Located in the brake fluid as time passes lose its properties. If it is not replaced on time, the brakes may are unsuccessful with little warning
Typical brake fluids are extremely strong hygroscopic, which absorb moisture through the environment, even when there are within the system. The more water throughout liquid, it has a lower boiling point.
Meanwhile it is the most important parameter! Moisture harms During intense braking fluid gets hot rapidly. The new fluid DOT 4 (normally used in modern cars) includes a melting point more than 230 ° C, it is enough that this water content reaches the approx. 3. 5 percent. This value dropped to approx. 80 ° C.
If the fluid boils and inside the system of gas bubbles appear, then it stops transmit power through the brake pedal to the pistons inside the terminals. The pedal will after that become soft, will "fall to the floor" along with the braking efficiency drops to almost zero.
How to avoid this kind of? At least once each and every two years and for a minimum of 60 thousand. km fluid simply exchanged. Modern cars equipped along with systems EBS, ESP and systems associated with electronic brake force submission are particularly sensitive to fluid quality. For the proper functioning of all of the systems is not adequate, so that the liquid will not boil - it will need to have a suitable viscosity (lower than conventional fluids) permitting rapid pressure changes inside the system.
This example meets what's needed. Bosch brake fluid DEPT OF TRANSPORTATION 4 HP. Using a standard liquid for fractions of seconds can decrease the system - despite appearances in emergency situations greatly! The new cars more difficult in the case of modern cars beyond picking a the correct fluid is important to have a proper procedure for the exchange and venting process.
In many cases, it is necessary to utilize a scan tool through which you can enforce, among others, opening the valves of the hydraulic system in your ABS / ESP. Without this in the trunk of the system may remain used the outdated fluid, and in addition the machine cannot be completely vented, which will result in lower efficiency of the brakes.
According to the professional - Without hardware you don't do this well
The new cars to interchange the brake fluid and bleed the machine requires appropriate equipment. In our
website we always use pressure device that forces the revolutionary fluid and simultaneously catapults the old system.
This eliminates the possibility that the system will be the remnants of the outdated brake fluid and that can't be vented carefully what happens when you will find other methods. The quality of the fluid inside the system can be evaluated by examining its boiling point having a special tool.
It should be recalled, however, that the fluid inside the system are mixed jointly to a limited scope - it happens in which, although the agent within the reservoir has the appropriate parameters, it is the fluid inside the lines and terminals for a longer time requires replacement.
It's worth knowing
Brake fluid should be in keeping with the requirements of producer of the car.
After opening the package fluid begins to absorb water from the oxygen. The measure, which eg. Stood for several years around the shelf in the garage within the opened package is probably not suitable for use.
Fluid from the system mustn't be poured back into the idea.
