Not to hijack your post but I have a fairly similar question. I just replaced the clutch master, cdv delete, slave cyclinder, and clutch. I also want to totally flush the clutch / brake system. Does it matter which system I do first? I figured if I flush the brakes first them it should mostly only be new fluid in the clutch system because it's all new and has no fluid in it currently. As opposed to starting with the clutch and sucking the old fluid that is currently in the reservoir into the clutch system. Thanks for any help.
