2. Jack up the vehicle and secure it with jack stands.
3. Remove the lug nuts and take off the wheel.
Tools Required: Jack, jack stands, lug wrench.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Slide the caliper off the rotor and secure it (do not let it dangle from the brake line).
3. Remove the old brake pads and inspect for wear; replace if less than 1/8 inch thick.
4. Apply brake grease to the backing of the new pads.
5. Install the new brake pads in the caliper bracket.
Tools Required: Socket set, brake grease.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:

2. If damaged, remove the rotor by unbolting it from the hub.
3. Install the new rotor, ensuring it is seated properly.
4. Torque the rotor bolts to manufacturer specifications.
Tools Required: Torque wrench.

5. Reassemble Brake Components

Sub-steps:
1. Reinstall the caliper over the new pads.
2. Tighten the caliper bolts to manufacturer specifications.
3. Reattach the wheel and hand-tighten the lug nuts.
Tools Required: Torque wrench.

6. Lower Vehicle and Final Checks

Sub-steps:
1. Lower the vehicle off the jack stands.
2. Torque the lug nuts to manufacturer specifications in a crisscross pattern.
3. Pump the brake pedal to seat the pads against the rotors.
