Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and securely lifted with jack stands.
Disconnect the battery to avoid any electrical issues during the repair.

2. Remove Wheel Assembly

Use a lug wrench to loosen and remove the lug nuts from the wheel.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts using a socket set and carefully detach the brake caliper.
- Support the caliper using a bungee cord or hang it from the suspension to avoid straining the brake line.
- Remove the old brake pads from the caliper bracket.
- Inspect the caliper slides and lubricate them if necessary.
- Install new brake pads, ensuring they are oriented correctly.
Tools Required: Socket set, bungee cord, brake pad grease.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
- Check the brake rotors for scoring or excessive wear.
- If replacement is required, remove the rotor by unscrewing the retaining screws (if any) and sliding it off the hub.
- Install the new rotor, ensuring it is seated properly.
Tools Required: Torque wrench, socket set.

5. Reassemble Brake Components

Reattach the brake caliper over the new brake pads.
Torque the caliper bolts to the manufacturer's specifications (typically around 20-25 ft-lbs, but verify with service manual).
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle and tighten the lug nuts in a crisscross pattern to the manufacturer's torque specifications.
Reconnect the battery.
