As subject my car is going in for a service tomorrow and I am having the brake fluid done as well, but I am not putting the standard fluid in. So I just wanted to put my mind at rest and make sure it will be OK. I will be putting some of the EBC Sport brake fluid in which is DOT 4 Glycol based. More info I take it the standard fluid is DOT 4 Glycol? and that it will be alright to just flush the system and put the new fluid in? Also do you have to flush the clutch master cylinder?
