Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Remove Wheel

Using a lug wrench, loosen the lug nuts on the wheel.
Raise the vehicle with a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Remove Brake Caliper

Locate the caliper bolts (usually two) and remove them using a socket wrench.
Carefully slide the caliper off the rotor and support it using a bungee cord or rope to avoid straining the brake line.

4. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Clean the caliper bracket and apply brake grease to the contact points.
Install new brake pads ensuring they are properly seated.

5. Inspect and Clean Caliper Components

Check caliper slide pins for corrosion or dirt. Clean and lubricate as necessary.
Inspect the caliper piston and ensure it moves freely; if stuck, consider replacing the caliper.

6. Reassemble Components

Reattach the caliper over the new brake pads and tighten the caliper bolts to the manufacturer’s specified torque (consult the service manual for the exact value).
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Remove the jack stands and lower the vehicle back to the ground.
Tighten the lug nuts to the specified torque in a crisscross pattern.
