Hey guys,

Quick question - looking to do a brake fluid flush on my 2021 IS300 F-Sport AWD to upgrade to some Motul RBF600. Any idea of what the capacity of the brake system is? Will I be ok with a single 500ML bottle, or will I need two?

Thanks!

 

To replace all the fluid I would get at least 2 bottles. Keep in mind this fluid LOVES moisture you'll need to change it more often.

 

Thanks for the reply. Will grab two bottles!

And fair enough on the moisture aspect. Just adding a little insurance for track work so it's something I'll have to live with.
