Brick producer limits time to fire (3,2)
I believe the answer is:
let go
'fire' is the definition.
(I've seen this in another clue)
'brick producer limits time' is the wordplay.
'brick producer' becomes 'lego' (I am not sure about this - if you are sure you should believe this answer much more).
'limits' is an insertion indicator (limit can mean to contain or block off).
'time' becomes 't' (abbreviation).
'lego' going around 't' is 'LET GO'.
'to' is the link.
Can you help me to learn more?
(Other definitions for let go that I've seen before include "Discuss no further - dismiss - release" , "Relinquish one's grip" , "sack" , "Drop" , "Dismiss (from ones thoughts?)" .)
