Solution

1. Preparation

Gather tools: jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety goggles.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on the vehicle.

2. Raise the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes are making noise.
Place jack stands under the vehicle for added safety.

3. Remove the Wheel

Use a lug wrench to loosen and remove the lug nuts.
Carefully take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Inspect Brake Pads: Check the thickness of the pads. If they are less than 3mm, replace them.
Replace Brake Pads:
1. Remove the caliper bolts using a socket set.
2. Slide the caliper off the rotor.
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads into the bracket.
5. Reinstall the caliper over the new pads and torque the bolts to manufacturer specifications.

5. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors: Look for deep grooves or warping. If damaged, replace.
Replace Rotors:
1. Remove the caliper bracket by unscrewing its bolts.
2. Slide off the old rotor.
3. Clean the hub surface with brake cleaner.
4. Install the new rotor, ensuring it is seated properly.
5. Reattach the caliper bracket and torque to specifications.

6. Reassemble the Wheel

Place the wheel back onto the hub.
Hand-tighten the lug nuts before lowering the vehicle.
Once lowered, use a torque wrench to tighten the lug nuts to the manufacturer’s specifications.

7. Final Checks

Reconnect the battery.
Press the brake pedal several times to ensure proper pad seating.
Check brake fluid levels and top off if necessary.
