Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, basic hand tools.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery if necessary for safety.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a lug wrench.
2. Remove the brake caliper by unbolting it from the bracket.
3. Slide out the old brake pads.
4. Inspect the brake pad thickness; replace if less than 3mm.
5. Install new brake pads, ensuring they are seated properly.
6. Reattach the brake caliper and torque bolts to specifications (usually around 25-35 lb-ft).

3. Check and Replace Brake Rotors

Sub-steps:
1. Remove the brake caliper and pads as described above.
2. Remove the rotor by unbolting it from the hub assembly.
3. Inspect the rotor for warping (use a dial indicator) or scoring.
4. Replace rotors if they are warped beyond the manufacturer's specifications (typically more than 0.002 inches).
5. Install new rotors, ensuring they are clean and free of oil or debris.
6. Reinstall brake pads and caliper.

4. Inspect Suspension and Wheel Components

Sub-steps:
1. Check the condition of the upper and lower control arms, bushings, and ball joints.
2. Inspect the wheel bearings for any play or roughness; replace if necessary.
3. Ensure the tie rod ends are secure and show no signs of wear.
4. Reassemble any components that were inspected or replaced.
