Oil contamination reduces the boiling temperature of water. Air bubble formation loss of braking effect when overheating.
Cars run about 16,000 to 25,000 km per year, and the driver to brake about 75,000 times. Nearly half of drivers questioned in the Car Care Council survey said they had a panic because of faulty brakes.
About half of all cars and trucks in the U.S. uses over 10 ever changing brake fluid. Many countries in Europe have asked periodically to check brake fluid, almost half of them have found fault.
Brake fluid plays an important role for the maintenance of safe driving. Experts recommend technology, vehicle owners should replace the brake fluid if they are infected, contaminated or replaced periodically 1-2 years.
The reason that experts give is because the brake fluid containing glycol. This is a powerful desiccant. Over time the steam can penetrate through the rubber hose washers. This phenomenon appears clearly if vehicle use in an environment of high humidity.
Brake fluid can infect up to 2% after 1 year of use, 3% after 18 months. Would not be difficult to find the oil samples and 7-8% water if the vehicle has used a few years.
According to a Commission investigation of the National Transportation Safety U.S., 20% of 1720 vehicles with brake fluid and water more than 5%. Oil and water have lower boiling oil "dry". DOT 3 boiling oil at 205 degrees C, as when wet they were as 140 degrees C. Boiling oil of most new DOT at about 240 to 260 degrees C.
And 1% water, the boiling temperature of 187 degrees C. DOT 3 also Infection of 2% is 160 degrees C. If 3% of oil will boil at 145 degrees C.
DOT 4 oil moisture more slowly, but boiling temperature decreases more than DOT 3. If infected with 3% water, the boiling temperature of the DOT 4 can be reduced by half.
Brake system overheating that creates bubbles boiling oil. Occupancy of oil in the system liquid, air bubbles disable the braking system brakes despite stringent driver. Besides, oil and water transitions promote corrosive elements brakes, ABS.
Brake system with oil and water easily pass safety tests. Oil level remains within the allowable limit, well pipe, the brakes still work. But all will change when the heating system and air bubbles to form.
