Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Loosen the lug nuts slightly before lifting the vehicle.
Tools Required: Jack, jack stands, lug wrench, caliper, torque wrench.

2. Lift the Vehicle

Use the jack to lift the vehicle at the designated lift points.
Secure the vehicle with jack stands for safety.

3. Remove the Wheel

Fully remove the loosened lug nuts and take off the wheel.
Place the wheel aside in a safe location.

4. Remove Brake Caliper

Locate the caliper mounting bolts and remove them with the appropriate socket.
Carefully slide the caliper off the brake rotor and support it with a bungee cord or rope to avoid strain on the brake line.

5. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Inspect the caliper for wear and any issues before installing new pads.
Insert the new brake pads into the caliper bracket.
Use a brake caliper tool to compress the caliper piston if necessary, ensuring the new pads fit properly.

6. Reassemble

Reinstall the caliper over the new brake pads and secure it with the mounting bolts.
Torque the caliper bolts to the manufacturer’s specifications (typically around 25-30 Nm).
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Remove jack stands and lower the vehicle back to the ground.
Use the torque wrench to tighten the lug nuts to the proper specification (usually around 120 Nm).
