Solution

1. Preparation

Gather tools and parts needed for the replacement.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove Wheel

Loosen the lug nuts using a socket wrench while the vehicle is still on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel to access the brake components.

3. Remove Old Brake Pads

Locate the brake caliper and remove the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor and support it using a bungee cord or a piece of wire to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.

4. Install New Brake Pads

Apply brake grease to the back of the new brake pads to prevent squeaking.
Insert the new brake pads into the caliper bracket in the same position as the old pads.
If necessary, compress the caliper piston using a brake caliper tool to accommodate the new pads.

5. Reassemble and Test

Slide the caliper back over the new brake pads and align it with the rotor.
Reinstall the caliper bolts and torque them to the manufacturer's specifications (typically around 30-40 Nm).
Reinstall the wheel, hand-tighten the lug nuts, and lower the vehicle back to the ground.
Tighten the lug nuts to the recommended torque specification (usually around 120 Nm).
