Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Disconnect the battery to avoid electrical shorts.

2. Remove Wheel

Using a socket set, loosen the lug nuts while the vehicle is still on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely, and take off the wheel.

3. Inspect and Replace Brake Pads

Locate the brake caliper and remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the brake rotor without stretching the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper bracket and clean any debris or rust from its surface.
Install new brake pads (ensure they are compatible with the Clio V) into the caliper bracket.
Apply brake grease to the back of the pads to prevent noise.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotors for any deep grooves or warping.
If rotors are damaged, remove the caliper bracket bolts and take off the bracket.
Remove the old rotor; if rusted, use a hammer to tap around the edges gently.
Install new rotors, ensuring they are seated correctly on the hub.
Reattach the caliper bracket and torque the bolts to manufacturer specifications.

5. Reassemble and Test

Reinstall the caliper over the new pads and torque the caliper bolts.
Reattach the wheel and torque the lug nuts to manufacturer specifications.
Lower the vehicle and reconnect the battery.
Pump the brake pedal several times to seat the new pads and restore brake pressure.
