Captured Moons, How the heck do planets capture moons> Options

[Chmee]

A question that has bugged me for a long time is how planets capture asteroids, etc into an orbit. My understanding of orbital dynamics is that a body approaching a planet would need to be "braked" in order to be captured into orbit. In the same manner that our space probes use their rockets to slow them down enough or they would shoot past.

So for moons like Triton, Deimos, and Phobos (as well as the small, distant moons of Jupiter/Saturn) how were they captured? What provided the braking?

Gravity is certainly the answer here...
The large planet Jupiter (gas giant in some way a failed star) acts as a vacuum cleaner and sucks in matter that comes to close (remember 1994... Shoemaeker-Levy comet).
Pioneer 10 had a dust particle counter and when it closed in towards Jupiter, the particle count went X100
