Solution

1. Preparation

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

2. Inspect Brake Pads

Sub-steps:
- Remove the wheel using a socket set.
- Inspect the brake pads for thickness and any signs of uneven wear.
- Replace brake pads if thickness is below the manufacturer’s specification (usually 3mm or less).
Tools Required: Socket set, torque wrench.

3. Check and Resurface/Replace Rotors

Sub-steps:
- Remove the calipers and hang them to avoid stress on the brake lines.
- Remove the brake rotor from the hub.
- Inspect the rotor for warping using a runout gauge; replace or resurface if beyond specifications.
- Reinstall the rotor after ensuring it is clean and free of rust.
Tools Required: Brake caliper tool, runout gauge, rotor resurfacing kit or replacement rotors.

4. Inspect and Service Brake Calipers

Sub-steps:
- Check caliper slides for smooth operation; lubricate or replace if sticky.
- Ensure the caliper piston moves freely; replace caliper if it is seized.
Tools Required: Brake caliper tool, lubricant.

5. Verify Wheel Alignment and Balance

Sub-steps:
- Check wheel balance using a balancing machine; adjust as necessary.
- Inspect alignment settings and adjust to manufacturer specifications.
Tools Required: Wheel alignment rack.

6. Reassemble and Test

Sub-steps:
- Reinstall all components in reverse order of disassembly.
- Tighten all bolts to manufacturer torque specifications.
- Reconnect the battery and perform a test drive to ensure the issue is resolved.
Tools Required: Torque wrench.
