Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery (if working on electronic brake systems).

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brake pads are being replaced.
Secure with jack stands for safety.

3. Remove Wheel

Use a socket set to remove the lug nuts.
Take off the wheel to access the brake assembly.

4. Inspect Brake Pads

Check the thickness of the brake pads; replace if less than 3mm.
Inspect the condition of the rotors for scoring or warping.

5. Replace Brake Pads

Remove the caliper bolts with a socket set.
Carefully slide the caliper off the rotor.
Remove old brake pads from the caliper bracket.
Install new brake pads into the caliper bracket, ensuring correct orientation.
Reattach the caliper over the new pads and tighten bolts to manufacturer specifications (typically 25-30 Nm).

6. Reassemble and Lower Vehicle

Reinstall the wheel and hand tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specification (typically 100-120 Nm).
Reconnect the battery.
