Hey guys, once again, I'm going road racing for the 1st time this weekend,and I'm trying to get everything in good running shape before then.

I'm switching to HP+ pads, and going to do a fluid change as well, what is a good brand of fuild that will hold high temps, and not cost a fortune (and I can find locally preferably)

TIA.

 

hey RX7GSLSE,

I sent your stuff today. I am not sure on road racing but my boss runs a supercharged miata out there and belongs to the Motorsports Ranch. He runs AP dot 4 or 5 fluid?? You can get it over here by my work....Motorsports Sales. Ask for Francis(he) runs the joint and caters to road racers...he stocks alot of road racing stuff....little hole in the wall. You will have to look the phone # up but he is located on Floyd Circle(thats the road) right behind TI.

Have you tried those springs yet? Are you going to run them at the track this weekend?

 

I love Pennzoil semi-synthetic. Gold bottle. $5 for 32oz and has a very high dry AND WET boiling point.

Never had fade problems with this fluid! I use it in all my cars and in all my friends' cars.

 

Motul 600

Highest dry boiling point fluid I know of. Castrol makes a fluid that's close on the dry, but way higher wet than Motuls (something around 450* wet) boiling point

I want to say it's Castrol SRF, I forget.

Best to good enough, price no object.

Castrol SRF - $69 per liter
- dry boiling point, 590*F
- wet boiling point, 511*F!!!

Motul - $11.95 per pint
- dry boiling point, 594*F
- wet boiling point, 421*F

AP 600 - $17.95 per pint
- dry boiling point, 610*F
- wet boiling point, 410*F

Wilwood/Sierra/Ford HD/Performance Friction Z (which I believe to be all the same fluid) - $6.99 per pint
- dry boiling point, 570*F
- wet boiling point, 300*F

Ranking them by the volume of bottles I sell:
Motul
AP600
Castrol SRF
Wilwood/Sierra/etc.

If cost were no object, I would run the SRF all day. The Motul seems to provide the best bang for the buck, and may still be overkill for autocrossing and street. If that's your intended use, save the money and use the Wilwood/PFC.

 

What about the ford fluid? I forgot which one , Carrol Smith speaks highly about it.

 

for the HP type pad any DOT 4 brake fluid will work(use the racing fluid if using Hawk blues or equivalent) just bleed it well before an event. always use a fresh bottle and discard after the bottle has been open for about a month or so (best to use small containers) . brake fluid will pick up moisture from the air(yes even through a tightly closed lid). or just use it in your daily driver. I personally use the Wilwood fluid and flush and bleed the system regularly.

 

Be careful, because Ford has 2 or 3 different fluids, I believe. I think the Ford Heavy Duty may even be discontinued, and that is the only one you would want. I had heard that it's the same as the PFC Z fluid, but I don't know for sure.

 

WOW, the Castrol is expensive, especially comared to the others. 2.1 pints in a liter so the Castrol by volume is more than 3x more expensive than the Motul.

Guess I'll stick with getting some Motul

Anyone have any experience with a brake fluid called Ferodo?? The stuff is made in England.

 

Motul 600F is sold for $9.95 per 500 mL at Motive Products http://www.motiveproducts.com/

Castrol is expensive, but you can leave the fluid in for the entire season...

There's also ATE Super Blue and Gold...http://www.motiveproducts.com/ordernow_fluids.htm

Ferodo's good stuff...it's DOT 5.1...pretty high wet/dry boiling points, and priced similarly to Motul 600F/RBF 600...

 

I have found that Wilwood's fluid will cause my brakes to fade late in a National (45 mile) race. I use Motul 600 and have never experienced any fading.
