brake flush
 

how much fluid do i need to completly flush my brake system?

Re: brake flush
 

One quart should be enough for a flush.
I use Valvoline 3-4 full synthetic.

Re: brake flush
 

Agree with OT. Unless you are one of the 1 percent who actually do it ever 2 years I would use nearly all of the bottle since it is useless after opening anyways.

Re: brake flush
 

if you want to be sure you got a complete flush they sell colored fluid in several different colors. just be sure not to get dot 5 which is almost always colored.

I use the ATE Super Blue Racing Fluid, DOT4. Has a much higher wet and dry boiling point.

Boiling point minimum: 536 degrees F
Wet boiling point minimum: 388 degrees
Designed to last up to 3 years under normal highway driving conditions


It comes in the blue color. I alternate between this and the ATE TYP 200 Amber fluid (which has the identical specs) when flushing the brakes to see the color change at the calipers. That way I know all the fluid has been changed.

Re: brake flush
 

the reason why i'm asking is cause i looked at the fluid in the master cylinder and it looks all dark which if i'm not mistaken brake fluid is normally clear

Re: brake flush
 

Usually a very pale gold or pale amber. Something like diluted Miller Lite, not gin.

hmm weird the fluid i got for my clutch master cylinder it was clear

Re: brake flush
 

Most are more clear than amber.

Re: brake flush
 

Where is this available? I need to flush a system and would like to use this because of the different color. Thanks

Re: brake flush
 

Just so you know, the Valvoline synthetic 3&4 has a High Dry boiling point of 480°f
and a Minimum Wet Boiling Point of 311°f.

Stock is DOT 3;

Boiling point ranges [2]
Dry boiling point Wet boiling point
DOT 3 205 °C (401 °F) 140 °C (284 °F)
DOT 4 230 °C (446 °F) 155 °C (311 °F)
DOT 5 260 °C (500 °F) 180 °C (356 °F)
DOT 5.1 270 °C (518 °F) 190 °C (374 °F)

Re: brake flush
 

i used ate in all the track cars i built, never had someone boil it

Re: brake flush
 

Learned about this stuff from newsvx. he used to run his 97 SVX at Summit Point and VIR.

He has been known to wear out a brand new set of brake pads in one day. Tech inspection requires brake fluid be less than 6 months old, but is probably flushed more often than that.

Harry swears by this stuff. Now using it in his 92 pearlie for autocrossing and other track events.

I still flush mine yearly. I never approach the boiling point, but even the best stuff is hygroscopic (absorbs moisture).
