Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Disconnect the battery to prevent electrical issues during the repair.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper bolts with a socket wrench.
Carefully slide the caliper off the rotor and suspend it using a bungee cord (avoid hanging it by the brake line).
Inspect the brake pads for wear; replace if uneven wear is noted.
- Sub-steps:
  - Remove the old brake pads from the caliper bracket.
  - Apply brake grease to the backing of the new pads and install them into the bracket.

4. Inspect and Replace Caliper (if necessary)

Check if the caliper is functioning correctly; replace if it's sticking or damaged.
- Sub-steps:
  - Disconnect the brake line from the caliper (ensure to have a drip pan for fluid).
  - Remove the caliper from the bracket and install the new caliper.
  - Reconnect the brake line and torque to manufacturer specifications.

5. Reassemble

Reattach the caliper to the bracket and secure with bolts, torquing to specifications.
Reinstall the wheel and torque lug nuts to specification.
Lower the vehicle and reconnect the battery.
