Remove old brake fluid or bleed it through?

[M@tt_182]

I'm planning on changing my brake fluid for some ATE super blue however what's the best way to remove the old stuff? I'll be using a Gunson Eezibleed kit for reference.

You can't just remove and replace. Needs to be bled through. Do not let system run dry, make sure the reservoir is kept topped up.

The only way is to bleed it through. You can remove a little from the master cylinder with a turkey baster if its particularly full.

Thanks for the quick response, it's what I thought but I read some threads that made me question it! I imagine 1ltr will also be enough for the whole system?

Yeah 1l will be enough. I think the systems half a liter but you will need the full liter to bleed it through.

 

[DannyR]

Only need 500ml to bleed through but get a 1l bottle.

Ok great, would you also say its worth changing the lines for braided ones at the same time?

 

[MartinR]

Yep braided lines are well worth it.

When fitting them do I have to be careful to keep fluid in the system? I read about getting air in the ABS system which sounds worrying!

Just dont let the master cylinder get low and you'll be fine.

 

[MartinR]

When i changed my lines i hardly lost any fluid. But as mentioned don't let the fluid run low.
