Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, brake cleaner.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Raise the Vehicle

Use the jack to lift the vehicle and secure it with jack stands.
Remove the wheel using the lug wrench.

3. Inspect and Replace Brake Rotors

Sub-steps:
- Remove the caliper bolts and take off the brake caliper.
- Suspend the caliper using a bungee cord, avoiding strain on the brake line.
- Remove the rotor by unscrewing any retaining screws if applicable.
- Inspect the rotor for warping or scoring; measure thickness with a micrometer.
- If warped, replace the rotor with a new one, ensuring it meets OEM specifications.
- Reinstall the rotor.

4. Check and Replace Brake Pads

Sub-steps:
- Inspect the brake pads for wear; replace if the friction material is below 3mm.
- Clean the caliper bracket and apply anti-squeal lubricant to contact points.
- Install new brake pads into the caliper bracket.
- Reattach the caliper and tighten bolts to the manufacturer's torque specification.

5. Inspect and Repair Suspension Components

Sub-steps:
- Inspect control arms, bushings, and struts for wear or damage.
- Replace any worn or damaged components as necessary.
- Ensure all bolts are tightened to specification.

6. Wheel Alignment and Balancing

After repairs, take the vehicle to a professional service for alignment and balancing to ensure that the suspension is properly set.
