why is my Honda CR-V's brake pedal going to the floor

Solution

1. Preparation

• Gather required tools and parts.
• Ensure the vehicle is parked on a level surface and engage the parking brake.
• Disconnect the negative battery terminal for safety.

2. Check Brake Fluid Level

• Open the master cylinder reservoir cap.
• If the fluid is low, top it off with the manufacturer-recommended brake fluid (e.g., DOT 3 or DOT 4).
• Inspect for leaks after topping off.

3. Inspect and Repair Leaks

• Examine all brake lines, hoses, and connections for leaks.
• Replace any damaged or corroded brake lines or hoses.
• If the master cylinder is leaking, it must be replaced.

4. Bleed the Brake System

• Reconnect the negative battery terminal.
• Use a brake bleeder kit or have an assistant pump the brake pedal while you open and close the bleeder valves on each caliper, starting from the farthest from the master cylinder (usually the right rear) and moving closer.
• Check the brake fluid level frequently and top it off as needed.

5. Inspect Brake Components

• Remove the wheel to access the brake components.
• Check brake pads for thickness; replace if worn below the manufacturer's specifications.
• Inspect rotors for scoring or warping; replace if necessary.

6. Reassemble and Test

• Reinstall the wheel and lower the vehicle.
• Test the brake pedal feel before driving; it should be firm.
• Conduct a test drive to ensure proper brake function.
