Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and glasses.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the wheel using a socket set.
2. Locate the brake caliper and remove the caliper bolts.
3. Slide the caliper off the rotor and support it with a bungee cord.
4. Remove old brake pads from the caliper bracket.
5. Install new brake pads, ensuring they are properly seated.
6. Reassemble the caliper and torque the bolts to manufacturer specifications (typically around 30-40 Nm).

3. Check and Replace Brake Rotors (if necessary)
