Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the 12V battery for safety.

2. Inspect Brake Components

Brake Pad Inspection:
- Remove the wheel using a socket set.
- Inspect brake pads for thickness; replace if less than 3mm.
Rotor Inspection:
- Clean the rotor surface with brake cleaner.
- Measure rotor thickness with a micrometer; replace if below minimum specifications.
- Check for warping using a dial indicator; if warped, replace rotors.

3. Replace Brake Pads and Rotors (if necessary)

Brake Pad Replacement:
- Remove caliper bolts using a torque wrench (typically 25-35 ft-lbs).
- Slide out old pads and install new ones, ensuring proper alignment.
Rotor Replacement:
- Remove the caliper and bracket to access the rotor.
- Remove the old rotor and install the new one, securing it with appropriate torque specifications.

4. Inspect and Replace Suspension Components (if necessary)

Suspension Inspection:
- Visually inspect control arms, bushings, and struts for wear.
- Test for play in ball joints and bushings.
Replacement:
- If any components are damaged, remove and replace them using appropriate tools.
- Torque new components to manufacturer specifications.

5. Reassembly and Reinstallation

Reinstall the wheel and lower the vehicle.
Reconnect the battery.
Ensure all components are secured and properly torqued.
