Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the car is on a flat surface and secure it with wheel chocks.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts on the wheel using a lug wrench.
2. Jack up the vehicle using a hydraulic jack.
3. Secure the vehicle on jack stands.
4. Remove the lug nuts completely and take off the wheel.
Tools Required: Lug wrench, hydraulic jack, jack stands.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket wrench and carefully slide the caliper off the rotor.
2. Remove the old brake pads from the caliper bracket.
3. Inspect the caliper for any signs of damage or sticking.
4. Install new brake pads, ensuring they are correctly positioned in the caliper bracket.
5. Reinstall the caliper over the new pads and tighten caliper bolts to manufacturer specifications (typically around 20-30 ft-lbs).
Tools Required: Socket set, torque wrench.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. If the rotors are scored or warped, remove them from the hub by removing any retaining screws.
2. Clean the hub surface to ensure proper contact with the new rotor.
3. Install the new rotor on the hub and secure it with retaining screws.
Tools Required: Torque wrench, rotor puller (if needed).

5. Final Assembly

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle off the jack stands using the hydraulic jack.
3. Tighten lug nuts to the manufacturer’s specifications (typically around 76-80 ft-lbs).
4. Reconnect the negative battery terminal.
Tools Required: Hydraulic jack, lug wrench, torque wrench.
