Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues while working on the brakes.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench
Sub-steps:
1. Loosen the lug nuts slightly while the vehicle is on the ground.
2. Raise the vehicle with a jack and secure it on jack stands.
3. Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench
Sub-steps:
1. Remove the caliper by unscrewing the caliper bolts using the socket set.
2. Carefully slide the caliper off the rotor and suspend it (do not let it hang by the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper slides for dirt or corrosion; clean if necessary.
5. Install new brake pads, ensuring they are aligned correctly with the caliper.
6. Reattach the caliper and torque bolts to the manufacturer's specifications (usually around 20-30 lb-ft).

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Brake rotor removal tool (if rotors are stuck), socket set
Sub-steps:
1. If the rotors are scored or warped, remove them by unscrewing the retaining screws (if equipped).
2. Clean the hub surface with a wire brush to ensure a proper fit for the new rotors.
3. Install new rotors, ensuring they seat properly against the hub.
4. Reassemble the caliper and brake pads as previously instructed.

5. Reassemble and Lower Vehicle

Tools Required: Torque wrench
Sub-steps:
1. Reattach the wheel and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands and fully tighten the lug nuts in a star pattern to the specified torque (usually around 75-100 lb-ft).
