Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, brake cleaner, wire brush, caliper tool, brake pad spreader.
Safety Warnings: Always wear safety goggles and gloves. Ensure the vehicle is on a flat surface and securely supported with jack stands.

2. Remove Wheels

Loosen the lug nuts with a lug wrench.
Elevate the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and detach the wheels.

3. Inspect and Replace Brake Components

A. Inspect Brake Pads

Remove the brake caliper using a socket set and inspect the brake pads.
If the pads are worn down to less than 3mm, replace them.

B. Inspect Brake Rotors

Check rotors for any signs of scoring or uneven surfaces. If damaged, replace.
If they are within specification, clean the surface with brake cleaner and a wire brush.

C. Replace Brake Pads

Install new brake pads if necessary. Ensure they are positioned correctly in the caliper bracket.
Apply a thin layer of anti-squeal grease to the back of the pads.

4. Reassemble Brake Components

Reattach the brake caliper over the new pads and torque bolts to manufacturer specifications (typically around 25-35 ft-lbs).
Reinstall the wheels and hand-tighten the lug nuts.

5. Lower Vehicle and Torque Wheels

Carefully lower the vehicle from the jack stands.
Fully torque the lug nuts in a crisscross pattern to the manufacturer’s specification (typically around 80-100 ft-lbs).
