Which is the right brake fluid for my car?
When should I replace it ? Are brake fluids interchangeable ?
To serve correctly, the braking system not only depends on the alimony of its mechanical and hydraulic components, but besides on the condition of the brake fluid. The brake arrangement relies on the incompressible nature of the brake fluid to efficiently transmit coerce from the brake pedal into hydraulic imperativeness to the brake caliper, for the brakes to apply in order to slow down or stop your vehicle.

In addition to this brake fluid must have a high boiling point to prevent boiling when exposed to high temperatures from braking .
If the brake fluid boils, it evaporates into vapor and vaporization is compressible. If this happens the pedal will be compressing vapour and not transmitting the impel to the brakes, which means slower reply when braking that can prove fatal !
Brake fluid isalso required to keep the braking system lubricated and preserving its components against corrosion .
When should I replace it ?
The recommend intervals for changing brake fluid are normally specified by the Manufacturer however may vary pendent on the type of fluid that is used.
99 % of the car-park use brake fluid that is glycol based and is highly hygroscopic, which means that they absorb moisture from the atmosphere. Due to its hygroscopic nature, brake fluid tends to absorb external moisture through the porosity of brake hoses. This deteriorates its condition, lowering the churn point. Therefore brake fluid that has been in a vehicle for 3 years or longer has a well lower boiling decimal point than brand modern brake fluid from an unopened bottle. Having a abject boiling point as mentioned previously leads to a reduced response when brake and, in some cases, pressing the brake pedal has no effect : called the Vapour Lock. Vapour Lock occurs when moisture in the brake system turns to steam when heated significantly, causing “ compressibility ” of the brake fluid Brake fluid should ideally be clear and clean. Dark and cloudy brake fluid indicates that it has accumulated impurities and that it ’ mho time to be replaced

Which brake fluid is right for my vehicle ?
Consult your vehicle ‘s service manual to help choose the properly DOT rated fluid for your fomite. Using a DOT rated fluid other than what is recommended may cause improper brake operation .
generally, glycol-based DOT 3, DOT 4 and DOT 4 Low viscosity brake fluids meet the technical requirements of 90 % of cars on the road today.
Brembo DOT 4 brake fluid is desirable for use on most vehicles that use glycol based fluid, from the oldest to the most holocene models, including those fitted with anti-lock braking systems ( ABS ).
For latest-generation cars, with ABS systems for constancy or grip control systems ( ESP, ASR, TCS, EBD ), we recommend the Brembo DOT 4 LV ( Low viscosity ) brake fluid. Brembo DOT 4 LV ( Low viscosity ) brake fluid maintains uniform viscosity even at low temperatures. In these electronic systems, the fluid flows through control mechanisms where there are valves with very narrow-minded passageways and it is full of life for the fluid to maintain its viscosity, to flow smoothly for the precise and immediate transfer of atmospheric pressure.
For drivers with high performance vehicles that produce even higher brake temperatures, Brembo recommend using DOT5.1 with higher seethe points however, owing to its characteristics, requires more detail maintenance than DOT 4 fluids .
Are bracken fluids exchangeable ?
car braking systems are manufactured to use a specific type of fluid. Therefore it is crucial that the vehicle should continue to use that particular type of fluid for the remainder of its serve life. This is crucial as the inner components of the brake system have been designed, selected and tested to operate with that finical fluid. Although DOT 3 and DOT 4 fluids are all glycol-based, the chemical writing of each type of fluid is different, so it will have a different effect on the organization. To ensure that the system works as it should, it is imperative to keep using the exact brake fluid recommended by the manufacturer .
