Disconnect the battery to avoid any electrical accidents.

Tools Required:

Jack and jack stands
Lug wrench
Socket set
Torque wrench
Brake cleaner

Carefully slide the caliper off the rotor and support it without stressing the brake line.
Remove the old brake pads from the caliper bracket.
Check the backing plates for damage; replace if necessary.
Install new brake pads, ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for grooves or warping.
If damaged, remove the rotor by unscrewing the retaining screws.
