There is no chance for vapour lock in brakes, now days the brake liquids are manufactured to withstand HIGH TEMPERATURE and there is no DIRECT contact between the BRAKE OIL and BRAKE SHOES.
So the temperature is created by the pressure is within the temperature limit of the Brake oil.

While overheating of brake or disc brake, the molecules in chamber or disturbed and some of ingredients, dust and moisture will disturb the brake pad of vehicle.
This results in the vapour locking or some disturbance which results in anti locking of the brake system.

This is basically related to the brake fluid.
Due to their hygroscopic nature they absorb moisture from atmosphere resulting in decrease in boiling temperature and hence changing the fluid in vapour state. As vapour is highly compressible the brake stops working.

Although brake fluids are designed to work at extreme temperatures above 250C but still as the age of brake fluids goes on increasing, it starts loosing its properties and hence under high pressure and temperatures developed by applying brakes causes vapour lock.

Brake fluid like many other fluids expands under severe and continuous pressure and this give rise to the formation of vapour due to rise in temperature and the resultant effect is that it make brakes ineffective due to vapour lock.

@ALL.
Present days the fluid systems are increased to stable the heavy heat resistance. Incase of vapour locking the fluid gets very fast time take to the original state.
Give me some examples to present vehicles if fassible?

When the brake is applied than break shoes is heated in contact shoes and brake drum to decrease to speed than vapour generated than some fluid also vaporized vapour is locked in drum and shoes.

Please clarify the concept of vapour lock.
Whether it occurs due to temp rise by frequent operation of the system or by hygroscopic nature of brake fluid? Or both?
