Diagnostic Steps

1
Inspect brake pads for wear and ensure they are within specifications.
2
Examine brake rotors for warping or uneven surfaces.
3
Check for any loose or damaged brake components (calipers, hardware).
4
Verify that wheel lug nuts are properly torqued.
5

Solution

1. Preparation

Gather tools: jack and jack stands, lug wrench, torque wrench, caliper tool, brake cleaner, and safety glasses.
Ensure the vehicle is on a level surface and the engine is off.
Wear safety gloves and glasses.

2. Raise the Vehicle

Loosen the lug nuts on the front wheels slightly while the vehicle is on the ground.
Use the jack to lift the front of the vehicle and secure it with jack stands.
Remove the front wheels using the lug wrench.

3. Inspect Brake Components

Brake Pads:
- Remove the caliper bolts using the appropriate socket.
- Lift the caliper off the rotor and support it with a bungee cord (do not let it dangle).
- Check the brake pads for thickness; replace if less than 3mm.
Brake Rotors:
- Inspect the rotor surface for scoring or warping using a straight edge.
- If warped (more than 0.002 inches), resurface or replace the rotors.
Caliper and Hardware:
- Inspect caliper pins for lubrication and smooth operation.
- Replace any corroded or damaged components.

4. Reassemble Components

Reinstall the caliper over the new or resurfaced rotor.
Torque the caliper bolts to the manufacturer's specifications (typically around 20-30 ft-lbs).
Reattach the wheel and hand-tighten the lug nuts.

5. Lower the Vehicle

Remove the jack stands and lower the vehicle back to the ground.
Torque the lug nuts to the manufacturer’s specifications (usually around 75-85 ft-lbs).
