What brake fluid are you using in your hachi ?

Hi guy's
what brake fluid's are you using in your hachi ? and i also would like to ask how much do i need for brake system and clutch thanks

I use Ate DOT 4 oil, but a cheap DOT 5.1 is also nice.
Taking the bleeding procedure and some general sloppyness in account you should just get 1.5 liters.

i bought 1 litre and i still have almost half left. i have filled both the clutch and brakes. all bled.

There you go...I used up some more the first time I filled my system cause the brakes would not bleed the air out properly, and I rebuilt the calipers and master cilinder at 2 different occasions. 0.5 liters sounds about right, it takes the same amount on my volvo which is easy to bleed the brakesystem on.
I'm getting myself 4 new bleedvalves tomorrow so hopefully that will fix the problems with my brake system.

dot4 is cheaper than dot 5.1.. dot 5.1 is a full synthetic brake fluid..

i use Castrol dot 5 synthetic brake fluid..

I know DOT 4 is cheaper, but for street use I wouldnt exactly use expensive DOT5.1 oils...cheap ones work fine though..
Isnt synthetic DOT5 fluid bad for your brake system unless you flush it very often? If I remember correctly it isnt hygroscopic, so when water eventually gets into the brakesystem (and it will), it will stay together in one place and cause rusting brakelines..

i wouldnt put in dot5 for daily use.. maybe for trackdays, then replace it with dot4 or 5.1

Mintex racing oil. No DOT specifications. Say goodbye to boiled brake oil. I use it on the track and i'm very satisfied.
1l = 22€

DOT 5 is silicone-based and yes - not hygroscopic. But there is no way to find water in brake system - unless you fill your brake master cylinder reservoir with water :-) The only common problem with DOT 5 is uncompatibility with DOT 3, 4, 5.1.

If you will not find water in your brake system, then why does the usual brakefluid deteriorate due to water it absorbs?
