Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to prevent movement.

2. Remove Wheel

Tools Required: Lug wrench, jack, jack stands.
Sub-steps:
1. Loosen the lug nuts slightly while the wheel is still on the ground.
2. Raise the vehicle with a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: C-clamp or brake caliper tool, torque wrench, socket set.
Sub-steps:
1. Remove the brake caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor and suspend it with a hook (do not let it hang by the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Use a C-clamp to compress the caliper piston back into the caliper housing.
5. Install new brake pads in the caliper bracket, ensuring proper orientation.
6. Reattach the caliper over the new pads and torque the caliper bolts to manufacturer specifications.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Torque wrench, socket set.
Sub-steps:
1. If the rotors are scored or warped, remove the rotor by taking off the retaining screws (if equipped) and sliding it off the hub.
2. Clean the hub surface to ensure a good fit for the new rotor.
3. Install the new rotor and secure it with the retaining screws.
4. Repeat the process on the other side if necessary.

5. Reassemble Components

Sub-steps:
1. Reinstall the wheel onto the hub and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands.
3. Torque the lug nuts to the manufacturer's specifications in a star pattern.
