Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Inspect Brake Pads and Rotors

Sub-steps:
1. Remove the wheel using a socket set.
2. Inspect brake pads for thickness; replace if below manufacturer specifications.
3. Measure rotor thickness with a micrometer; ensure it is within specifications.
4. Check for any scoring or warping on the rotor surface.
Tools Required:
- Socket set
- Micrometer

3. Replace Brake Pads and Rotors (if necessary)

Sub-steps:
1. Remove caliper bolts and carefully slide the caliper off the rotor.
2. Remove old brake pads from the caliper bracket.
3. Install new brake pads, ensuring they are seated correctly.
4. If rotors are warped or worn, remove the old rotor and install the new rotor; torque the bolts to manufacturer specifications.
Tools Required:
- Torque wrench
- Brake cleaner

4. Check Brake Calipers

Sub-steps:
1. Inspect calipers for proper movement on guide pins.
2. Clean and lubricate guide pins with brake grease if necessary.
3. Ensure calipers are securely mounted to the bracket.

5. Inspect Suspension Components

Sub-steps:
1. Check control arms, ball joints, and bushings for play or damage.
2. Replace any worn or damaged suspension components.
3. Reassemble all components and double-check tightness.
