On the Soyuz they deploy only in the event of the emergency when top two
sections of the Soyuz spacecraft with the crew have to be pulled off from
the third stage by its escape system. At the time they were designed in the
1960s, they were considered the simplest way to slowdown the failing vehicle
and allow safe separation between the two. Chinese purchased this design
from Russia, so they used it as is.

Are they used during flight or only in the event of the firing of the
escape rocket?

And why are they needed at all?  The US does not use them, neither does
