Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to avoid any electrical issues during the repair.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts using a lug wrench.
2. Lift the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor and suspend it without stressing the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Compare the new pads with the old ones to ensure correct fitment.
5. Apply brake grease to the back of the new pads to minimize noise.
6. Install the new brake pads into the caliper bracket.

4. Check and Replace Caliper (if necessary)

Sub-steps:
1. If calipers are found to be sticking, remove the caliper from the bracket.
2. Replace any damaged components, or install a new caliper if required.
3. Ensure to bleed the brake system if the caliper is replaced.

5. Reassemble

Sub-steps:
1. Reinstall the caliper over the new brake pads.
2. Torque the caliper bolts to the manufacturer’s specifications (typically around 20-25 ft-lbs).
3. Reinstall the wheel and hand-tighten the lug nuts.
4. Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically around 80-90 ft-lbs).

6. Final Checks
