Solution

1. Preparation

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

2. Raise the Vehicle

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

3. Inspect and Replace Brake Pads

Inspect Brake Pads: Check the thickness of the pads; replace if less than 3mm.
Remove Brake Caliper:
- Use a socket wrench to remove caliper mounting bolts.
- Secure the caliper using a bungee cord or strap to avoid stressing the brake line.
Replace Pads:
- Remove old pads and install new pads, ensuring they are properly aligned.

4. Inspect and Resurface or Replace Rotors

Remove Brake Rotor:
- If necessary, remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Check for Warpage:
- Use a run-out gauge to check for excessive run-out; if warped beyond manufacturer specifications, resurface or replace rotors.
Resurface (if applicable):
- Follow the machine shop's guidelines for resurfacing.
Install New or Resurfaced Rotors:
- Slide the rotor back onto the hub and secure with retaining screws.

5. Reassemble Components

Reinstall the brake caliper and tighten the mounting bolts to the manufacturer's torque specifications (typically around 25-30 lb-ft).
Reinstall the wheel and lug nuts, tightening to the manufacturer's specifications (usually 100-140 lb-ft).

6. Lower the Vehicle

Remove the jack stands and lower the vehicle back to the ground.
