CastrolSRF Racing Brake Fluid - 1 Liter 12512

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.

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.

This stuff is awesome.....zero break fade.

As an HPDE race track instructor I ride in a lot of cars, many suffer brake fade related to boiling fluid. We have a race engineer on site that changes out/bleeds fluid on these cars. Never had a subsequent problem. The specs on this fluid is outstanding. Expensive, yes but when you need to hit the brakes and trust you will slow down the is the stuff that will give you piece of mind

Held up 3x20 sessions during warm days in my RSX. Couple of heavy braking zones including a 120-60 mph one and I didn’t ever have fluid boiling issues.

Castrol is one of several high boiling point brake fluids available, however; the only one I use provided it’s available. It is NOT the lowest cost but braking matters most when in track.

Good price and fast shipping.
