Old school mechanics used to siphon out the brake fluid reservoir while performing a complete replacement of a vehicle’s brake fluid. It’s increasingly common for most vehicles to have a fine mesh screen in the reservoir though that’s very difficult to remove. While this makes it difficult to siphon the fluid from the reservoir, I think its not meant to be taken out, so I’ll leave it as is.

Question-
Is it alright not to siphon the old fluid from the reservoir, and just keep alternately bleeding and topping up until all the old fluid has been replaced while doing a flush?

-I know mas time consuming and magastos ito, because you’ll need to use more new brake fluid than “the old way”, but baka masira ko yung screen if I try to remove it.

-I also don’t have any “hi-tech” tools, so I won’t touch the ABS system either.

Any thoughts/input?
