Prospeed RS683 Xtreme Performance Brake Fluid

Prospeed RS683 is a revolutionary new racing brake fluid that is suitable for Street cars and for full Racing Cars. Not only does it boast a 683° F dry boiling point -- the highest in the industry -- and an extremely high wet boiling point of 439° F, but the innovative new manufacturing process actually makes this fluid more incompressible than other fluids! This means you can brake deeper, harder and longer!

Dissolved air & CompressionFree™ Technology
Brake fluid is a mixture of several different ingredients. Conventional mixing traps tiny, dissolved bubbles of air inside the fluid. Fresh brake fluid typically contains as much as 5% dissolved air. Air is more compressible under pressure than fluid, so this air leads to a soft pedal feel, even with fresh, brand-new fluid.

Prospeed's patented manufacturing process minimizes the amount of air that gets into the fluid during manufacture. Instead of 5% air, RS683 contains less than 1% dissolved air! This results in a very incompressible fluid for the firmest pedal feel and most predictable braking you will ever experience.

Save Time and money & Increased seal life!
Start with less air in the brake fluid and the fluid can last a longer time in the system. Instead of spending time at the track bleeding brakes, you spend your time driving and discovering other performance benefits. Recent testing by Andretti Autosport has also found Prospeed RS683 to extend the life of caliper seals by 30% over the (former) leading IndyCar brake fluid!

Prospeed RS683 Specifications:
- Dry boiling point - 683.2 °F
- Wet boiling point - 439° F
- Vapor density (air = 1) - 10
- Vapor pressure <0.01 mmHg @ 68° F
- Density - 1.095
- pH - 7.2
- Kinematic viscosity 2mm2/s @ 212° F
- Freezing point < -74° F
- Compatible with all Dot 3, 4, and 5.1 non-silicone fluids, but full system should be flushed for maximum performance.

Testimonial Support:
- 7 of the Top 10 finishing positions in Continental Tire Races at Daytona 2012 use Prospeed RS683 Brake Fluid
- Several Daytona Prototypes (including the pole setter) use Prospeed RS683 Brake Fluid
- "That's some awesome stuff!" - Will, American Iron Champion, NASA-SE Div
- "I have been using RS683 for about a year now and have been very impressed with it." - Chad, Porsche Race Car

What does all this mean?
You can brake deeper, harder and longer, and be extremely predictable.

Looks like a nice mid-way between ATE/MOTUL ($15) and the Castrol($70).

Though notice that this is a half liter (16.9oz) bottle. ATE and Castrol are sold by the liter (33.8oz). This Prospeed fluid has a higher dry BP but a lower wet than SRF.

I noticed the huge drop off between dry and wet as well. You're going to be bleeding this fluid a lot. Here's a column I did on brake fluid a few months ago.

Let's see --

>> If I brake deeper, I BETTER NOT be braking longer!
>> If I brake harder, I will not need to brake longer.
>> If I brake longer, I can not brake deeper, and shall not need to brake harder.

I am certain this is a great product -- it just sounds very complicated to use.

I agree, I have been ok with Wilwood 570/600 for years and I like to bleed often anyway. I don't see how I could put srf in and leave it for a year like some say they do.

If I needed to I'd give this a try, seems that it has been around for a while. I wonder if one of the majors makes the blend for them or if they cook it up themselves?

is this silicone based fluid?

and can it be used in a system that may contain conventional fluid, or does everything need to be purged out

Here is what a technical race blog said about RS683...

"Why we feel this fluid is an acceptable substitute for Castrol SRF is that this fluid has an extremely low compressibility. SRF by nature of it’s design suffers from compressibility which is translated to the frequent “mushy pedal” you attain when driving your car at the limits. Silicone based brake fluids, like SRF are more compressible than conventional fluids due to dissolved air (16% +/-3%) which is inherent in all Silicone based fluids.

Prospeed is an Borate Ester based brake fluid which traditionally has a 5% (+/-2%) dissolved air content, but with a proprietary engineering process, Prospeed contains less than 1%. There is no other brake fluid in the market right now that has this low of dissolved air content and still attains the dry and wet boiling points Prospeed does."

Also, The less air you have in the fluid, the less steam you create when you overcook the fluid.

Ed,
No need to apply modus tollens logic or disjunctive syllogisms.
The fluid can accomplish either of the 3 benefits in the tagline.

Froggy, the Prospeed would enhance a firmer pedal, even if you like to bleed brakes often. I think the blending process is done outside the majors.


Prospeed RS683 is a Borate Ester fluid. And it is compatible.

Ah - "You can -EITHER- brake deeper -OR- harder -OR- longer -AND- be extremely predictable."

Got it!
