why is my Renault Clio V (2019-Present) brake pedal going to the floor

Solution

1. Preparation

• Gather all tools and parts needed for the repair.
• Ensure the vehicle is parked on a level surface, and use wheel chocks to prevent movement.
• Wear safety glasses and gloves for protection.

2. Check and Refill Brake Fluid

• Locate the brake fluid reservoir under the hood.
• If the fluid is low, top it up with the manufacturer-recommended brake fluid (DOT 4).
• Inspect the reservoir cap for proper sealing.

3. Inspect and Repair Leaks

• Visually check all brake lines and connections for signs of fluid leakage.
• If leaks are found, replace the damaged brake lines or fittings as necessary.
• Tighten any loose connections to prevent further leaks.

4. Replace Brake Pads and Discs (if necessary)

• Remove the wheel using a socket set.
• Unbolt the brake caliper and support it without putting stress on the brake line.
• Remove the old brake pads and inspect the brake discs for wear.
• If the discs are worn beyond specifications, replace them.
• Install new brake pads according to manufacturer specifications.

5. Inspect and Replace Master Cylinder (if necessary)

• Disconnect the battery to ensure safety.
• Remove the brake lines from the master cylinder carefully.
• Unscrew the master cylinder from its mounting bracket.
• Install the new master cylinder and reconnect the brake lines securely.
• Reconnect the battery.

6. Bleed the Brake System

• Using a brake bleeder kit, bleed each brake starting from the furthest wheel from the master cylinder.
• Ensure there are no air bubbles in the fluid until clear fluid flows through each line.
• Recheck the brake fluid level and top off if needed.
