Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Raise and Secure the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes are being serviced.
Secure with jack stands to ensure safety while working underneath.

3. Remove the Wheel

Using a socket set, remove the lug nuts from the wheel.
Take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Sub-step 1: Remove the caliper by unbolting it from the bracket; use a torque wrench for proper reinstallation.
Sub-step 2: Carefully slide the old brake pads out of the caliper bracket.
Sub-step 3: Compare new brake pads with old ones to ensure correct size and fit.
Sub-step 4: Install the new brake pads into the caliper bracket.

5. Inspect and Replace Brake Rotors (if necessary)

Sub-step 1: If rotors are worn or damaged, unbolt and remove them from the hub.
Sub-step 2: Clean the hub surface with brake cleaner.
Sub-step 3: Install new rotors, ensuring they are seated properly.

6. Reassemble Components

Reattach the caliper over the new pads and torque the bolts to manufacturer specifications.
Reinstall the wheel and torque the lug nuts in a crisscross pattern to ensure even tightening.

7. Lower the Vehicle

Carefully remove the jack stands and lower the vehicle back to the ground.
