Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the battery to prevent any electrical issues.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel
Inspect the brake fluid level in the master cylinder reservoir.
If low, add the appropriate type of brake fluid (usually DOT 4 for Renault).
Ensure the reservoir cap is securely replaced.

3. Inspect and Repair Leaks

Tools Required: Wrench set, brake line repair kit
Examine brake lines, calipers, and connections for leaks.
If leaks are found, replace damaged brake lines or seals using the repair kit.
Tighten any loose connections with the appropriate torque specifications.

4. Bleed the Brake Lines

Tools Required: Brake bleeder kit, wrench
Starting from the wheel farthest from the master cylinder, open the bleeder valve.
Have an assistant press the brake pedal several times until no air bubbles are observed in the fluid.
Close the bleeder valve and repeat for each wheel, moving closer to the master cylinder.
Check the brake fluid level frequently and top up as necessary.

5. Inspect and Replace Brake Components

Tools Required: Jack and jack stands, socket set, torque wrench
Remove the wheel to access brake components.
Inspect brake pads and rotors for wear; replace if they are worn down.
Ensure that the caliper is functioning correctly and not sticking.
Reinstall the wheel and torque to manufacturer specifications.
