Solution

1. Preparation

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

2. Inspect and Replace Brake Pads

Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake assembly.
Inspect the brake pads for thickness; replace if worn down to less than 3mm.
Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor.
Replace the old brake pads with new ones, ensuring they are properly seated.
Reinstall the caliper and torque the bolts to manufacturer specifications (typically 20-30 ft-lbs).

3. Check and Resurface or Replace Brake Rotors

Use a micrometer to measure rotor thickness; replace if below minimum specifications.
If rotors are within specifications but warped, consider resurfacing them using a brake lathe.
If replacing, remove the rotor retaining screws and pull off the old rotor.
Install the new rotor, ensuring it is properly aligned, and torque any retaining screws to specification.

4. Inspect and Replace Wheel Bearings

With the wheel removed, check for any play in the wheel hub by wiggling it.
If play is detected, remove the wheel hub assembly.
Replace the wheel bearing using a bearing press if necessary, or consult manufacturer specifications for replacement procedures.

5. Tire Inspection and Balancing

Inspect tires for uneven wear or damage; replace if necessary.
Ensure tires are properly inflated to manufacturer specifications.
Have the tires balanced at a professional shop if vibration persists.
