Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Wear safety goggles and gloves.

2. Check and Refill Brake Fluid

Tools Required: Brake fluid, funnel.
Ensure the master cylinder cap is clean before opening.
Check the brake fluid level; if low, refill with the appropriate brake fluid type (DOT 3 or DOT 4 as specified in the owner's manual).

3. Inspect for Leaks

Tools Required: Flashlight.
Visually inspect brake lines, calipers, and wheel cylinders for any signs of fluid leakage.
Tighten any loose connections and replace any damaged components as necessary.

4. Bleed the Brake System

Tools Required: Brake bleeder kit, wrench.
Start with the wheel farthest from the master cylinder (usually the right rear).
Attach the bleeder kit to the bleeder valve on the brake caliper.
Open the valve and have an assistant slowly press the brake pedal until fluid flows without air bubbles. Close the valve and repeat until no air bubbles are present.
Repeat for each wheel in the following order: right rear, left rear, right front, left front.

5. Inspect and Replace Components (if necessary)

Tools Required: Socket set, torque wrench, replacement brake pads/rotors (if worn).
Remove the wheel to access the brake components.
Inspect the brake pads and rotors for wear; replace them if they are below the manufacturer's specifications.
Reassemble the brake components and torque to specified values, usually found in the service manual.

6. Test Drive

After completing repairs, take the vehicle for a short test drive to ensure the brakes are functioning properly.
