Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, brake pad thickness gauge, micrometer.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves for protection.

2. Lift the Vehicle

Loosen the lug nuts on the front or rear wheel (depending on which pads are being replaced).
Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel completely.

3. Remove Brake Caliper

Locate the brake caliper mounting bolts and remove them using a socket wrench.
Carefully slide the caliper off the brake rotor. Do not let it hang by the brake line; support it with a bungee cord or similar.

4. Inspect and Remove Old Brake Pads

Remove the old brake pads from the caliper bracket. Note the orientation for installation of the new pads.
Inspect the caliper and rotor for any signs of damage or excessive wear.

5. Install New Brake Pads

Place the new brake pads into the caliper bracket in the same orientation as the old pads.
If necessary, compress the caliper piston using a caliper tool to make space for the new pads.

6. Reassemble the Brake Assembly

Position the brake caliper back over the new pads and rotor.
Reinstall the caliper mounting bolts and torque them to manufacturer's specifications (typically around 25-30 Nm, but verify for your specific model).

7. Reattach Wheel and Lower Vehicle

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and then use a torque wrench to tighten the lug nuts to the manufacturer's specifications (typically 100-120 Nm).
