Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery for safety.

2. Inspect and Repair Leaks

Tools Required: Wrench set, brake line wrench
Visually inspect brake lines, calipers, and master cylinder for leaks.
If leaks are found, tighten fittings or replace damaged lines/components as necessary.

3. Refill Brake Fluid

Tools Required: Brake fluid funnel, clean cloth
Open the brake fluid reservoir cap carefully.
Using a funnel, add the recommended brake fluid type (usually DOT 4 for Renault).
Fill to the maximum level indicated on the reservoir.

4. Bleed the Brake System (if necessary)

Tools Required: Brake bleeder kit, wrench for bleeder screws
Start with the brake furthest from the master cylinder (usually the right rear).
Open the bleeder screw and have an assistant press the brake pedal.
Close the bleeder screw before the pedal reaches the floor, then repeat until no air bubbles are visible in the fluid.
Repeat for all brakes in the correct order (right rear, left rear, right front, left front).

5. Final Checks

Tools Required: Torque wrench
Ensure all components are securely fastened and the brake fluid cap is replaced.
Reconnect the battery.
