Solution

1. Preparation

Gather necessary tools and parts.
Ensure vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to avoid electrical issues while working on the braking system.

2. Inspect and Replace Brake Fluid

Sub-steps:
1. Open the master cylinder reservoir and check brake fluid level.
2. If low, top off with the recommended brake fluid type (usually DOT 4 for Renault vehicles).
3. Bleed the brake lines to remove air bubbles using a brake bleeder kit.
  - Start with the wheel furthest from the master cylinder (usually the right rear).
  - Attach the bleeder kit and open the bleeder valve while an assistant presses the brake pedal.
  - Close the valve before the pedal is released to prevent air from entering.
  - Repeat until clear fluid without bubbles is emitted.
4. Clean any spilled brake fluid immediately as it can damage paint.

3. Brake Component Inspection and Replacement

Sub-steps:
1. Remove the wheel to access brake components.
2. Inspect brake pads for wear; replace if thickness is below 3mm.
3. Check rotors for grooving or scoring; replace if necessary.
4. Inspect brake calipers for leaks; replace seals or calipers if damaged.
5. Reinstall all components and torque wheel nuts to the manufacturer's specifications (often around 100 Nm for Renault).

4. System Check

Sub-steps:
1. Reconnect the battery.
2. Start the vehicle and press the brake pedal several times to check for firmness.
3. Test drive the vehicle to ensure brakes operate effectively.
