Brace favourites to get up and dance (3-4)
I believe the answer is:
two-step
'dance' is the definition.
(two-step is a kind of dance)
'brace favourites to get up' is the subsidiary indication.
'brace' becomes 'two' (I've seen this before).
'favourites' becomes 'pets' ('pet' can be a synonym of 'favourite').
'to get up' is a reversal indicator.
'pets' reversed gives 'step'.
'two'+'step'='twostep'
'and' is the link.
(Other definitions for two-step that I've seen before include "Old-time dance in duple time" , "Old time dance" , "Wet pots (anag.)" , "Ballroom dance in march or polka time" , "Gliding dance" .)
