth
• Check the brake fluid level in the master cylinder reservoir.
• If low, add the recommended type of brake fluid (typically DOT 3 or DOT 4).
• If the fluid is dark or contaminated, it should be replaced.
• Drain old brake fluid by opening the bleeder valves on each brake caliper and allowing it to flow into a container.
• Refill the master cylinder with new brake fluid.

3. Inspect and Replace Brake Lines

• Tools Required: Wrench set, replacement brake line
• Examine brake lines for any visible wear or leaks.
• If damaged, use a wrench to disconnect the affected line.
• Replace with a new brake line, ensuring all connections are tight and free of leaks.

4. Bleed the Brakes

• Tools Required: Brake bleeder kit, clear tubing, container
• Attach clear tubing to the bleeder valve on the farthest brake caliper from the master cylinder.
• Have an assistant pump the brake pedal several times and hold it down.
• Open the bleeder valve to release air and fluid into the container.
• Close the valve and repeat until no air bubbles are seen in the fluid.
• Repeat this process for each brake caliper, moving closer to the master cylinder.

5. Inspect and Replace Brake Pads/Rotors

• Tools Required: Jack and jack stands, socket set
• Lift the vehicle and remove the wheel to access the brake assembly.
• Inspect the brake pads for thickness; if below 3mm, replace them.
• Check the brake rotors for scoring or warping; replace if necessary.
