Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety gloves and glasses for protection.

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. Jack up 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, brake pad spreader
Sub-steps:
1. Inspect the brake pads for thickness; replace if less than 3mm.
2. Remove the caliper bolts using a socket set.
3. Carefully lift the caliper off the rotor; support it with a wire to avoid stress on the brake line.
4. Remove old brake pads from the caliper bracket.
5. If needed, use a brake pad spreader to compress the caliper piston.
6. Install new brake pads into the caliper bracket.
7. Reattach the caliper and tighten the bolts to the manufacturer's torque specification.

4. Inspect and Replace Brake Rotors (if necessary)

Tools Required: Rotor puller (if needed), torque wrench
Sub-steps:
1. Check the rotor surface for grooves or warping; replace if damaged.
2. Remove the rotor by taking off the retaining screws (if equipped).
3. Install the new rotor and secure it using the retaining screws.
4. Ensure the rotor surface is clean and free of debris.

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 and then tighten the lug nuts in a crisscross pattern to the specified torque.
3. Pump the brake pedal to ensure proper brake pad and caliper contact.
4. Test drive the vehicle to ensure noise is eliminated and braking is effective.
