Default How much brake fluid reqd for a flush?

I'm going to be changing the brake fluid in my Crossfire this weekend and I see in the manual that it states .5L capacity. I'm thinking that is the reservoir capacity correct? How much fluid will I need to have on hand to do all of the lines and refill the reservoir? I'm going to have to order it online since no one local has what I want to use (ATE).

Thanks.

Two liters should easily be enough, but I'd go with three just to be safe.

I never flush.. I use Dot 5. It's permanent..Used it since 1978 in all my cars/bikes. No rust or leaks. gary

I just flushed and changed mine a few weeks ago using one of those vacuum pump devices and only ended up using about 0.5L.
I replaced mine with Ate Super Blue. Everything in the reservoir is blue as well as what comes out when you bleed it, so that should be the whole system...?

^^^ agreed! I bought 3 liters a couple of years ago to do mine and used a little over half a liter... I am still good for a few more fluses.....

NOTHING is permanent.... brake fluid especially... it should be changed at least every couple of years....

(not trying to start a heated discussion, so lets just call that my opinion)

Can you even use Dot 5 in our cars? I thought it was a no go with our ABS and stability control systems.

I thought so, but would be very worried about a complete flush during the swap over because it does NOT mix with dot4...

Dot 5 eats some seal materials and as stated by Boiler will not mix with DOT 3 and 4 fluids as it forms clots of sludge. Flushing will leave pockets of DOT 4 behind and that can't be good.

Any water that got into the DOT 5 system by some freakish manner remains as water and will corrode the metal, freeze and boil.

Manual says DOT 4 and that's good enough for me.

No discussion. Google Dot 5 and read. It's in my Norton since 1978. as sweet and clean as when installed. Gary

Required brake fluid is DOT 4+......and yes there is a difference

I put Dot 5 in my old 280C Mercedes and it cost me a slave cylinder. I didn't get all the old fluid out and I won't try it again.

I've put gallons of dot 4 fluid through my Crossfire with all the track days and complete renewals every year. (Motul) It takes a little less than a liter unless you can't tell when the new stuff is coming out.

Motul RBF 600, good enough for me.
From the shop manual;
"Use brake fluid approved to MB 331.0, such as Mopar part number 0454925AC, or a DOT 4 brake fluid with: minimumdry boiling point (ERBP) 500°F, minimum wet boiling point (WERBP) 356°F, maximum viscosity 1500 mm2/s, conforming to FMVSS 116 and ISO 4925."


•ERBP - Dry equilibrium reflux boiling point - the boiling

point of new, freshly-opened unused fluid
•WERBP - the boiling point of a brake fluid after it has
absorbed three percent water.

The things you learn here that before getting a Crossfire you never cared a rats a$$ about.

Googled as suggested.
DOT 5 should be changed more often than DOT 4 fluid according to this article.
Silicone Brake Fluids
In years past, all brake fluids were glycol. Then D.O.T. 5, a silicone fluid having a higher temperature rating, emerged, initially to meet the higher boiling point requirements of racing use. (Race car brake systems include oil-cooler-like heat exchangers and ceramic pads.) Silicone fluid was able to withstand the most heat of any brake fluid, so it earned a reputation as a racing brake fluid. However, silicone brake fluid has properties very different from glycol fluid, and has its own pros and cons. On the advantage side, silicone fluid will not harm paint or plastic, and does not aggressively attract additional moisture as glycol fluid does. On the disadvantage side however, silicone fluid aerates easily. Harley-Davison, one of the sole current OEM users of silicone fluid, warns buyers to let the fluid sit at least an hour before using it. The trip home in the saddlebag is enough to aerate silicone brake fluid until it looks like a freshly poured soft drink. Silicone fluid is also slightly more compressible than glycol fluid, does not change color to tip the user to its moisture content, and worst of all, neither accepts or disperses moisture, making systems using it more corrosion prone, and requiring much more frequent fluid changes. Silicone brake fluid also lacks glycol fluid's naturally occuring lubricity, making it incompatible with the mechanical valving in some antilock braking systems.

To type the degree symbol.
Using the number keys on the right hand side of the keyboard while holding down the Alt key type 0176. Thus °.

From wiki.
The Kelvin scale is named after the Belfast-born, Glasgow University engineer and physicist William Thomson, 1st Baron Kelvin (1824–1907), who wrote of the need for an "absolute thermometric scale". Unlike the degree Fahrenheit and degree Celsius, the kelvin is not referred to or typeset as a degree. The kelvin is the primary unit of measurement in the physical sciences, but is often used in conjunction with the degree Celsius, which has the same magnitude. Subtracting 273.16 K from the triple point of water (0.01 °C) makes absolute zero (0 K) equivalent to −273.15 °C (−459.67 °F).

Thanks everyone.

I'll be ordering either ATE Super Blue or SL.6, haven't decided which yet. I'll be running the car in a couple track days a season but mostly just driving around on nice days.
