Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent any electrical issues during repair.

2. Check and Refill Brake Fluid

Sub-steps:
- Locate the brake fluid reservoir and remove the cap.
- Inspect the fluid level; if low, refill with the recommended brake fluid type (DOT 4 for Renault).
- Replace the cap securely.

3. Inspect and Repair Leaks

Sub-steps:
- Visually inspect brake lines, calipers, and the master cylinder for signs of fluid leakage.
- If leaks are found, replace the damaged component (e.g., brake line, caliper, or master cylinder).
- Ensure all fittings are tight and secure.

4. Bleed the Brake System

Sub-steps:
- Begin at the farthest wheel from the master cylinder, typically the right rear wheel.
- Attach a clear hose to the bleeder valve and place the other end in a container with brake fluid.
- Open the bleeder valve and have an assistant press the brake pedal slowly several times until a steady stream of fluid without air bubbles flows out.
- Close the bleeder valve and repeat the process for the left rear, right front, and left front brakes, ensuring to keep the fluid reservoir filled throughout.

5. Test Brake Functionality

Sub-steps:
- Reconnect the negative battery terminal.
- Start the engine and pump the brake pedal several times to build pressure.
- Test the brake pedal feel and response during a slow drive in a safe area.
