Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a lug wrench.
2. Remove the caliper by unbolting it from the bracket (typically 14mm socket).
3. Slide out the old brake pads from the caliper bracket.
4. Inspect the caliper for any damage or leaking fluid.
5. Install new brake pads, ensuring they seat properly in the bracket.
6. Reattach the caliper and torque bolts to manufacturer's specifications (usually around 20-25 ft-lbs).

3. Check and Resurface/Replace Rotors

Sub-steps:
1. Measure rotor thickness with a micrometer; ensure it meets minimum specifications.
2. If warping is detected, either resurface the rotors (if within limits) or replace them.
3. Clean the rotor surface with brake cleaner before installation.
4. Install the rotor and torque the retaining bolts as per specifications.

4. Inspect and Replace Suspension Components (if needed)

Sub-steps:
1. Visually inspect control arms, bushings, and struts for signs of wear or damage.
2. Replace any worn components using appropriate tools (often 12mm or 14mm sockets).
3. Torque new components to manufacturer's specifications.

5. Reinstall Wheel and Test Drive

Sub-steps:
1. Reinstall the wheel and hand-tighten lug nuts.
2. Lower the vehicle and torque lug nuts to manufacturer's specifications (usually around 80-100 ft-lbs).
3. Reconnect the negative battery terminal.
4. Conduct a test drive to ensure the issue is resolved.
