Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, OBD-II scanner.
Steps:
1. Park the vehicle on a flat surface and engage the parking brake.
2. Disconnect the battery to prevent electrical mishaps.
3. Use the lug wrench to loosen the wheel bolts.
4. Raise the vehicle using a jack and secure with jack stands.

2. Remove Wheel

Steps:
1. Fully remove the wheel bolts and take off the wheel.
2. Inspect the wheel well for any debris or damage.

3. Inspect and Replace Brake Pads

Steps:
1. Remove the caliper bolts and detach the caliper from the rotor.
2. Support the caliper with a bungee cord or rope to prevent strain on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Compare new pads with old ones for size and fit.
5. Install new brake pads, ensuring they are properly seated in the caliper bracket.

4. Inspect and Replace Rotors

Steps:
1. Remove the caliper bracket bolts and take off the bracket.
2. Slide the rotor off the hub. If it’s stuck, gently tap with a rubber mallet.
3. Inspect the rotor for wear or damage; replace if necessary.
4. Install the new rotor, ensuring it is flush against the hub.

5. Reassemble Brake Components

Steps:
1. Reinstall the caliper bracket and tighten bolts to the manufacturer’s torque specification (usually 75-90 ft-lbs).
2. Reattach the caliper over the new pads and tighten caliper bolts (typically 25-30 ft-lbs).
3. Repeat for the other side if necessary.

6. Reinstall Wheel and Lower Vehicle

Steps:
1. Place the wheel back on the hub and hand-tighten bolts.
2. Lower the vehicle and use the torque wrench to tighten the wheel bolts to the manufacturer’s specifications (usually 100-120 ft-lbs).
