Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a flat surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the front wheels using a socket set.
2. Inspect the brake rotors for warping with a dial indicator; if warped beyond specifications (typically 0.002 inches), proceed to replace.
3. Remove the caliper bracket bolts and carefully detach the caliper from the rotor. Hang it securely using a wire to avoid straining the brake line.
4. Remove the rotor from the hub. Clean the hub surface to ensure proper seating of the new rotor.
5. Install the new rotor, ensuring it sits flat against the hub.
6. Reattach the caliper and tighten the caliper bracket bolts to the manufacturer’s torque specifications (usually around 25-35 ft-lbs).

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the old brake pads from the caliper bracket.
2. Inspect the caliper piston for proper operation; retract it if necessary using a brake caliper tool.
3. Install new brake pads, ensuring they fit snugly in the caliper bracket.
4. Reinstall the caliper over the new pads and ensure it is securely fastened.

4. Check Suspension Components

Sub-steps:
1. Inspect control arms, ball joints, and bushings for any signs of wear or damage.
2. Replace any damaged components with OEM or equivalent parts.
3. Tighten all suspension bolts to the specified torque values.

5. Wheel Balance and Tire Inspection

Sub-steps:
1. Remove the wheels and check for any visible damage or uneven wear.
2. Have the wheels balanced at a tire shop if necessary.
3. Replace tires if they are worn or damaged.
