Solution

1. Preparation

Gather tools and materials.
- Tools Required: Jack, jack stands, lug wrench, caliper gauge or ruler, brake cleaner, gloves, safety glasses.
- Safety Warnings: Ensure the vehicle is on a flat surface and secured before lifting.

2. Lift the Vehicle

Using a jack, lift the front or rear of the vehicle as needed.
Secure the vehicle with jack stands for safety.

3. Remove Wheel

Use the lug wrench to loosen and remove the lug nuts from the wheel.
Take off the wheel to expose the brake assembly.

4. Inspect Brake Pads

Use a caliper or ruler to measure the thickness of the brake pads.
- Minimum thickness for replacement is typically around 3mm.
If the pads are worn below this thickness, they need to be replaced.

5. Replace Brake Pads (if necessary)

Remove the caliper bolts using a socket set.
Carefully slide the caliper off the rotor.
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are positioned correctly.
Reattach the caliper over the new pads and tighten the caliper bolts to the manufacturer’s torque specifications (typically around 25-35 ft-lbs).

6. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a criss-cross pattern.
