I think you'll be fine if you just bleed enough through every nipple to ensure it's the new stuff.

it doesn't mater about being abs or not it is only to do with the boiling point of the fluid but i would suggest changing it all for one grade and not to mix them! Ale.
Sorry, you're wrong. DOT 5.1 was specifically designed for ABS brake systems. It also doesn't matter if you mix 5.1 with DOT 4 or DOT 3 as, they are all glycol based, as mentioned before.

Also, I don't think you can use DOT 5 in every braking system as, it reacts bady to some rubbers and pipe materials iirc. I think it was only used on old French cars or something along those lines ?!

However, if you're looking for a decent brake fluid, go for the one with the highest boiling point which, will most likely be a DOT 4 spec. Something like Motul RBF600 or there's a Delphi fluid that's pretty good.

If you're not confident in bleeding the brakes yourself, get someone who is to do it. Brakes are pretty important afterall !!
