High performance isn’t just about making cars go faster. It’s also about ensuring they stop safely.
Never take a break from checking brake fluid. Make it part of every service.
At Castrol, and in Castrol partner workshops, we know high performance isn’t just about making cars go faster.
It’s also about ensuring they stop safely.
But even though brake fluid maintenance should be done as part of the regular vehicle service, 1 in 4 vehicles on the road have been found to have ineffective brake fluid. [1]
The problem is that brake fluid absorbs moisture as it ages. As little as 3.5% water can reduce brake fluid effectiveness by up to 40%. [2]
Castrol Brakes
CHECK IT.
Most manufacturers recommend a brake fluid change every 24 months but at Castrol we suggest checking at every service. Ideally with a professional testing machine.
CHANGE IT
Anything over 2.5% water content we’d recommend draining and changing the brake fluid. Over 3% water content and changing is essential.
TRUST IT
Castrol brake fluids are available in a range of formulations to suit every type of vehicle and driving situation.
Our fluids are engineered to have higher boiling points than standard fluids, providing extra assurance of brake fluid performance.
Giving you, and your customers, confidence that the vehicle can stop safely when out on the road.
Or even out on the racetrack.
Never take a break from checking brake fluid. Make it part of every service.
Check it.

What do Brake Fluid DOT ratings mean?
All forms of brake fluid are given a DOT rating. DOT simply stands for ‘Department of Transport’, which sets the safety regulations for the acceptable performance of different brake fluids. The DOT ratings given to brake fluids are based on the liquid’s dry and wet boiling points. As a rule of thumb, the higher the boiling point, the longer the lifespan of the brake fluid.
A polyglycol type brake fluid formulated to provide extra braking performance under normal driving conditions.
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).
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.
Recommended where DOT 3 brake fluids are preferred. Certain older Japanese vehicles may stipulate DOT 3 brake fluids.
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.
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).
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.
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”
Castrol React SRF Racing is suitable for all disc and drum brake systems used in motorsport with the exception of those for which a mineral oil is prescribed. lt complies with the requirements of the following specification:
