Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.

2. Lift the Vehicle

Sub-steps:
- Use a jack to raise the vehicle.
- Secure with jack stands for safety.
Tools Required:
- Floor jack
- Jack stands

3. Remove the Wheel

Sub-steps:
- Loosen lug nuts with a socket wrench.
- Remove the lug nuts and take off the wheel.
Tools Required:
- Lug wrench or socket set

4. Inspect and Replace Brake Pads

Sub-steps:
- Locate the brake caliper and remove the caliper bolts using a socket wrench.
- Slide the caliper off the rotor and support it using a bungee cord or similar.
- Remove the old brake pads from the caliper bracket.
- Compare the thickness of the old pads to the new ones; replace if they are below the minimum thickness (usually around 3mm).
- Apply brake grease to the back of the new pads to prevent squeaking.
- Install the new brake pads in the caliper bracket.
- Reinstall the caliper over the new pads and secure it with bolts; torque to the manufacturer's specification (usually around 25-30 Nm).
Tools Required:
- Socket wrench
- Torque wrench
- Brake grease
Safety Warnings:
- Ensure the brake fluid reservoir cap is opened to prevent pressure issues when compressing the caliper piston.

5. Reinstall the Wheel

Sub-steps:
- Place the wheel back onto the hub and hand-tighten the lug nuts.
- Lower the vehicle slightly to put weight on the wheel, then torque the lug nuts to the manufacturer’s specification (usually around 120 Nm).
Tools Required:
- Torque wrench

6. Lower the Vehicle and Test Brakes

Sub-steps:
- Carefully lower the vehicle off the jack stands.
- Press the brake pedal several times to seat the new brake pads.
Tools Required:
- Floor jack
