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 and Replace Brake Pads

Tools Required: Jack and jack stands, socket set, brake pad spreader.
Remove the wheel using a socket set.
Inspect brake pads for uneven wear; replace if necessary:
- Remove caliper bolts and slide the caliper off.
- Remove old brake pads and install new pads, ensuring they are the correct thickness.
- Reinstall the caliper and torque bolts to manufacturer specifications (typically around 25-30 Nm).

3. Check and Replace Brake Rotors

Tools Required: Dial indicator, socket set, rotor puller (if necessary).
Use a dial indicator to measure rotor runout:
- If the rotor is warped (more than 0.05 mm), replace it.
- To replace, remove caliper and caliper bracket.
- Remove old rotor and install the new rotor, ensuring it is seated properly.
- Reinstall caliper bracket and caliper, torquing to manufacturer specifications.

4. Inspect Suspension Components

Tools Required: Visual inspection tools, torque wrench.
Check tie rods, control arms, and bushings for signs of wear or damage.
Replace any damaged components:
- Remove the affected part and install the new component, following specific torque values provided in the service manual.

5. Final Checks

Reinstall the wheel and torque lug nuts to manufacturer specifications (typically 90-120 Nm).
Reconnect the battery and perform a test drive to ensure the issue is resolved.
