Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Gather tools: jack, jack stands, lug wrench, caliper tool, torque wrench.

2. Remove Wheel

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

3. Inspect and Replace Brake Pads

Check the thickness of the brake pads; replace if below specification (usually 3mm).
Remove the caliper bolts with a socket set.
Slide the caliper off the rotor and secure it with a bungee cord (do not let it hang on the brake line).
Remove the old brake pads and replace them with new ones. Ensure they are properly seated.

4. Inspect and Replace Brake Rotors

Check the rotors for warping using a dial indicator or a straight edge.
If warped beyond acceptable limits, remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Install new rotors, ensuring they are clean and correctly mounted.

5. Reassemble Components

Reattach the brake caliper over the new pads and rotor.
Tighten caliper bolts to the manufacturer’s specified torque (usually around 30-40 lb-ft).
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Finalize

Lower the vehicle off the jack stands.
Torque the lug nuts to the manufacturer’s specifications (usually around 75-80 lb-ft).
Repeat the process for the other side if necessary.
