Solution

1. Preparation

Gather necessary tools and parts.
Ensure vehicle is on a flat surface and secure it with wheel chocks.
Disconnect the battery if electrical components will be accessed.

2. Remove Wheel

Tools Required: Jack and jack stands, lug wrench.
Sub-steps:
1. Loosen lug nuts slightly before lifting the vehicle.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the wheel by fully unscrewing the lug nuts.

3. Inspect and Replace Brake Rotors

Tools Required: Torque wrench, socket set, brake cleaner.
Sub-steps:
1. Remove the brake caliper by unscrewing the mounting bolts and hanging it securely (do not stretch the brake line).
2. Remove the brake pads from the caliper bracket.
3. Unbolt and remove the rotor. Clean the hub surface with brake cleaner.
4. Install new rotors, ensuring they are properly seated.
5. Reinstall brake pads and caliper, torque caliper bolts to manufacturer specifications.

Tools Required: Brake pad spreader, torque wrench.
Sub-steps:
1. If pads are worn unevenly, replace them with new pads.
2. Compress the caliper piston using a brake pad spreader.
3. Install new brake pads in the caliper bracket.
4. Reinstall the caliper and torque bolts to specifications.

5. Check Suspension Components

Tools Required: Torque wrench, pry bar.
Sub-steps:
1. Visually inspect all suspension components for wear or damage.
2. Replace any worn tie rods, control arms, or bushings as necessary.
3. Reassemble components, ensuring all fasteners are torqued to specifications.

6. Reinstall Wheel and Final Checks

Tools Required: Lug wrench, torque wrench.
Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle off the jack stands.
3. Torque lug nuts to manufacturer specifications in a crisscross pattern.
