switched over from super blue to castrol srf and damn the whole bottle was almost gone after bleeding and getting as much of the super blue i could get out without cycling the ABS pump. should be good for all year without a brake bleed astleast. Was sad to see the liter go so quickly

With SRF if you are hard on the brakes then you will have to do some brake bleeds to get rid of the boiled fluid that is in the caliper. Better order another bottle to keep around for this purpose.

I have been using SRF for about 10 years.. I have told friends about it and they now use it exclusively. It's worth the money.

Is it that much better than the Motul? Or is the major gain in being able to go longer between flushes?

Jaymz

The big difference between Motul and SRF is that SRF has a wet boiling point of 519 deg F and Motul is 420 deg F.

Dry boiling points don't really matter. Look at the wet number.

From what I remember the wet boil point is measured after one year and absorbing something like 3.5% moisture. So if you change your fluid often you'll never get into the wet temp. I totally flush mine in spring before the season starts then bleed just a little after each event to keep the dust out. There's usually always a little blacked fluid right at the caliper when I bleed them. At a brake tech seminar it was asked if SRF was worth the cost and the tech said no.

Here's a chart, note the progression from three to six months and then compare to the manufacturers wet rating (measured at one year).

For us the dry number is the only one that matters.

Depending on the track and if we are double dipping the car, we'll sometimes bleed the brakes at lunch and again at the end of the day to start fresh in the morning. And that was with Motul5.1 or Blue. Switched to Blue just because it was cheaper.

Well, yes and no. If you change it once a year then I agree, but the point is cheap fresh fluid is better than old SRF, Wilwood 600 plus etc. If you have the OE slide rail calipers, you should flush it before every event because there is only a few ml in the caliper with new pads, and it is easy to over cook it. I have never faded Wilwood 600 fluid, but it is not cheap either, like $20 a pint.

I agree, wet BP does not count for much if you flush many times per year.

Price matters though.

Try this.

A lot cheaper than hitting a wall when you brakes go to mush

dvandentop

LOL that is for sure

Jaymz

All I know is that I have tried to use cheaper fluid but the brakes allways seem to be spongy the last half of a race. When I have went back to SRF brakes last the whole race. I have good brakes, ducts, pads, etc.. The only difference was the fluid.

If you are Autoxing or time trialing for a couple laps then you can use a cheaper fluid but racing for a 30 minute sprint race you need to have good fluid.

I generally bleed the brakes before every weeekend the car is on the track.

Rumors are DRM hasn't changed their price yet on their website.

I had this exact discussion with Kurt at Phoenix tonight. In the long run, the SRF is less expensive due to it's higher boiling point.

He bleeds brakes after each session to check for burnt brake fluid. He only has to drain a very small amount of SRF compared to the lesser boiling point brake fluids.

With the lower boiling point fluids, you have to replace all the fluid in the caliper with freshto get maximum braking again.

Yes, the intial investment is higher but you use less and that makes it cheaper in the long run.

Danny Poop switched me to SRF and I will never go back.
Got 3 bottles in the shop and it is worth the money for bleeds etc.
