brake fluid Options

[kamax]

can our car use synthetic brake fluid?

i am asking because i put it in my bakes and it feels really light. i bleed the system and all.. but the first press feels really light, and the brake pedal goes right to the floor with lil resistance.

Doesnt an air bubble just make the pedal "mushy" (rather than being firm)? If it goes all the way to the floor with little resistance, pedal droping with constant pressure that sounds like a master cylinder (or in my case, rotten hard lines)
eg.
stopped on a hill you need to keep pressing the pedal further and further down to stay still

You should be albe to press the pedal down, it will get firm and you cant press it and further.


As for synthetic fluid it doesnt absorb water, which is bad. (hydroscopic) Regular fluid can absorb small amounts of water (reduces boiling point) but it keeps water from sitting in your lines and rusting them out.
