Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface, and the engine is off.
Use wheel chocks to prevent the vehicle from rolling.
Tools Required: Brake fluid, wrench set, brake bleeder kit, jack and jack stands, OBD-II scanner.

2. Check and Refill Brake Fluid

Open the hood and locate the brake master cylinder.
Remove the cap and check the brake fluid level.
If low, add the recommended brake fluid type (usually DOT 3 or DOT 4).
Replace the cap securely.

3. Bleed the Brake System

Begin at the wheel furthest from the master cylinder (typically the rear passenger side).
Attach the brake bleeder kit to the brake bleeder valve on the brake caliper.
Have an assistant pump the brake pedal several times and hold it down.
Open the bleeder valve to release air and old fluid, then close it before the assistant releases the pedal.
Repeat the process until no air bubbles are present in the fluid.
Move to the next wheel (rear driver side, front passenger side, then front driver side) and repeat.

4. Inspect and Replace Brake Components (if necessary)

If sponginess persists, inspect the brake master cylinder for leaks or internal failure.
If damaged, remove it by disconnecting the brake lines and unbolting it from the firewall.
Install the new master cylinder, reconnect brake lines, and bleed the system again.

5. Final Assembly

Ensure all components are securely fastened and fluid levels are correct.
Recheck all brake connections for leaks.
