Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical issues while working on the braking system.

2. Brake Fluid Level Check and Top-Up

Locate the brake fluid reservoir (usually near the driver's side).
Remove the cap and check the fluid level; it should be between the minimum and maximum marks.
If low, add the appropriate brake fluid (DOT 4 for Renault Clio V).

3. Inspect and Replace Brake Pads

Tools Required: Socket set, brake pad spreader, torque wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake calipers.
Use the socket set to remove the caliper bolts.
Carefully slide the caliper off and support it without putting stress on the brake line.
Remove the old brake pads and inspect the rotors for scoring or damage.
Install new brake pads, ensuring proper orientation and fit.
Reattach the caliper and torque bolts to the manufacturer’s specifications (typically 25-30 Nm).

4. Inspect Brake Lines and Components

Check all visible brake lines for signs of leaks or damage.
If leaks are found, replace the affected brake line or component as necessary.
Ensure that all connections are tight and secure.

5. Reconnect Battery and Reset Warning Light

Reconnect the battery terminals.
Start the vehicle and check if the brake warning light remains illuminated.
If it does, you may need to reset the system using an OBD-II scanner.
