TAROX RoadRace


TAROX RoadRace brake fluid has been specially formulated to offer the best of both worlds: it delivers outstanding performance under racing conditions where braking systems must operate at very high temperatures, yet it is suitable for every day use where it is essential that a brake fluid conforms to the requirements of car manufacturers. Its high boiling point in excess of 300°C makes it ideal for virtually every race condition.


  • Follow vehicle manufacturers recommendations when adding brake fluid.
  • Keep brake fluid clean and dry – contamination with dirt, water, petroleum products or other materials may result in brake failure or costly repairs.
  • Store brake fluid only in its original container.
  • Keep container clean and tightly closed to prevent absorption of water.
  • Do not refill container and do not fill with other liquids.
  • Dispose of used brake fluid responsibly (EU waste code 16 01 13)
  • Not suitable for use with high Magnesium content alloy brake components.
  • For best results bleed the system with fresh fluid from a sealed container before each race,
  • especially if the brakes are excessively hot and/or the conditions are humid.
  • Do not mix with other brake fluids.


  • Keep out of reach of children.
  • Irritating to eyes. Harmful to aquatic organisms.
  • Contains polyalkylene glycol ethers and ether esters. Do not swallow.
    If swallowed, call medical assistance immediately and show this container.
  • Avoid skin and eye contact. In case of eye contact flush with plenty of water for 10 minutes.
    If irritation persists, seek medical advice
  • Do not empty into drains
  • Brake fluid will damage paintwork and other components including brake calipers. If spilt wash off immediately with plenty of water.


How does TAROX RoadRace compares with DOT 4 and DOT 5.1 fluids?

TAROX RoadRace meets and exceeds the current DOT 4 specification which covers a huge range of brake fluids with widely differing properties. DOT 4 brake fluid boiling points for example will range from a minimum of 230°C to over 300°C like TAROX RoadRace. DOT 5.1 fluids are not designed to have particularly high boiling points – a figure of around 270°C being typical. Their main advantage is improved low-temperature viscosity which is only relevant in very cold climates where vehicles are using ESP systems. This means that they are fluids designed for road use rather than track use. TAROX RoadRace is a much better track/road compromise than a DOT 5.1 – boiling point being a far bigger problem on the track,
than low temperature viscosity is on the roads.

Why is it road legal?

TAROX RoadRace brake fluid is road legal in the United States and Canada because it meets the requirements of the FMVSS 116 DOT 4 standard. It is also legal for road use in Spain because it meets the requirements of the UNE 26-109-88. The USA, Canada and Spain are almost unique in specifying minimum performance requirements for brake fluids that are to be used on public roads. Most other countries take the view that the product must be fit for the purpose which is demonstrated by conformance to the main brake fluid standards. Most vehicle manufacturers in Europe recommend brake fluids that conform to DOT 4.

What is the recommended service interval?

When TAROX RoadRace brake fluid is being used on the road, it is advised to keep following manufacturers recommended change times and obtain the benefit of the extra safety margin provided.

What about the usage in race conditions?

For best results bleed the system with fresh fluid before each race, especially if the brakes are excessively hot and/or the conditions are humid. Do not mix with other brake fluids.

When is TAROX RoadRace brake fluid not recommended?

Firstly, it cannot be used for those vehicles requiring a mineral based fluid (LHM). Secondly, it not recommended for older classic cars produced before 1970. Even here in almost all cases the product can be used perfectly satisfactorily but a very few older cars (especially in the United States) used seals which can perform poorly with high-performance fluid such as TAROX RoadRace. A high boiling DOT 3 fluid is usually more appropriate in these cases.
