How much is needed to do a complete flush of old fluid to new? I am looking at KNS, and not really sure which fluid to go with. I do plan on doing track days, however I am new to tracking the car. What's the best choice?
Splatter said:If you are careful you can do it with one liter, When switching to a new brake fluid, I used a liter and a half to make sure it was flushed out completely. ATE blue was ok but for the track, really really like Castrol SRF. After a long track weekend, on monday morning the Castrol felt like new, the ATE felt tired and needed a bleeding.
Get 2, and drain the master cylinder reservoir out with a turkey baster or if you have one a vacuum oil drain setup. This saves on the amount you have to push through to clear the lines. The Castrol SRF is the best brake fluid out there, it absorbs the least moisture of all the high performance fluids and has the highest "wet" boiling point. You can leave it in for 6 months or more depending on how hard you run it. It costs more up front but is worth the peace of mind.Shaun12 said:So if I get one bottle of the SRF stuff, it should be more then enough to flush out the enitre brake system and replace it with new fluid?
