6 BRAKE FLUID

Like engine oil, brake fluid is also vehicle specific, putting the wrong fluid into the system can have damaging effects. This can lead to problems with the braking system, ultimately it could cause an accident on the road. The importance of offering the correct brake fluid Most workshops will think that by using DOT 4 they are covered; this couldn’t be further than the truth. DOT 4 LV fluid in newer vehicles Most new cars produced from 2016 onwards have ESP systems. ESP stands for electronic stability program, and it is mandatory requirement in many markets globally.

ESP Systems:

ABS systems control the brakes in the event of a loss of traction during heavy braking, so the driver can still steer the vehicle.

Traction control acts to regulate the power of the engine to the wheels to prevent a loss of traction on low traction surfaces.

When the two systems are integrated, it is normally referred to as an ESP system.

DOT 4 LV is the 1st choice for the Aftermarket as it covers the majority of the mainstream European car parc OEM standards. Why is DOT 4 LV Important? The system must be able to react extremely quickly to be effective and be able to operate at temperatures as low as -40°C. This puts unique demands on the brake fluid, which is the only means that braking force can be transferred around the brake system. A fast system reaction time is only possible with a low viscosity, low compressibility brake fluid, particularly at low temperatures.

The use of a standard DOT 4 brake fluid will impair system performance at lower ambient temperatures as the viscosity is typically much higher.
