Castrol SRF Brake FLuid??

I have to use this stuff in my car as everything else would boil at certain tracks. Now I am curious if I should flush what came in my Aprilia and use the Castrol SRF in the bike too.

My question is there anyone else who has used it in a bike? It's not the cheapest stuff at around $75.00 a liter but it works real well in my car.

 

As long as your bike uses Dot 3 or Dot 4, it'll work fine. If everything else boils in your car, you won't have any issues with it in your bike.

Expensive yes, but if you have to use it in your car and already have it, might as well put it in the bike too.

 

motul rbf600 ftw

 

can i have some of that please,
i just got me the $4.99 bottle.

 

Tried the MOTUL and had soft pedal after a few laps, the SRF keeps giving a solid pedal no matter how long I go. :hail:

 

If it works as good in my bike I'll save you the fluid when I drain it! :thumb:

 

This is the best IMHO

 

You're not riding a Suzuki, you'll be fine. Best stuff out there, IMO.

 

What he said^^^

 

Looking at some of the responses, I'll have to give this a try. I've been successfully using rbf600 for a while.

 

Motul RBF 660 - 617 dry boiling point.
Castrol SRF - 591 dry boiling point.

Long time RBF fan here.

 

SRF is what all the Triumph teams are using in the AMA.

You must flush the old fluid out thoroughly !

 

RBF600 is the only way to go for track use. No issues ever

 

I think Castrol has a higher wet boiling point which is more important for long life.

I used to used RBF 600 and 660 but gave up and use cheapo DOT 4 from Wal-Mart.

 

I do not pay it much attention. I make my little sister change the oil in all my bikes. I am not sure what type oil she uses.

 

When you say 'long life', are you saying you dont change your brake fluid after every track event ?

 

Castrol SRF has something in it that keeps moisture from getting into the system better than other brake fluids. Therefore you don't need to change it as often to get the best results. And yes the WET boiling point is the highest out there, which means in all reality normal conditions.

 

For the price one could change their fluid with Motul for every event and still be money ahead. Spectro and Bel-Ray have also given me satisfactory results, but I'm slow.

Remember that your bike weighs just a little less than your Viper.

 

i've had great feedback from motul rbf600 in both a gsxr600 and r6, don't see a reason to change.
