If there is a problem of vapor lock in break system.

Can any one tell me how to over come this problem.

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.

The vapor lock is due to continuous application of brake the liquid will becomes vapor, so that vapor lock will occurs.

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.

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.

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.

Due to continuous application of the brake, the temperature of the brake fluid raised. So in some particular cases the brake fluid vaporizes and causes vapour lock.

The vapour lock may occur because of high temperature in brake system due to any reasons either environmental or brake applications but in rare cases because brake fluid has the quality to withstand very high temperatures, in my career I have not come across any brake fluid vapour lock though it may occur in fuel systems.

Its a not a possible. Now a days in the ferrari car has a automatic brakes which work when any vehicle crosses very near to ferrari its brakes automatic work.

Vapor lock is a problem that mostly affects gasoline-fueled internal combustion engines.

It occurs when the liquid fuel changes state from liquid to gas while still in the fuel delivery system. This disrupts the operation of the fuel pump, causing loss of feed pressure to the carburetor or fuel injection system, resulting in transient loss of power or complete stalling. Restarting the engine from this state may be difficult.

The fuel can vaporize due to being heated by the engine, by the local climate or due to a lower boiling point at high altitude. In regions where higher volatility fuels are used during the winter to improve the starting of the engine, the use of "winter" fuels during the summer can cause vapor lock to occur more readily.
