Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and the vehicle is secure.

2. Inspect and Top Off Brake Fluid

Tools Required: Brake fluid, funnel
Check the brake fluid reservoir for low fluid levels.
If low, add the recommended brake fluid (DOT 3 or DOT 4) to the proper level.
Close the reservoir cap securely.

3. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench, clear tubing
Start with the wheel farthest from the master cylinder (usually the right rear).
Attach the clear tubing to the bleeder valve and place the other end in a container.
Loosen the bleeder valve using a wrench and have an assistant press the brake pedal.
Tighten the bleeder valve before the pedal is released to prevent air from entering.
Repeat until no air bubbles appear in the tubing.
Proceed to the left rear, right front, and finally left front in the same manner.

4. Inspect Brake Components

Tools Required: Jack, jack stands, lug wrench
Lift the vehicle and remove the wheels.
Inspect brake pads for thickness; replace if worn down.
Check rotors for scoring and warping; replace if necessary.
Ensure calipers are functioning properly without leaks.

5. Replace Any Damaged Components

Tools Required: Socket set, torque wrench
Replace any damaged brake lines, calipers, or pads as needed.
Follow manufacturer specifications for torque settings when reinstalling components.
