Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety glasses and gloves.

2. Lift Vehicle

Use a jack to lift the front end of the vehicle.
Secure with jack stands to ensure stability.

3. Inspect and Replace Brake Rotors

Tools Required: Socket set, torque wrench, brake rotor removal tool.
Remove the wheel to access the brake components.
Unbolt the caliper and hang it securely (do not let it dangle).
Remove the brake pads from the caliper bracket.
Remove the rotor bolts and take off the rotor.
Inspect the rotor for warping using a dial indicator; replace if warped beyond manufacturer specifications.
Install the new rotor and torque bolts to manufacturer specifications.

4. Inspect and Replace Brake Pads

Check the brake pads for wear; if they are below the recommended thickness, replace them.
Clean the caliper bracket with brake cleaner before installing new pads.
Apply brake grease to the backing of new pads to prevent squeaking.
Reassemble the caliper and wheel, ensuring all bolts are torqued properly.

5. Inspect Suspension Components

Check for any play in the control arms and ball joints by shaking them.
Replace any worn or damaged components as necessary.

6. Rebalance Wheels

If the tires are found to be unbalanced during diagnostics, take the vehicle to a tire shop for balancing.
Ensure all tires are properly inflated.
