Solution

1. Preparation

Gather all necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the vehicle is in “Park” mode and turn off the ignition.

2. Raise the Vehicle

Tools Required: Jack, jack stands, wheel chocks.
Sub-steps:
1. Loosen wheel lug nuts slightly while the vehicle is on the ground.
2. Use the jack to lift the vehicle and secure with jack stands.
3. Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench.
Sub-steps:
1. Remove the caliper bolts and carefully slide the caliper off the rotor.
2. Inspect brake pads for even wear; replace if worn beyond specifications.
3. If replacing, install new pads ensuring they are seated correctly.
4. Reinstall the caliper and torque bolts to manufacturer specifications.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Rotor puller (if needed), torque wrench.
Sub-steps:
1. Check rotor surface for warping or scoring; use a dial gauge to measure runout.
2. If rotors are warped, remove the old rotors.
3. Install new rotors, ensuring they are properly aligned and torqued.

5. Reassemble and Lower the Vehicle

Tools Required: Torque wrench.
Sub-steps:
1. Reattach the wheel and hand-tighten lug nuts.
2. Lower the vehicle and then torque the lug nuts to the specified value.
3. Recheck caliper operation and ensure all components are secure.
