Diagnostic Steps

1
Inspect brake pads for wear; check for thickness and uneven wear patterns.
2
Check brake rotors for scoring, warping, or uneven surfaces.
3
Examine brake calipers for proper operation and any signs of sticking.
4
Inspect brake lines for leaks or damage.
5

Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety goggles.
Safety Warnings: Ensure the vehicle is on a flat surface. Engage the parking brake and wear safety goggles.

2. Raise the Vehicle

Use the lug wrench to loosen the lug nuts slightly while the vehicle is on the ground.
Lift the vehicle using a jack and securely place it on jack stands.
Remove the wheel to access the brake components.

3. Inspect and Replace Brake Pads

Remove the caliper by unbolting it from its mount using the socket set.
Carefully slide the caliper off the rotor and support it with a bungee cord to avoid straining the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the brake pad friction material; if it is worn down to the indicator, replace it with new pads.
Apply a thin layer of brake grease to the back of the new pads to prevent squeaking.
Reinstall the new brake pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for any grooves or uneven wear. If damaged, replace the rotor.
Remove the rotor by unbolting it from the hub if it's not sliding off easily.
Install the new rotor and secure it with the appropriate torque specifications (usually around 80-100 lb-ft, but refer to the vehicle's service manual for specific values).

5. Reassemble and Test

Reattach the brake caliper over the new pads and torque the bolts to the manufacturer's specifications.
Reinstall the wheel and torque the lug nuts in a crisscross pattern to ensure even tightness.
Lower the vehicle and pump the brake pedal several times to seat the pads against the rotor.
Test drive the vehicle at low speeds to ensure the noise is gone and the brakes function properly.
