Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and secure with wheel chocks.
Disconnect the battery for safety.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the wheel using a socket set.
2. Remove the caliper by loosening caliper bolts, and support it with a bungee cord to avoid stress on the brake line.
3. Remove the brake pads and inspect them for wear.
4. Use a caliper gauge to measure rotor thickness and check for warping using a dial indicator.
5. If rotors are warped or below minimum thickness, replace with new rotors.
Tools Required: Socket set, caliper gauge, dial indicator.

3. Replace Brake Pads

Sub-steps:
1. If needed, clean the caliper bracket and apply brake grease to contact points.
2. Install new brake pads into the caliper bracket.
3. Compress the caliper piston using a brake tool to allow for new pads.
4. Reinstall the caliper over new pads and torque bolts to manufacturer specifications.
Tools Required: Brake tool, torque wrench.

4. Check Wheel Bearings

Sub-steps:
1. Raise the vehicle and remove the affected wheel.
2. Grasp the wheel at the 12 and 6 o'clock positions and check for play.
3. If play is detected, disassemble the hub assembly and replace wheel bearings as necessary.
Tools Required: Socket set, bearing puller.

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and lower the vehicle.
2. Reconnect the battery.
3. Pump the brake pedal to seat the pads.
4. Test drive the vehicle to ensure vibrations are resolved.
