Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Raise Vehicle

Use a jack to lift the front or rear of the vehicle, depending on where the issue is suspected.
Secure with jack stands for safety.

3. Inspect and Replace Brake Rotors

Inspect Rotors:
- Remove the wheel using a socket set.
- Check rotors for warping using a dial indicator or by visually inspecting for grooves or uneven surfaces.
Replace Rotors (if necessary):
- Remove the caliper bracket bolts and slide off the caliper.
- Remove the old rotor.
- Install the new rotor, ensuring it is properly seated.
- Reattach the caliper bracket and torque bolts to manufacturer specifications.

4. Inspect and Replace Brake Pads

Inspect Pads:
- Check the thickness of the brake pads during rotor inspection.
Replace Pads (if necessary):
- Remove the old brake pads from the caliper bracket.
- Install new pads, ensuring they are aligned properly.
- Reinstall the caliper over the new pads and torque bolts to specifications.

5. Check Suspension Components

Inspect Components:
- Visually examine control arms, bushings, and tie rod ends for signs of wear or damage.
Replace Worn Components:
- If any component is found to be damaged, follow the manufacturer’s specifications for removal and installation.
