Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent electrical issues during the repair.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts with a socket set and take off the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the mounting bolts with a socket set.
Carefully slide the caliper off the rotor without disconnecting brake lines.
Remove the old brake pads from the caliper bracket.
Check the caliper guide pins and lubricate them if necessary.
Install new brake pads, ensuring they are properly seated.

4. Inspect and Resurface/Replace Rotors

Check the rotors for any signs of scoring or warping; use a micrometer to measure thickness.
If rotors are within specification, they can be resurfaced; if not, replace them.
Reinstall the rotors if resurfaced or install new rotors by securing them with the appropriate bolts.

5. Reassemble Brake Components

Reattach the caliper over the new brake pads.
Tighten caliper mounting bolts to manufacturer specifications (typically 20-25 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and tighten the lug nuts in a crisscross pattern to the specified torque.
