What is the main cause of brake fade?
Brake Fluid Fade: Brake fluid fade can happen when water in the vehicle’s brake fluid overheats from all the friction. That overheated water boils into steam, which reduces the effectiveness of your brakes. When brake fluid fade occurs, pressing down on the brake pedal may result in a soft or “spongy” feeling.

What causes spongy braking in a hygroscopic car?
As the brake fluid is Hygroscopic it draws in water which has very different characteristics to brake fluid when it comes to boiling points. The water within the brake fluid boils and releases gases (steam) causing spongy braking as unlike fluids gases are compressible.
