Brake Fluid

What's the best for every 2 year changes? Would like an upgrade? That Castro is too much at 80 per qt. Thanks

Unless you're tracking there's no need for two year changes. Get one of these to test it for water content, change it when you need to. https://www.amazon.com/dp/B0834PVSBT/ref=dp_cerb_2

If you are tracking ATE is well regarded. https://www.bimmerworld.com/Brakes/B...8aAhudEALw_wcB

Great little tester, especially for the price. My only concern is the potential need to consult with a Psychiatrist!

How much fluid will I need to flush the system an refill?

It's better to have extra fluid laying around that getting stuck half way your flush. And DOT 4 is commonly use on alot of cars.

Thanks for the link. I will order the tester. My car was telling me it was time so I reset it and didn’t bother to change it.

1L. You should have leftover too.

The car doesn't know if the fluid is good or not, so it goes by time only to tell you that it needs to be changed. When it did that to me after 36 months but only 12,000 miles I bought my tester, which confirmed that my water content was zero. Two years later it's still zero.
