Solution

1. Preparation

Gather necessary tools and parts for the brake pad replacement.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the negative battery terminal for safety.

2. Remove the Wheel

Use a jack to lift the vehicle and secure it on jack stands.
Remove the lug nuts using a socket wrench and take off the wheel.

3. Remove the Brake Caliper

Locate the caliper mounting bolts and remove them with a socket set.
Carefully slide the caliper off the brake rotor and support it with a bungee cord or rope (do not let it hang by the brake line).

4. Replace the Brake Pads

Remove the old brake pads from the caliper bracket.
Compare the thickness of the old pads with the new pads to ensure proper replacement.
Install the new brake pads, ensuring they are seated properly in the caliper bracket.

5. Reinstall the Brake Caliper

Compress the caliper piston using a brake caliper tool if necessary.
Position the caliper back over the new brake pads and align the mounting holes.
Reinstall and torque the caliper bolts to the manufacturer’s specifications (typically around 30-40 Nm).

6. Reinstall the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle and then use a torque wrench to tighten the lug nuts to the specified torque (usually around 100 Nm).

7. Final Checks

Reconnect the negative battery terminal.
Pump the brake pedal a few times to ensure the caliper piston seats properly against the new pads.
