they usually work using hydrolics. You need to drive the car onto most of them.
Hydrolics and all things that run off of Hydrolics
yes, fluid is required to work the hydrolics in the gearbox
hydrolics work on high pressure fluid pushing pistons up or down. a hydrolic arm that goes up will probably work on a lever with the arm on one side and the piston on the other side that goes down, and the piston is powered by pressurized fluid pushing the piston down.
you just spelled it
By Hydrolics pushes up down side to side
hydrolics... I think
if it has hydrolics there should be a system in the car to raise it and if you dont you would need to purchase hydrolics to raise it to your ideal height.
replace rear brake hydrolics
The pump or other hydrolics will break.
