Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical issues.

2. Inspect and Refill Brake Fluid

Sub-steps:
- Open the hood and locate the brake fluid reservoir.
- Check the fluid level; if low, top it off with the manufacturer-recommended brake fluid (DOT 3 or DOT 4).
- Inspect for any signs of contamination or discoloration in the fluid.

3. Bleed the Brake System

Sub-steps:
- Locate the brake bleeder screws on each wheel.
- Attach a clear plastic hose to the bleeder screw and place the other end in a container.
- Have an assistant press the brake pedal while you open the bleeder screw, allowing air and old fluid to escape.
- Close the bleeder screw before releasing the brake pedal.
- Repeat this process until no air bubbles are present, starting from the wheel farthest from the master cylinder (usually the right rear) to the closest (left front).

4. Inspect Brake Components

Sub-steps:
- Remove the wheel to access the brake caliper and rotor.
- Check the brake pads for thickness; replace if worn down to the wear indicators.
- Inspect the rotors for scoring or warping; machine or replace as necessary.
- Ensure calipers are functioning properly and not seized.

5. Reassemble and Test

Sub-steps:
- Reattach the wheels and torque the lug nuts to the manufacturer's specifications.
- Reconnect the battery.
- Start the engine and press the brake pedal to ensure it feels firm.
- Conduct a short test drive to verify brake functionality.
