Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, caliper gauge, brake cleaner, torque wrench.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheels using a lug wrench.

2. Inspect Brake Components

Check the brake pads for thickness:
- Use a caliper gauge to measure the thickness of each brake pad.
- Note any pads that are significantly thinner than others.
Examine the brake rotors:
- Look for grooves, scoring, or uneven surfaces.
Inspect calipers:
- Ensure calipers move freely and are not seized. If they are not, clean and lubricate the caliper slides.

3. Replace Brake Pads (if necessary)

Tools Required: Brake pad replacement kit, brake grease.
Remove caliper bolts and carefully take off the caliper.
Remove old brake pads from the caliper bracket.
Install new brake pads, ensuring they are properly aligned.
Apply brake grease to the backing of the pads to prevent noise.

4. Address Underlying Issues

If calipers were found to be sticking, replace them with new calipers.
If the alignment is off, take the vehicle to a professional for alignment adjustments.
Ensure brake fluid is topped off and in good condition; replace if necessary.

5. Reassemble

Reinstall the caliper over the new pads and torque the bolts to the manufacturer's specifications.
Reattach the wheels and lower the vehicle.
Torque the lug nuts to the specified value.
