Solution

1. Preparation

Gather tools and parts required.
Ensure vehicle is parked on a level surface and secure the vehicle with wheel chocks.
Disconnect the battery to avoid any electrical issues.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts with a socket wrench.
- Slide the caliper off the rotor and support it with a bungee cord (do not let it hang from the brake line).
- Remove the old brake pads from the caliper bracket.
- Inspect the caliper and bracket for any debris or damage.
- Install new brake pads, ensuring they are properly seated in the bracket.

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are damaged or excessively worn, remove them by unbolting from the hub.
Clean the hub surface with brake cleaner.
Install new rotors by securing them in place with the bolts to the manufacturer’s torque specifications.

5. Reassemble Braking Components

Reattach the caliper over the new brake pads and secure it with the caliper bolts.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer’s specifications.

6. Reconnect Battery

Reconnect the battery terminal securely.

7. Test Brakes

Pump the brake pedal to seat the pads properly before road testing.
