Great, Lasts only 1 year
This stuff is amazing! Best wet brake fluid on the market. I highly recommend it, however it does have a few things to worry about: 1) It only lasts 1 year of use. You need to flush the system every year. It gets soft/squishy if you don't, and that'll scare you if you need to make an emergency stop on 2 year old fluid. Fortunately, it's competitors usually only last a few months before requiring a flush, so this is a win. 2) It only has a shelf life of 2 years. Buy when you need it, don't buy it if you're just gonna put it on the shelf for 6~8 months. I've bought this stuff 5 (soon to be 6) times and they're usually 1 year old already from the date on the bottom of the bottle.

Amazing brake fluid & worth the cost
Used this in my 1199S which has a nasty problem of developing air in the clutch line (yes, ducati still uses hydraulic fluid for their clutch) which results in bleeding every 500-800 miles. Sure, its quick but nothing gets you out of the riding mood faster than having to remove your gear, break out the tools and then bleed the clutch so you can get home without struggling to shift! Enter SRF Brake Fluid: I tried this as it is the only brake fluid that I'm aware of with the highest WET boiling point. Its nearly triple that of the other name brand fluids I used, including the famous 'B' brand. After I fully flushed my clutch with SRF, I have not had to bleed my clutch for 2,000 miles plus. The only cons are its price and that it has a short life span once used. I will reflush every 6-8 months although they say its good for up to 1 year. I'm glad this product exists as its diffidently a quality product that lives up to its specs. Yes, I also flushed my brake system with SRF and I have not lost any brake fluid since I've used it and, unlike previous fluids that would over heat and turn black by now, SRF is still its pristine piss yellow. I've not experienced any fading at all and the feel at the lever is amazing. This is now the ONLY brake fluid I'll use on all of my ducati's.

Best brake fluid money can buy, decent price if you cant find it local
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.

The only brake fluid you should use
If you know you know. This is the best stuff on the market for heat tolerance and dependable brakes.

Worth every penny for track use
Been running SRF for a couple seasons now and it holds up better than anything else I've tried under hard braking at the track. Pedal stays firm and consistent even after back to back hot laps which is exactly what you need when you're pushing hard. Yes it's expensive but when your brakes matter this is not the place to cut corners.

Long lasting, great high temp resistance, recovers after abuse.
I used this on my race cars after chasing brake fluids for years. There's a reason all the high $ Porsches were using this fluid. If you happen to abuse the brakes and overheat the fluid this fluid recovers when other racing fluids don't (regardless of their temperature rating). You'll have an ever so slightly softer brake pedal feel, but this stuff is what you want. I retired from racing as a hobby and now use this fluid in my SUVs. It's worth it. Don't compromise your braking performance.

Buen líquido para uso exigente
Uso este líquido de frenos desde hace años. Es un líquido de alta resistencia térmica ideal para uso exigente, con mucho calor o en circuito. Es bastante caro pero da buenos resultados. Para un uso normal o solo en carretera no lo recomendaría por el precio. Si tienes problemas de sobrecalentamiento de frenos y tu líquido se pone oscuro en poco tiempo, entonces si, merece la pena. Con 1L tienes para cambiarlo varias veces o en varias motos.

Vale quello che costa
Da possessore di una Ducati Multistrada 1200 del 2011 è l'unico olio che sembra riuscire a ritardare il problema ben noto della formazione di aria nel circuito del freno posteriore. Prima ero costretto a fare lo spurgo ogni anno mentre con questo dopo due anni ancora nessun problema.

Great stuff
Pretty sure this is the best brake fluid money can buy. You shouldn’t mix this with normal brake fluid, so make sure to use the entire 1l to properly flush your old fluid out.
