From the Technical Datasheet:

Racing Brake Fluid 660 Factory Line
  • 100% Synthetic Racing Fluid ? DOT 4
  • Very high boiling point: 328°C / 622°F
For hydraulic actuated brake and clutch systems

TYPE OF USE

All types of hydraulic brake and clutch actuators requiring non-silicone synthetic fluid.
Specially designed to resist to extreme temperature generated by racing carbon and ceramic brakes allowing minimizing air entrance for brake cooling.
Can be also used with conventional steel discs and clutch systems actuators.
Widely exceeds DOT 3, DOT 4 and DOT 5.1 standards (except for DOT 5.1 viscosity at - 40°C).

PERFORMANCES
  • STANDARDS FMVSS 116 DOT 4 / SAE J1703
Extreme thermal resistance and stability:
MOTUL RBF 660 FACTORY LINE very high boiling point (328°C / 622°F) is superior to conventional brake fluids DOT 5.1 (260°C / 500°F mini) and DOT 4 (230°C / 446°F mini), and therefore enableseffective braking even in extreme conditions.
Provides better aerodynamic performance by reducing air entrance for brake cooling on cars.

Efficient when rainy:
MOTUL RBF 660 FACTORY LINE very high wet boiling point (204°C / 399°F) is superior to conventional brake fluids DOT 5.1 non-silicone base (180°C / 356°F mini) and DOT 4 (155°C / 311°F mini), and therefore enables to keep efficient braking in wet conditions. Brake fluids tend to absorb humidity from the air, which reduce boiling point and increase the risk to get
to ?vapor lock? phenomena.The wet boiling point is measured by humidifying the product with 3% of water.

RECOMMENDATIONS
  • Avoid mixing with polyglycol based brake fluids.
  • Do not mix with silicone (DOT 5 silicone base) or mineral base fluids (LHM).
  • Store brake fluid in its original container, tightly closed to prevent moisture absorption.
  • Aggressive chemical product if contact with hands, paint or varnish.
  • If skin contact, rinse thoroughly with water.

Important warning! Risk of injury!

General:

  • When using our products, it is important to follow the instructions for installation and manual and the warnings associated with them.
  • Special care must be taken while handling with electricity.
  • When driving on the road, always observe the locally valid laws and regulations!
  • Ensure that you wear adequate protective clothing
  • If the vehicle is damaged, it may not be driven under any circumstances. Danger of injury!

Mounting:

  • Always switch off your electric vehicle and disconnect the power cable before carrying out maintenance work or replacing parts or accessories.
  • Remove both batteries / accumulators before starting work.
  • PT Pro is generally not liable for damage caused by incorrectly installed attachments, wear and spare parts.
  • Always read the latest authorized operating and installation instructions before installation
  • In order to avoid damage and malfunctions, installation should only be carried out by qualified personnel! Incorrect mounting can lead to death or serious injury.
  • To minimize the risk of injury, please read and follow all instructions and warnings in the user documentation

Driving the vehicle:

  • Use of the vehicle can become deadly or result in serious injury due to loss of control, collisions and falls.
  • To minimize the risk of injury, read and follow all instructions and warnings in the user documentation.
  • PT Pro recommends that you always wear a helmet when driving the vehicle.
  • When using the vehicle, the current road traffic regulations in the respective country must be observed
  • Always store batteries and accumulators in a dry place and at room temperature (10 - 25 degrees)
  • Charge batteries only at adequately fused sockets and with charging cables designed for this purpose
  • Protect batteries and their connectors from moisture
  • Always switch off your electric vehicle and disconnect the power cable before carrying out maintenance work or replacing parts or accessories.
  • Remove both batteries / accumulators before starting work
  • Do not clean with steam jet or garden hose or drive through deep puddles! Clean with a damp cloth!

Lamps:

  • Please always ensure sufficient battery power for the duration of your ride.
  • Never look directly into the light source. This can lead to blindness

Rims:

  • Important: Risk of crashing:
  • Check rims for damage before every ride!
  • Rims with out-of-balance or which show knocks, hairline cracks and deformation must be replaced immediately.
  • Hairline cracks are difficult to detect, danger of breaking! Hairline cracks are possible, especially after accidents and after riding fast over high edges (high pavement, thick roots etc.). Here you save at the wrong place!
  • Regularly check the screw connection of the rims!
  • Never use rims as load securing points (lashing strap!). Lateral tension forces can damage the rim.

Helmets:

  • Caution: Not suitable for motorcycling!
  • Please read the warnings inside the helmet!
  • Only wear the helmet while riding. Danger of strangulation due to getting caught on the chinstrap when climbing or playing.
  • The helmet can no longer fulfil its protective function after a fall, so replace it after every fall.
  • Materials age due to UV radiation and external influences. To ensure optimum protection, safety helmets should always be replaced after approx. 5 years.


Caution: 
Electronic components are generally excluded from return, cancellation and conversion, as these are specific individual productions due to the respective programming of the component or customer-specific optimizations. Complaints can only be accepted if the component was installed by a trained PT Pro technician. In case of self-installation, any form of warranty or guarantee expires. We refer here to § 312g paragraph 2 BGB additionally apply: I. Exclusion already before the beginning of the production of the goods II.
