Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety goggles and gloves.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench.
Sub-steps:
1. Loosen the lug nuts slightly while the wheel is still on the ground.
2. Use the jack to lift the vehicle and secure it with 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 bolts using a socket wrench.
2. Carefully slide the caliper off the brake rotor and suspend it with a wire (do not let it hang by the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper guide pins for movement and lubricate if necessary.
5. Install new brake pads, ensuring they are seated correctly.
6. Reattach the caliper and torque the bolts to the manufacturer’s specifications (typically around 25-35 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Rotor puller (if stuck), torque wrench.
Sub-steps:
1. If rotors are warped or damaged, remove them by unscrewing the caliper bracket.
2. Install new rotors, ensuring they sit flush against the hub.
3. Torque the caliper bracket bolts to manufacturer specifications (usually around 70-80 ft-lbs).

5. Reassemble and Test

Tools Required: Lug wrench, jack.
Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle from the jack stands and tighten the lug nuts in a star pattern to the manufacturer’s torque specification (usually around 76-83 ft-lbs).
3. Pump the brake pedal to ensure pads are seated properly before test driving.
