Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical issues.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench
Loosen lug nuts slightly before lifting the vehicle.
Use the jack to raise the vehicle and secure with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect the brake pads for thickness and wear.
If worn, remove the caliper by unbolting it from the bracket.
Carefully slide out the old brake pads from the caliper bracket.
Insert new brake pads into the bracket.
Reinstall the caliper over the new pads and torque bolts to manufacturer specifications (typically 20-30 ft-lbs).

4. Inspect and Replace Rotors

If rotors are scored or warped, remove them by unbolting from the hub.
Clean the mounting surface on the hub with brake cleaner.
Install new rotors and torque the bolts to manufacturer specifications (typically 75-90 ft-lbs).

5. Reassemble and Test

Reinstall the wheel and hand-tighten lug nuts.
Lower the vehicle and torque lug nuts to specifications (typically 100-130 ft-lbs).
Reconnect the battery and start the vehicle.
Test the brakes gently to ensure proper function before driving.
