hydraulics
-
most of the cars nowsaday uses hydraulics system be it in the brakes or some other parts. i was wondering how do these cars operate in countries when the temperature falls below 0 degree celcius? if the water freezes it might cause some damage to the car like bursting the pipes.
do they change the fluid in the system to counter this problem? -
Hi lost soul,
Hydraulic system runs in mineral or synthetic oil, they do not run with h2o. water is a reactive agent for corrosion to hydraulic parts. These oils have lower freezing point due to the additives in the oil.

oh thanks for clearing it up, i dont know why i naturally associate hydraulics with water(h2o).

dey use incompressible liquids...Originally posted by l0st-s0ul:oh thanks for clearing it up, i dont know why i naturally associate hydraulics with water(h2o).

Simple, they don't run on water.
They use oil or synthetic fluids with viscosities that are not/very little affected by pressure or temperature change. -
