Solution

1. Preparation

Gather necessary tools and parts.
Safely elevate the vehicle using a jack and secure with jack stands.
Disconnect the battery to avoid any electrical issues.

2. Remove Wheel

Use a lug wrench to loosen and remove lug nuts from the wheel.
Take off the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench
Remove the caliper bolts using the socket set.
Carefully slide the caliper off the rotor; support it with a bungee cord to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the brake pad backing for uneven wear; replace if necessary.
Install new brake pads, ensuring they are properly aligned.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for grooves or scoring. If damaged, remove the rotor by unscrewing the retaining bolts.
Clean the hub surface before installing the new rotor.
Install the new rotor, ensuring it sits flush against the hub.

5. Reassemble Components

Reattach the brake caliper over the new pads and rotor.
Tighten caliper bolts to manufacturer specifications (consult repair manual for torque values).
Reinstall the wheel and hand-tighten lug nuts.

6. Final Checks

Lower the vehicle and fully tighten lug nuts in a star pattern to ensure even torque.
Reconnect the battery.
