Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety glasses and gloves.

2. Inspect and Replace Brake Rotors

Tools Required: Jack and jack stands, lug wrench, torque wrench, socket set, brake cleaner, rotor puller (if necessary)
Sub-steps:
1. Loosen lug nuts on the front wheels while the vehicle is on the ground.
2. Lift the vehicle using a jack and securely place it on jack stands.
3. Remove the front wheels using the lug wrench.
4. Inspect the brake rotors for warping using a dial indicator; replace if warped beyond specifications.
5. If replacement is needed, remove the caliper bracket bolts and caliper. Hang the caliper using a wire to avoid strain on the brake line.
6. Remove the old rotor and clean the hub surface with brake cleaner.
7. Install the new rotor and reattach the caliper and caliper bracket with specified torque (generally 70-80 ft-lbs).

3. Inspect and Replace Brake Pads

Tools Required: Same as above
Sub-steps:
1. Remove the caliper as described in the previous step.
2. Take out the old brake pads from the caliper bracket.
3. Inspect the caliper slide pins for lubrication; apply high-temperature grease if needed.
4. Install new brake pads ensuring they fit securely in the caliper bracket.
5. Reinstall the caliper over the new pads and torque bolts to manufacturer specifications.

4. Inspect Suspension Components

Tools Required: Socket set, pry bar, torque wrench
Sub-steps:
1. Examine control arms, bushings, and struts for signs of wear or damage.
2. Use a pry bar to check for play in the suspension components.
3. Replace any worn or damaged parts with OEM or high-quality aftermarket parts.
