Brake Fluid Replacement

[CHRISK172+]

Anyone used one of those Gunsons Eezibleed Kits to replace there Brake Fluid? Fiitted my full set of braided lines today and replaced fluid with Castrol Super Dot 4. I read many people leave the rear lines but the worst part is the mess, otherwise pretty straight forward.
Regarding the Eezibleed Kit, I was wondering if there any issues with the ABS? The reason I ask is it seemed so easy and I haven't tested it as it's still on axle stands while I change my coilover suspension.

nowt wrong with them, but DO NOT EVER EVER EVER EVER EVER drain the system first and then refill it, always bleed it through

Any particular reason for that Fred??

Air pockets trap inside the lines so your brakes wont work properly i think.
Plus why do people not drain the back lines as well? I thought you would contaminate the new brake fluid when mixed with the old. Or am I reading this thread wrong ?

try getting air out of the abs pump and you'll see my point!
