Solution

1. Preparation

Gather tools: jack and jack stands, socket set, torque wrench, brake cleaner, and safety goggles.
Park the vehicle on a level surface and ensure it is in "Park" mode.
Disconnect the negative battery terminal to prevent electrical issues.

2. Lift Vehicle

Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel corresponding to the affected brake pads.

3. Remove Brake Caliper

Using a socket set, remove the caliper mounting bolts.
Carefully slide the caliper off the rotor and support it with a bungee cord or strap (do not let it hang by the brake line).
Inspect the caliper for signs of wear or sticking.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Examine the surface of the brake rotor for scoring or uneven wear; replace if necessary.
Install new brake pads, ensuring they are properly seated in the caliper bracket.
Apply anti-squeal lubricant on the back of the pads to prevent noise.

5. Reinstall Brake Caliper

Reposition the caliper over the new brake pads.
Tighten the caliper mounting bolts to the manufacturer’s specified torque (usually around 25-35 lb-ft).
Reinstall the wheel and lower the vehicle.

6. Brake System Check

Reconnect the negative battery terminal.
Pump the brake pedal several times to seat the pads against the rotor.
Check brake fluid level and top off if necessary.
