Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, socket set, brake cleaner, safety goggles, gloves.
Safely park the vehicle on a level surface and engage the parking brake.
Disconnect the battery for safety, especially if electronic brake components are involved.

2. Raise the Vehicle

Loosen the lug nuts on the rear wheels slightly while the car is still on the ground.
Use the jack to raise the rear of the vehicle and secure it with jack stands.
Remove the rear wheels.

3. Inspect Brake Components

Sub-step 1: Check brake pads for wear; they should have sufficient material left (minimum 3mm recommended).
Sub-step 2: Inspect brake rotors for grooves, scoring, or warping.
Sub-step 3: Examine the caliper and brake hardware for any signs of damage or improper installation.

4. Clean and Lubricate

Sub-step 1: Use brake cleaner to remove dust and debris from brake pads and rotors.
Sub-step 2: Apply brake lubricant to the back of the brake pads and any contact points to reduce noise.
Sub-step 3: Ensure all components are free of rust and debris, particularly on the caliper slides.

5. Reassemble and Test

Reinstall the brake components and wheels.
Sub-step 1: Hand-tighten the lug nuts before lowering the vehicle.
Sub-step 2: Lower the vehicle to the ground and torque the lug nuts to the manufacturer's specifications (usually around 80-100 lb-ft).
Sub-step 3: Reconnect the battery.
