Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues.

2. Inspect and Replace Brake Components

Remove Wheel
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the wheel using a socket set.
Inspect Brake Pads
- Check the thickness of the brake pads; replace if worn below the manufacturer's specifications.
- Tools Required: Torque wrench, socket set.
Check Brake Rotors
- Measure rotor thickness with a micrometer; replace if below minimum thickness.
- Use a runout gauge to check for warping; replace if warped beyond specifications.
- Tools Required: Micrometer, runout gauge.
Reinstall or Replace Components
- If pads or rotors are replaced, reinstall new components in reverse order.
- Torque bolts to manufacturer specifications (usually around 80-100 ft-lbs for caliper bolts).

3. Inspect Suspension and Alignment

Check Suspension Components
- Inspect control arms, tie rods, and bushings for any visible wear or damage.
- Replace any damaged components.
Wheel Alignment
- After replacing suspension parts, perform a wheel alignment to ensure proper tracking.
- Tools Required: Alignment rack.
