Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Remove Wheel

Sub-steps:
- Loosen the lug nuts using a lug wrench.
- Lift the vehicle with a jack and secure it on jack stands.
- Remove the lug nuts and take off the wheel.

3. Remove Brake Caliper

Tools Required: Socket set, torque wrench
Sub-steps:
- Locate the caliper mounting bolts and remove them with the socket set.
- Carefully slide the caliper off the brake rotor without stretching the brake line.
- Support the caliper using a bungee cord or rope to avoid straining the brake line.

4. Replace Brake Pads

Sub-steps:
- Remove the old brake pads from the caliper bracket.
- Clean the caliper bracket and apply brake grease to the backing of the new pads.
- Install the new brake pads in the caliper bracket ensuring proper alignment.

5. Reassemble Components

Sub-steps:
- Compress the brake caliper piston using a brake caliper tool to make space for the thicker new pads.
- Reinstall the brake caliper over the new pads and secure it with the mounting bolts, torquing them to the manufacturer’s specifications.
- Reattach the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Check

Sub-steps:
- Lower the vehicle from the jack stands.
- Tighten the lug nuts to the proper torque specification using the torque wrench.
- Pump the brake pedal several times to seat the brake pads properly.
