BRAKE FLUIDS

Brakes are essential for any car as it is not possible to stop without them. Choosing the right brake fluid for your car’s requirements and changing it on time is critical to safety. Castrol’s brake fluid range includes products for high performance cars, driving under demanding conditions, to products with increased safety margin.

Castrol Dot 4 Brake Fluid

CASTROL BRAKE FLUID DOT 4

CASTROL BRAKE FLUID DOT 4

A polyglycol type brake fluid formulated to provide extra braking performance under normal driving conditions.


Application


Suitable for use in all brake fluid systems in cars, motorcycles, and light commercial vehicles (LCV’s) requiring either a DOT 3 or DOT 4 product (excluding brake systems where a mineral based fluid is specified).


Features & Benefits

 

  • High boiling point easily meets or exceeds U.S. FMVSS DOT 3 and DOT 4 wet/dry specialisation requirements, and offers a performance reserve over brake fluids with lower boiling points.
  • High vapour lock temperature – greater protection against brake fluid vaporization.
  • Advanced corrosion protection – better protection against corrosion caused by absorbed moisture, that can contribute to lower maintenance costs.
  • High temperature stability – provides a greater margin for safety because the product performance will not fade under higher temperatures.
  • Rubber swell control – contributes to efficient operation of the braking system components.
  • Compatible with all other brake fluids that meet either DOT 3 or DOT 4 Specification.


industry Specifications

 

  • FMVSS 116 DOT 4
  • ISO 4925 Class 4
  • JASO JIS K2233 Class 4
  • SAE J1703
  • SAE J1704
  • AS 1960.1-2005 Grade 2
CASTROL BRAKE FLUID DOT 3

CASTROL BRAKE FLUID DOT 3

A polyglycol based fluid suitable for use in disc and drum brakes and hydraulic clutch systems where a non-petroleum based DOT 3 fluid is specified.


Application


Recommended where DOT 3 brake fluids are preferred. Certain older Japanese vehicles may stipulate DOT 3 brake fluids.


Features & Benefits

 

  • Formulated from mixed polyalkylene glycol esters together with lubricity additives and corrosion inhibitors offering high levels of system protection
  • High level of protection against wear.
  • Fully compatible with other brake fluids meeting FMVSS 116 DOT 3, DOT 4.
  • Proven track record in braking systems over many years of reliable service.


industry Specifications

 

  • FMVSS 116 DOT 3
  • ISO 4925 Class 3
  • JASO JIS K2233 Class 3
  • SAE J1703
  • AS 1960.1-2005 Grade 1
CASTROL REACT PERFORMANCE DOT4

CASTROL REACT PERFORMANCE DOT 4

High performance polyglycol type brake fluid designed to provide superior braking performance in a variety of vehicles, especially those that operate at higher temperatures or under increased loads.


Application


Suitable for use in all brake fluid systems in cars, motorcycles and light commercial vehicles (LCV’s) requiring either a DOT 3, DOT 4 or Super DOT 4 product (excluding those brake systems where a mineral oil based fluid is specified).


Features & Benefits

 

  • High boiling point: Exceeds US FMVSS DOT 3 and DOT 4 specification requirements, and offers a performance reserve over brake fluids with lower boiling points.
  • High vapour lock temperature: Greater protection against brake fluid vaporization.
  • Corrosion protection: Outstanding protection against corrosion caused by absorbed moisture that can cause rusting and failure of components
  • High temperature stability provides a greater margin for safety because product performance will not fade under higher temperatures.
  • Controlled viscosity requirements: Under extreme s of temperature and operating conditions, the product will maintain an optimum operating viscosity to ensure greater safety
  • Rubber swell control: Contributes to efficient operation of the braking system components.
  • Compatible with all other brake fluids that meet either DOT 3, DOT 4 or Super DOT 4 Specifications.


industry Specifications

 

  • FMVSS 116 - DOT 4
  • ISO 4925 Class 4
  • JASO JIS K2233
  • SAE J1703
  • SAE J1704
  • AS 1960.1-2005 Grade 3
CASTROL REACT SRF BRAKE FLUID

CASTROL REACT SRF BRAKE FLUID

High performance brake fluid


The compressibility of Castrol React SRF Racing is very similar to that of current DOT 3 and DOT 4 fluids. It can therefore be filled into any braking system used in motor sport with the exception of those for which a mineral oil is prescribed. It gives a “hard pedal” feel.


Application


For all braking systems where conventional or polyglycol brake fluids are recommended in high performance vehicle and competition applications. Highly recommended for cars used for “Club and Track days”


Features & Benefits

 

  • Widely used in racing, from Formula One, sports cars, V8 Supercar and Grand Prix and Superbike motorcycles.
  • The exceptionally high dry boiling point (higher than 300°C) makes Castrol React SRF Racing ideal for use under arduous braking conditions such as rallying or racing. It exceeds the boiling point requirements of DOT 5 brake fluids.
  • Very high vapour lock point and has the additional advantage of sustaining high vapour lock point characteristics during its service life.
  • It is miscible with all conventional fluids meeting the US Federal Standards FMVSS 116 DOT 3, DOT 4 and DOT 5.1, ISO 4925 and current SAE J1703. This means that changing the brake system to Castrol SRF is easy. Drain and flush out the conventional brake fluid with Castrol SRF then top up the system with Castrol React SRF Racing. Although Castrol React SRF Racing is miscible with conventional brake fluids, topping up Castrol React SRF Racing with conventional brake fluids will reduce the benefits of the product.
  • It is compatible with seal rubber and metal materials used in brake systems using conventional polyglycol brake fluids.
  • It is similar in viscosity to conventional brake fluids so is easy to bleed like conventional brake fluids.
