Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, lug wrench, socket set, brake cleaner, dial indicator, torque wrench.
Park the vehicle on a level surface and engage the parking brake.
Place wheel chocks behind the rear wheels.

2. Lift the Vehicle

Use a jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using a lug wrench.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts with a socket set.
- Carefully slide the caliper off the rotor and suspend it without stress on the brake line.
- Inspect the brake pads for uneven wear; replace if necessary.
Brake Rotors:
- Use a dial indicator to measure rotor runout. If the measurement exceeds manufacturer specifications (typically .002-.005 inches), the rotor may need resurfacing or replacement.
- Clean the rotor surface using brake cleaner before reinstalling.

4. Check Calipers and Suspension

Inspect the caliper for smooth operation; ensure the piston moves freely.
Check the caliper slides for cleanliness and lubrication; replace if binding.
Inspect suspension components for wear or damage; replace any faulty parts, focusing on bushings and joints.

5. Reassemble Components

Reinstall the brake caliper and torque the bolts to the manufacturer’s specifications (usually around 25-35 lb-ft).
Reinstall the brake pads if replaced.
Reattach the wheel and torque the lug nuts in a star pattern to the specified torque (typically 100-150 lb-ft).

6. Lower the Vehicle

Remove the jack stands and lower the vehicle using the jack.
Conduct a final inspection of all components to ensure everything is secure.
