Castrol SRF Racing Brake Fluid - 1 Liter 12512

Fantastic brake fluid. When I decided to start to driving track days I did a lot of research on brake fluids and Castrol SRF was rated highly (along with Endless RF650), however the biggest sticking point that kept me looking at SRF was the longevity aspect. I'm able to keep this fluid in my car for up to 18 months (year and half) and as someone who uses their cars (Fiesta ST and Corvette C8 Stingray) for both daily driver and track use it made the most economical sense. It's DOT4 compliant which means it works with most vehicles ABS Systems, and has an extremely high wet boiling temp. Works just like regular brake fluid (albeit at a higher cost when compared to regular high-temp DOT4 fluids) but with the replacement frequency being lower I expect the cost to average out. I had no fluid boiling issues on track, and I was extremely hard on the brakes as an early-intermediate track driver. My pads and rotors took the brunt of the punishment but overall this was a fantastic brake fluid that I will continue to use for both my vehicles!

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.

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.

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.

If you want a high performance brake fluid that last and works excellent even after absorbing moisture, then this is the brake fluid you want! It’s expensive for a reason.

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.

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.

The real deal. Good price. Some of the best fluid you can get. Packed well

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.

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.

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.

Je connais bien le CastroL REACT SRF RACING c’est le meilleur , je recommande ce vendeur à tout le monde livraison ultra rapide , c’est le top! Merci.

It’s not cheap but what a difference to the rest !! Got this because the rear brake on the Ducati Multistrada 2011/12/13 are known for fading rear brake ….. use this and ya be a happy rider
