In the universe of Star Wars, many ships (excluding the X-Wing - the large circles on the front are retro thrust nozzles) appear to lack forward-facing thrusters or retro thrusters.
The TIE fighter has 2 engines, both which face backwards. So, what slows it down?
I read on Wookieepedia that they turn using etheric rudders, and read on a chat forum (I do not remember which) that they can use etheric friction to slow down, but I couldn't find any references to this. Do they perhaps use special repulsors to slow down? In this question many people answered that they use special repulsors to control their flight and direction, so perhaps could the same technology be used to slow them down?
So, how do Star Wars ships slow down?
To clarify, I want answers based on the Star Wars universe, not real-life physics. I am also willing to accept answers based on the Star Wars Extended Universe (now named Star Wars: Legends).
