Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, OBD-II scanner, torque wrench, brake cleaner, and safety glasses.
Ensure the vehicle is parked on a level surface and the ignition is off.
Disconnect the battery if necessary.

2. Inspect Brake Components

Sub-steps:
1. Remove the wheel using the lug wrench.
2. Inspect the brake pads for thickness; replace if they are worn below 3 mm.
3. Check the brake rotors for warping; use a dial indicator for accuracy.
4. If rotors are warped (more than 0.002 inches), either resurface or replace them.
5. Clean any dust or debris from the calipers and pads using brake cleaner.

3. Check Alignment and Suspension

Sub-steps:
1. Visually inspect suspension components (control arms, ball joints, tie rods) for any signs of wear or play.
2. If any components are damaged, replace as necessary.
3. Take the vehicle to a professional for a wheel alignment if it is out of specification.

4. Brake Caliper Inspection

Sub-steps:
1. Remove the caliper bolts and safely hang the caliper without stressing the brake line.
2. Inspect the caliper for proper movement; ensure it slides freely on its guide pins.
3. Lubricate the guide pins if necessary and replace any faulty calipers.
