Which Brake Fluid to use??

[Ant97GTR]

Hey Guys,

In prep. for the track day at Sandown next month I'm getting the brake fluid changed to a track ready spec so I don't boil it after a couple of laps :flamer:

For those of you (read: any Team Wang members )who have changed their brake fluid to a track ready type (higher boiling point) which readily available brake fluid would you recommend for a r33 gtst?? Just to note that the setup is std except for upgraded pads.

Also are there any compromises to using this fluid on the streets?

Thanks

I use the Castrol SRF. Its (apparently) the best - but will send you broke.

Most of the guys use the Motul Dot 5.1. The only adverse effect I know about high quality brake fluids is the lightening of the wallet effect. I stand to be corrected on this however.

[Ant97GTR]

Cool thanks Andrew. Do you (or anyone else) know how much fluid I need for a complete drain and change on a r33 gtst? Out of interest how much for the Castrol SRF?

[Snowman]

The castrol srf is $120 per bottle - and you will get 2 complete fluid changes from one bottle.

$120 holy cr-p

Thanks for all the info mate....for 120 bucks that fluid better do a better job than the std fluid around calder comp. circuit!! No-one said taking a car racing is cheap

lmao how will u know if it does a better job?

[Snowman]

Because after 2 laps your pedal will go to the floor with the standard fluid - especially at Sandown.

i seeeeeeeeeeeeeeeeee.

DOT 4 for the street as it's nice and cheap, but for track work definately DOT5, I've heard good things about the Castrol stuff too.

[inark]

does that mean once u have been on the track and go back to the street u have to drain it again???

[GTS-t VSPEC]

No, but it's damn expensive stuff, so you wouldn't want to waste it:D

[ylwgtr2]

it also has a shorter shelf life.....and i believe it is more likely to absorb moisture

[GTS-t VSPEC]

All brakefluids are hydroscopic (absorb water), but yes the DOT5's don't last as long, cause there meant to be changed fairly often.

[ylwgtr2]

i am aware of that

[Ant97GTR]

Thanks for all the info guys.....had my car at calder a couple of weekends ago at a driver training session.....the comp. circuit isn't very long or hard on brakes but by the end of the day I had to stick my foot through the pedal in order to wash off any speed. Not the best feeling when hoofing ur car round a track I figure that sandown is waaay harder on brakes so gotta get that fluid changed!

Sorry, wasn't trying to make out you didn't, was just for other people who didn't, as it wasn't that long ago when I found out:D

Yeh brake fluid is important, and i have no doubt that the Castrol stuff it top shelf, but i suspect most of use can make do with less.

I posted this before...

... i use AP Racing Formula DOT 5.1 Road/Competition Brake & Clutch Fluid. Part No. CP4510 , but may change to Motul RBF 600 whish i have heard good things about. Cheaper and still very effective is the Caltex GP 600 Racing Brake Fluid.

There are lots of guys running the Caltex up in Sydney as Race Brakes up there are now readily using it in all the street / track cars as they have been getting good results with it and it almost a third of the price of the AP stuff i use....from memory it cost $30 for 600ml .

Disregard above post....i need new fluid and pads before Sandown as well so just got some prices together.

The two parties i spoke to said dont bother with anyting other then Motul RBF600, which is $25 for 500ml. They are using in Stokell's Diablo and its working better then all the previous fluids. So good enough for me.

Also as far as pads go, (Prices are all form Race Brakes - Melb)

DS3000 are $385

Track only...save your road pads for the road and race pads for the track. They are actually easier on rotors with less grinsing when they are aup to temperature...so noise isnt the only reason not to use them on the street

DS2500 are $231

Road/track but as Snowman will tell you they aint exactly a great road pad.

RB74 are $160

What i have been using and have always been very happy with, Race Brakes still seem to think they will be up the job at Sandown given my cars weight power and tyres.

As my RB74s have about another 6-9 months of normal driving in them, im leaning towards the DS3000s (or the SAUWA - Hawks) for the track, since ill be changing wheels its only an extra 5 min per corner.

I am going to tack onto this thread and add...

Just got back from picking the car up from Meridian, top stuff in spending like 7 hours fitting the oil cooler to my beast!

I was initially going to get a set of Endless CC-R ceramic pads, but brent from nengun can't seem to source / get the parts... so... time is running out and I need to sort out my brakes.

Was talking to Toby at Meridian, and he was considering organising a group buy on braided lines (though prob not before Sandown).

Also, he uses an ATE brake fluid, one litre for like 50 bucks.

As for pads... thinking the RB74s might get a guernsey as a stop gap before I get these Endless pads. Does anyone think it is worth doing the DS2500s?

I have just fitted a set of ADR approved braided brake and clutch lines. I purchased these for $420 (brakes: front and rear) and $70 (clutch). The brakes are a two piece hose with a block in the middle, just like the originals, and bolt up in the original fittings. I have not yet felt the brakes as the car is still at the w/shop.
