Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, brake cleaner, torque wrench.
Raise the vehicle securely on jack stands after loosening the lug nuts. Ensure the vehicle is on a flat surface and the parking brake is engaged.

2. Remove Wheel

Sub-steps:
1. Remove the lug nuts completely and take off the wheel.
2. Inspect the wheel for any visible damage or debris.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the brake caliper by loosening the caliper bolts using a socket set.
2. Carefully lift the caliper off the brake rotor; do not let it hang by the brake line.
3. Remove the old brake pads from the caliper bracket; check for wear indicators.
4. Clean the caliper bracket and rotor surface with brake cleaner.
5. Install new brake pads into the caliper bracket, ensuring they are properly seated.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotor for grooves or warping; measure thickness with a micrometer.
2. If the rotor is damaged, remove it by loosening the retaining screws (if applicable) and sliding it off the hub.
3. Install the new rotor, ensuring it is properly aligned and secured.

5. Reassemble Components

Sub-steps:
1. Reposition the brake caliper over the new brake pads.
2. Tighten the caliper bolts to the manufacturer's specifications (consult service manual for torque values).
3. Reinstall the wheel and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle and torque the lug nuts to the specified value.
Pump the brake pedal several times to seat the pads against the rotor.
