Solution

1. Preparation

Gather tools and parts. Ensure the vehicle is parked on a flat surface.
Required tools: jack, jack stands, lug wrench, dial indicator, torque wrench, and basic socket set.
Safety Warning: Always wear appropriate personal protective equipment (PPE) and ensure the vehicle is securely lifted before working underneath.

2. Remove Wheels

Loosen lug nuts slightly while the vehicle is on the ground.
Using a jack, lift the vehicle and secure it with jack stands.
Completely remove the lug nuts and take off the wheels.

3. Inspect and Replace Brake Components

Inspect Rotors:
- Check for warping using a dial indicator. If warped beyond specifications (typically 0.003 inches), replace rotors.
Replace Brake Pads:
- Remove the caliper bolts using a socket set.
- Carefully slide the caliper off the rotor and support it (do not let it hang by the brake line).
- Remove old brake pads and install new ones, ensuring proper alignment.

4. Reassemble Components

Reattach the caliper, ensuring bolts are torqued to the manufacturer's specifications (usually around 20-25 ft-lbs).
Replace wheels and hand-tighten lug nuts.

5. Lower Vehicle and Torque Lug Nuts

Lower the vehicle off the jack stands.
Torque the lug nuts in a crisscross pattern to the specified torque (typically 76-80 ft-lbs).
