Brembo Dot 4 brake fluid has a higher boiling point than other Dot 4 brake fluids available on the market. Due to having a higher boiling point, systems equipped with this fluid have less of a likelihood of going into vapour lock during use.
Over time, brake fluid absorbs water in the air, causing the boiling point to be brought down. Starting with a high boiling point helps to keep the car's stopping ability effective over a longer period of time. Also, as a note, brake fluid should be drained and replaced every few years (due to the water absorption).
