Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery to avoid any electrical issues.

2. Remove Wheel

Loosen lug nuts on the wheel using a lug wrench.
Raise the vehicle with a jack and secure it with jack stands.
Remove the wheel to access the brake assembly.

3. Remove Brake Caliper

Locate the caliper mounting bolts and remove them using a socket set.
Carefully slide the caliper off the brake rotor. Do not let it hang by the brake line; use a bungee cord to secure it.

4. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Clean the caliper bracket and apply brake grease to the backing of the new pads.
Install the new brake pads into the bracket.

5. Reassemble Components

Reattach the brake caliper over the new pads and secure it with the mounting bolts. Torque the bolts to manufacturer specifications.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower the Vehicle

Carefully lower the vehicle back to the ground and fully tighten the lug nuts in a crisscross pattern to ensure even pressure.

7. Test the Brakes

Reconnect the battery and pump the brake pedal several times to seat the new pads.
Perform a test drive to ensure proper brake function and listen for any unusual noises.
