Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface, engage the parking brake, and wear safety glasses and gloves.

2. Inspect and Refill Brake Fluid

Tools Required: Brake fluid, funnel, clean rags.
Open the hood and locate the brake fluid reservoir.
Check the fluid level against the "MIN" and "MAX" markings.
If low, use a funnel to add the appropriate brake fluid (DOT 3 or DOT 4 as specified in the owner's manual).
Clean up any spilled fluid as it can damage paint.

3. Inspect Brake Lines and Components

Tools Required: Wrench set, brake line wrench.
Visually inspect all brake lines, hoses, and connections for signs of corrosion, cracks, and leaks.
Tighten any loose connections and replace any damaged components as necessary.

4. Replace Brake Pads and Rotors (if needed)

Tools Required: Socket set, jack stands, brake pad spreader.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access brake components.
Use a socket set to remove the caliper bolts and slide the caliper off the rotor.
Remove old brake pads and inspect rotors for wear.
If rotors are worn beyond the manufacturer's specifications, replace them.
Install new brake pads and reassemble the caliper and wheel.

5. Bleed the Brake System

Tools Required: Brake bleeder kit or clear tubing, container.
Have an assistant pump the brake pedal several times to build pressure.
Open the bleeder valve on the caliper while an assistant holds the pedal down.
Close the valve when fluid flows out without bubbles, then release the pedal.
Repeat this process until all air is removed from the system, topping off the brake fluid as needed.
