Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to prevent any electrical issues during repair.

2. Remove Wheel

Loosen lug nuts using a lug wrench.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brakes.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper by unbolting it from the mounting bracket.
2. Carefully slide the caliper off the brake pads. Do not stretch the brake line.
3. Remove the old brake pads from the caliper bracket and check for wear indicators.
4. Clean the caliper bracket and rotor using brake cleaner.
5. Install new brake pads, ensuring proper orientation and alignment.
6. Reattach the caliper over the new pads and tighten bolts to manufacturer specifications (typically around 20-25 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. If rotors are worn or warped, unbolt them from the hub.
2. Install new rotors, ensuring they are clean and free of debris.
3. Torque rotor bolts to manufacturer specifications (usually around 75-85 ft-lbs).

5. Reassemble and Lower Vehicle

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer's specifications (typically around 80-100 ft-lbs).
Reconnect the battery.
