I'm looking to get this but can't find a place in US. Does anyone know any place who sells this?

 

You try Roger Kraus in Castro Valley? They can order...

Opak told me that racing brake fluid is not worth it and is actually worse. Not just because of the DOT 5 vs DOT 5.1 crap. But shelf life issues for example: Motul RBF600 (per Opak) has a useable service life of 2 months for example. Great for a race car because you are flushing every race. But normal car is every year???

 

Opak is very wrong about this! I run RFB600 in my race car. I flush the brake fluid one a year, and after the flush I notice no diff. If brake fluid kept in a sealed container it will last for a VERY long time. The problem with brake fluid is that its hydroscopic. It will absorb moisture in the air and reduce it boiling point. (so once you have opened the container the boiling point will continue to lower)

 

I don't wanna ask why you are looking for this... Actually, I do. Not many even know this fluid exists, it has ~608 deg. boiling point, meant for severe track abuse or higher than normal track temps in certain applications. It's more appropriate to go with the Super 600 (~600 deg. boiling point). About 16.50 / .5L bottle (19.xx retail).

There is a new exclusive distributor for AP in the US. They happen to be local to CA and we happen to have access to the guy. So it's 'gettable'.

Interesting Anish,

Well ASM now carries this and they are putting those brake fluids in their customers car which hardly drive on the track. This made me think that may be I will try this brake fluids.

It is DOT4 approved so doubt that it would be really extreme use. Just like any other high performance brake fluids.

Let me know if you can get me I'll be interested.

 

Dot 5 is silicone.. This will help you out greatly to understand what I meant.. these are all considered racing fluids:



Brake Fluid is rated by dry boiling point (for fluid fresh out of the bottle) and wet boiling point (for fluid saturated with moisture). If you bleed brakes frequently, the dry boiling point is most important. If you do not change your brake fluid often, the wet boiling point becomes more important.

This stuff is a lil much for the street Hiro, and probably not worth the cost for your usage... Unless you are the track star Brian is with a dedicated car (who apparently can't keep from cracking even the best of 2pc rotors... )

 

Well, I know many of s2ki owners use MOTUL RBF600 and ATE Super Blue and compare to AP PRF660's boiling points, I don't see much of differences in numbers. If you say it's not necessary, none of those high performance brake fluids are not necessary.

I just wanted to know where to get and if anyone ever used it. It would be nice to know before I try it.

 

It's a bit overkill for street use, but I got your point... just want to make you aware of other things like the chemical makeup/stability, viscocity (which affects the temperature range it is intended for... IE our FSAE car's brakes were terrible when we took it out in 20*F Wisconsin weather for testing in January using AP 600 [Practically the PRF660 w/ lower wet bp].. we switched to Dot 3 Honda fluid I had until I picked up some AP 551 from Pegasus Racing the next day). But if you were to just glance at temps, they all look great. This is CA afterall.. you'll never see 20* out here. The cows would die if that happened. No beef for you...

Here's a place that should have what you were looking for in stock if you need it now. Stuff is expensive, if you have the patience, I can see if the local shop can order it. I have no idea what cost is on this..:

Safe Racer

I'll still luv you Hiro, whatever you do.

(I vote AP 551 for Street/Track and modern day Anish abuse use).

 

i vote for OEM BRAKE FLUID!!! everybody is using it!
