Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, safety glasses, gloves.
Raise the vehicle and secure it on jack stands.
Remove the wheel using the lug wrench.

2. Inspect Brake Components

Check Brake Pads:
- Remove the caliper bolts using the socket set.
- Carefully slide the caliper off the rotor.
- Inspect the brake pads for thickness; replace if less than 3mm.
Check Brake Rotors:
- Inspect the rotor surface for scoring or warping.
- If damaged, replace the rotors.

3. Clean and Lubricate

Clean the brake components using brake cleaner.
Apply brake grease to the caliper slide pins and the back of the brake pads to ensure smooth operation.

4. Reassemble Components

Reinstall the caliper over the new pads and rotor.
Torque the caliper bolts to the manufacturer’s specifications (usually around 25-30 ft-lbs).
Reinstall the wheel and torque the lug nuts to the specified value.

5. Final Checks

Lower the vehicle and pump the brake pedal to seat the pads against the rotor.
Test drive the vehicle to ensure the grinding noise has stopped.
