Solution

1. Preparation

Gather all necessary tools and parts.
Safely elevate the vehicle using a hydraulic jack and support stands.
Disconnect the battery if necessary for electrical safety.

2. Remove Wheel Assembly

Remove the lug nuts using a socket set.
Take off the wheel to access the brake components.

3. Inspect and Replace Brake Rotors

Check for rotor warpage using a dial indicator.
If warping is present, remove the caliper by unscrewing the mounting bolts and hanging it with a bungee cord to avoid stress on the brake line.
Remove the rotor by unscrewing any retaining screws and sliding it off the hub.
Install new rotors, ensuring they are clean and properly seated.

4. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Compress the caliper piston using a brake caliper tool to allow for the new pads.
Install new brake pads, ensuring they are correctly oriented and seated.

5. Reassemble Components

Reattach the brake caliper and torque the bolts to manufacturer specifications (typically around 20-25 ft-lbs).
Reinstall the wheel and torque the lug nuts to the specified value (usually around 76-83 ft-lbs).
Reconnect the battery if it was disconnected.
