Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to avoid any electrical issues while working.

2. Remove Wheel

Tools Required: Socket set, lug wrench
Loosen the lug nuts on the wheel before lifting the vehicle.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Visually inspect the brake pads for thickness; if less than 1/8 inch, replace.
Sub-steps:
- Remove the caliper bolts using the appropriate socket.
- Carefully slide the caliper off the rotor without damaging the brake line.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads in the caliper bracket, ensuring they are seated correctly.
- Compress the caliper piston using a brake caliper tool to allow for new pads.

4. Inspect and Resurface/Replace Brake Rotors

Check rotors for grooves or warping using a micrometer.
If damaged, either resurface or replace them.
Sub-steps:
- Remove the caliper bracket if necessary.
- Unbolt the rotor from the hub.
- Install a new or resurfaced rotor, ensuring proper alignment.
- Reattach the caliper bracket and torque bolts to the manufacturer's specifications (typically 25-35 ft-lbs).

5. Reassemble and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands.
Torque the lug nuts to the manufacturer's specifications (typically 75-85 ft-lbs).
Reconnect the battery.
