Solution

1. Preparation

Gather tools: brake fluid, OBD-II scanner, brake bleeder kit, wrenches, socket set, and a torque wrench.
Ensure the vehicle is parked on a level surface and engage the parking brake.

2. Inspect Brake Fluid Level

Open the hood and locate the brake master cylinder.
Check the brake fluid level; if it's low, fill it with the recommended brake fluid type (DOT 3 or DOT 4).
If fluid is low, inspect for leaks in the brake lines and connections.

3. Bleed the Brake System

Start with the wheel farthest from the master cylinder (usually the rear passenger side).
Attach the brake bleeder kit to the brake caliper's bleeder screw.
Have an assistant press the brake pedal while you open the bleeder screw to release air and fluid.
Close the bleeder screw before the assistant releases the brake pedal.
Repeat this process for each wheel (rear passenger, rear driver, front passenger, front driver) until no air bubbles are present in the fluid.

4. Inspect Brake Components

Remove the wheel to access the brake assembly.
Check the brake pads for wear; replace if they are worn down to the indicator.
Inspect the brake rotors for scoring or warping; replace if necessary.
Reassemble the wheels and ensure all components are torqued to manufacturer specifications.
