SYSTEM braking on motor vehicles is clearly not familiar with the standard and luxury cars, antique cars and the output current. Anyway, when driven at high speeds or when walking slowly, the vehicle must be stopped because it had to be stopped or because there is an obstacle that suddenly appeared in front of the vehicle.
IF offensive braking system, in addition to a number of devices that are attached to the vehicle such as using a drum brake system or use a disc (disc brake), it still brake fluid (brake fluid) are the mainstay of which should receive attention, particularly related to the time of the traction braking.
The presence of imported cars or cars with cutting-edge engine technology powered lately emphasized to the owners or drivers of motor vehicles for a more detailed understanding of what it called the brake fluid. This warning is important not to suddenly when the brake pedal, the car continues to move reluctant to be stopped.
It's nothing, especially imported cars, with a large capacity engine power, braking systems clearly need a more adequate and more reliable. Moreover, the car has antilock brake system using the system (ABS). This is closely related to the type of brake fluid is used, which is certainly different from the brake fluid used a variety of small motorized vehicles are mostly standard passing on the road this country.
"Usually a car with ABS systems use a type of brake fluid with DOT higher," said Soelistyo Wibowo, a mechanic who had been handling the cars output PT Indomobil Suzuki International Commerce. DOT department of transportation is the alias on the classification of brake fluid which obviously can not be ignored.
DOT has become increasingly important as today's latest cars are not just using the ABS system, but is equipped with electronic brake-force distribution (EBD) which electronically helps distribute brake fluid to each wheel so as to obtain an equivalent braking system. This prevents the brakes when the car spun.
DOT Classification quality shows the existing brake fluid, which means also the ability in the effectiveness of vehicle braking. "The cars with large engine power obviously requires DOT brake fluid with a higher classification because it can last up to a very high boiling point which occurs during braking," said Basuki Rachmad, manager of product planning at PT Toyota Astra Motor.
Brake fluid is glycol ether-based chemicals capable of reaching the boiling point to 250 degrees Celsius. "Because at the time of braking when the car in high speed, the temperature in the drum, brake lining, brake fluid and can reach very high temperatures. Anyway at night brake lining could be seen glowing red," said Basuki Rachmad encountered during the launch of Toyota Avanza earlier this year.
Classification of brake fluid commonly found in the market is DOT 3. Standard cars, such as Japan car output, typically using DOT 3 brake fluid this classification. The latest cars with a great engine technology with tremendous power output requires a higher DOT classification, such as DOT 4 or DOT 5.
European output of cars or the United States (U.S.), for example, most have used DOT 4. Can not be denied, the car with the use of DOT 4 brake fluid types will feel lighter in braking. Power grip is also more effective. Similarly, the brake fluid DOT 5 or higher.
That said, racing Formula I cars, known as the pole using the brake fluid with DOT classification of 6 or 7. Thus, when Michael Schumacher in his Ferrari, he could immediately reduce the rate of the car is being driven at speeds approaching 300 kilometers per hour. Remain functional brake Formula I even put a halt to the boiling point was reached very high, knowing that the speed of close to 300 kilometers per hour.
Intriguing question, whether the car with DOT 3 brake fluid types can be replaced with DOT 4 brake fluid
or let the higher the braking effectiveness? Or conversely, a car that uses a type of DOT 4 brake fluid is used as the output current cars of Europe or the U.S. can not simply be replaced with DOT 3 brake fluid type?
"You'd better stick with the recommended type of brake fluid manufacturers," said Wibowo Soelistyo as he claimed not to know what effect if replace the type of DOT 3 brake fluid to DOT 4 or vice versa. "Clearly, the suggestion of using the plant type DOT 3 brake fluid because it has adapted to the various braking systems devices, such as pipes or rubber on the brake master," he said.
A definite type of DOT 3 brake fluid has a boiling point and viscosity (viscosity) at high and low temperatures are different types of DOT 4 brake fluid. These differences also affect the ability of the brake fluid in brake components to protect from rust. Chemical compounds in brake fluid, such as antioxidants and antifoam, useful or rubber seals to protect the lasting power. In fact, these compounds can also minimize the presence of air bubbles in the pipeline or that could result in brake master brake tension.
If so, of course, the desire to replace the owner or driver of DOT 3 brake fluid to DOT 4 brake so that the grip is actually wrong. That may occur, use DOT 4 with a higher quality chemical compounds can cause the brake pipeline ruptured due to the ability of a high boiling point and the pressure that comes across clearly higher than DOT 3 brake fluid. Thus, the mean brake also be relieved.
So it is taboo if you use DOT 4 brake fluid type and then going to be replaced with DOT 3 brake fluid. What happens is that the braking effectiveness is reduced because the driving force and a lower boiling point. In fact, cars with DOT 4 brake fluid are the cars with large engine power capabilities and thus require a more adequate braking effectiveness. Not to mention the demands of the latest technology in braking systems, such as ABS and EBD.
Long story short, often car owners, especially of the upper classes, entrusting his vehicle maintenance is included in the brake fluid to the authorized repair shop. Thus, the guarantee will be used brake fluid remain as recommended by the manufacturer. However, not infrequently there are persons, whether drivers or workers' workshop, a rogue. Understandably, DOT 4 brake fluid type or types of higher DOT rare and more expensive too. So, it should be aware. (Pieter P Gero)
