Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the negative battery terminal to ensure safety.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes are squealing.
Secure the vehicle with jack stands for safety.

3. Remove Wheel

Use a lug wrench to remove the lug nuts and take off the wheel.
Store lug nuts in a safe place to avoid losing them.

4. Inspect and Remove Brake Components

Remove the caliper bolts using a socket set.
Carefully lift the caliper off the rotor and secure it in place with a bungee cord (do not let it hang from the brake line).
Inspect the brake pads for wear. If they are less than 3mm thick, they should be replaced.
Remove the brake pads from the caliper bracket.

5. Replace Brake Pads (if necessary)

If new pads are needed, install them in the caliper bracket, ensuring they are properly seated.
If using new pads, apply brake grease to the backing of the pads and any contact points to reduce noise.

6. Reassemble Brake Components

Reinstall the caliper over the new or inspected brake pads.
Tighten the caliper bolts to the manufacturer's specified torque value (refer to service manual, typically around 25-35 Nm).
Reinstall the wheel and hand-tighten the lug nuts.

7. Lower the Vehicle

Carefully remove the jack stands and lower the vehicle back to the ground.
Re-torque the lug nuts to the manufacturer's specifications (usually around 90-100 Nm).

8. Test Brakes

Reconnect the negative battery terminal.
Start the vehicle and pump the brake pedal a few times to ensure proper brake engagement.
