why does my Renault Clio V (2019-Present) make a grinding noise when braking?

Solution

1. Preparation

• Tools Needed: Jack, jack stands, lug wrench, socket set, brake cleaner, and safety goggles.
• Safety Warning: Ensure the vehicle is on a flat surface and securely raised using jack stands before beginning any work.

2. Remove Wheel

• Loosen the lug nuts using a lug wrench.
• Raise the vehicle with a jack and secure it with jack stands.
• Remove the lug nuts completely and take off the wheel to access the brake components.

3. Inspect Brake Components

• Brake Pads: Remove the caliper by unscrewing the bolts holding it in place. Slide the caliper off the rotor and inspect the pads for thickness; replace if they are below the manufacturer's minimum specification.
• Brake Rotors: Check the rotors for any signs of scoring or warping. If damaged, remove the rotors by unscrewing the retaining screws and replace them with new ones.
• Caliper Check: Inspect the caliper for proper movement and any signs of sticking. If necessary, lubricate the sliding pins or replace the caliper.

4. Clean and Reassemble

• Use brake cleaner to clean the rotor and caliper components to remove any brake dust or debris.
• Reinstall the caliper over the new or cleaned rotor and secure it with bolts, ensuring proper torque as per manufacturer specifications.
• Reinstall the wheel, tighten the lug nuts in a criss-cross pattern, and lower the vehicle.

5. Test Brakes

• Pump the brake pedal several times to ensure the brake pads seat properly against the rotors.
• Check the brake fluid level again and top off if necessary.
