CastrolSRF Racing Brake Fluid - 1 Liter 12512

If you have a sports car and you track it, a brake failure or spongy brake pedal could cost you your ride. Proper maintenance of a brake system goes a LONG way, but good brake fluid can help too. If you don't know about brake fluids, Castrol SRF is about as good as it gets before you get into extremely hard to find and expensive racing brake fluids that don't last very long because they attract a ton of moisture.It has a wet boiling point of 518F, which is about 80-120 degrees higher than any other mainstream brake fluid. But this wont matter unless you are getting your brakes REALLY hot, like a track or HPDE.Always remember Brake fluid is highly corrosive, never let it sit on any painted surface and throw away any rags you wipe up break fluid with.

Not much needed to say, Castrol is the best fluid I've tried. Lasts much longer than motul 600, 660, etc.

This DOT4 high temp brake fluid is excellent quality. I track my car quite regularly and have never once had my brake fluid boil. I highly recommend it, however if you track your vehicle or drive heavily in the mountains it's important that you flush your brake fluid every 30k miles, regardless of brand.

Look for the wet boiling points for comparisons. This brake fluid is the best I have found. Compared to RBF600, the dry boiling points (when new) were roughly the same, but the wet boiling points (after they absorbed some moisture) are very different. This was called out specifically in my Aston Martin owner's manual.

Best brake fluid on the market

Because this stuff doesn't attract moisture as quickly as most high temp brake fluids do, you don't need to flush your brakes as often as you maybe once did. This helps offset the higher cost of this fluid compared to Motul RBF600 and similar brake fluids, as well as the lightened load of manual labor needed to dedicate to brake flushes. I've tested this in my new Civic Type R at the race track, and I was impressed with this fluid's performance. Glad I found it, and I notice a lot of my fellow track day drivers are switching over to it as well.

Good price and fast shipping.
