Solution

1. Preparation

Gather tools and safety equipment: jack stands, wheel chocks, gloves, and safety glasses.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which brakes are making noise.
Place jack stands securely under the vehicle to ensure stability.

3. Remove Wheel

Use a socket set to remove the lug nuts from the wheel.
Take off the wheel to access the brake components.

4. Inspect and Replace Brake Pads

Examine brake pads for thickness; if less than 3mm, replace them.
If replacing, remove the caliper bolts with a socket set and lift the caliper away from the rotor.
Replace old pads with new ones, ensuring proper orientation.
Reinstall the caliper and torque the bolts to manufacturer specifications (typically around 25-35 ft-lbs).

5. Inspect and Replace Brake Rotors (if necessary)

Check rotors for scoring or warping; if damaged, replace them.
Remove the rotor by unscrewing the retaining screws (if applicable) and sliding it off the hub.
Install new rotors, ensuring they are properly seated and secure.

6. Reassemble and Lower Vehicle

Reinstall the wheel and torque the lug nuts to the manufacturer's specifications (usually 80-100 ft-lbs).
Lower the vehicle back to the ground and remove jack stands.

7. Brake Fluid Check and Bleed

If brake fluid is contaminated or low, replace it.
Bleed the brakes to ensure no air is trapped in the system, using a brake bleeder kit.
