I am planning to flush my brake fluid and clutch fluid. I run approximately 20 HPDE events per year - what fluid(s) do you guys recommend?

Castrol synthetic in anything other than all-out-racing applications........... then AP600 is my fluid of choice I'm sure the AP660 is good, but I've never tried it.

I swap between ATE super blue and amber.

J Ritt

We are a forum vendor and sell AP Racing fluids. I'd recommend the AP Racing Super 600. It is currently one of the most popular fluids in professional motorsports, it's competitively priced, it's on the shelf and ready to ship, and it's DOT compliant.

I still doing DE and I am not all that fast. I use Valvoline synthetic brake fluid and flush it before each weekend. Use in the clutch also. It has a fairly high dry boiling point and since I change it regularly I do not worry much about wet boiling point.

I'm with JRitt, AP is great, and a fraction of the cost of SRF.

Here's a good StopTech article with general info on fluids and down at the bottom a list of a few different fluids and their boiling points.

SRF the best by far. and if your doing 20 days the cost of fluid is squat.

Like dem Vettes

I use BG Super DOT 4 for brake and clutch. It's hard to find, though.

My problem with SRF is that if your calipers are getting hot enough to NEED it, then you really need to address your cooling system. A healthy brake system should last several weekends with any good fluid

John Shiels

but some never will adress cooling so it is better to have SRF and not find out after you need it. Even if you have cooling ducts it still is useful as my rotors will glow in the daylight. Granted I could buy a 15" rotor and race calipers but then I need all new wheels and the price tag is crazy.

naw!!!!!!!! it means your hauling *** and braking LAAAATE!

Yep....even with cooling, I'd rather run the SRF and have the highest wet boiloing point in the business. After needing to bleed/flush fluid because of breakdown/moisture, doing little bleeds is cheaper in the long run with SRF.
I see it as 'safer', too, and that makes me feel better...

I guess I'm the oddball. I like Motul RBF600.

rustyguns

check the WET boiling point of motul vs SRF itsssssssss HUGE!

gkmccready

Matches the price difference! As everybody else has pointed out, I bleed them so frequently that wet isn't really an issue...

ace996

That's the point of SRF...you don't need to push out so much when you do bleed. At the end of a season, most have spent less on the SRF than with Motul (what I used to use). And bleeding is not needed as often.

Eh...it's what one likes to do...change often with a cheaper fluid or keep a costlier fluid for longer. I like the SRF because I've never boiled it, even when I was less than attentive with bleeding.

I saved money switching to SRF.

me too
