what are common causes of Honda CR-V Fifth Generation (2017-2022) brake pedal going to the floor

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
• Wear safety glasses and gloves.

2. Check Brake Fluid Level

• Remove the cap from the master cylinder reservoir.
• Inspect the fluid level; if low, add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner’s manual).
• Look for signs of contamination or discoloration.

3. Inspect and Repair Leaks

• Visually inspect all brake lines and connections for leaks.
• Replace any damaged or corroded brake lines.
• If leaks are found at the calipers, replace the caliper seals or the caliper itself if necessary.

4. Brake Pad and Rotor Replacement

• Remove the wheel and tire assembly using a lug wrench.
• Unbolt the brake caliper and suspend it using a wire to avoid straining the brake line.
• Remove the old brake pads and inspect the rotors for scoring or warping.
• Replace the brake pads and resurface or replace the rotors as needed.
• Reassemble the caliper and wheel.

5. Bleed the Brake System

• Use a brake bleeder kit to remove air from the brake lines.
• Start with the wheel farthest from the master cylinder and work towards the nearest.
• Ensure the brake fluid level remains full during the process to avoid introducing more air into the system.
