Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, torque wrench, safety glasses, and gloves.
Safety Warnings: Ensure the vehicle is on a flat surface and the parking brake is engaged. Always wear safety gloves and goggles.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Brake Pads: Remove the caliper bolts and slide the caliper off the rotor. Inspect the brake pads for thickness; replace if they are worn down to 3mm or less.
Brake Rotors: Check the surface of the rotors for scoring or pitting. If damaged, machine or replace the rotors as necessary.
Calipers: Ensure calipers are functioning properly with no leaks. Replace if they are sticking or damaged.

4. Replace Brake Pads and Rotors (if necessary)

If replacing pads, remove the old pads and install new ones, ensuring they are properly seated.
If replacing rotors, remove the old rotors and install new ones, ensuring they are torqued to manufacturer specifications (typically around 80-100 ft-lbs).

5. Reassemble Components

Reattach the brake caliper over the new pads or rotors, tightening the caliper bolts to the manufacturer's specifications.
Replace the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Torque Lug Nuts

Carefully lower the vehicle back to the ground.
Use the torque wrench to tighten the lug nuts to the specified torque (usually around 100-150 ft-lbs, depending on model).

7. Test Brakes

Pump the brakes a few times to seat the pads against the rotors before driving.
