Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Remove Front Wheel

Sub-steps:
- Loosen the lug nuts using a lug wrench.
- Raise the vehicle with a jack and secure it on jack stands.
- Fully remove the lug nuts and take off the front wheel.
Tools Required: Lug wrench, floor jack, jack stands.

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper bolts with a socket set and carefully slide the caliper off the rotor.
- Remove the old brake pads from the caliper bracket.
- Compare the old pads with new pads (ensure correct sizing).
- Install new brake pads into the caliper bracket.
Tools Required: Socket set, brake pad spreader.

4. Check and Resurface/Replace Brake Rotors

Sub-steps:
- Remove the rotor by taking off the retaining screws (if applicable).
- Measure rotor thickness using a micrometer; if below minimum specifications, replace the rotor.
- If rotors are within spec but warped, have them resurfaced by a professional.
- Install the rotor back onto the hub and secure it with retaining screws.
Tools Required: Micrometer, torque wrench.

5. Reinstall Caliper and Wheel

Sub-steps:
- Reinstall the caliper over the new pads and torque the caliper bolts to manufacturer specifications.
- Place the wheel back onto the hub and hand-tighten the lug nuts.
- Lower the vehicle and torque the lug nuts to the manufacturer specifications.
