One gets worn down when stopping in talked about holiday accommodation (5,3)
I believe the answer is:
brake pad
'one gets worn down when stopping' is the definition.
'talked about holiday accommodation' is the wordplay.
'talked about' indicates a 'sounds like' (homophone) clue.
'holiday' becomes 'break' (I've seen this before).
'accommodation' becomes 'pad' (I've seen this in other clues).
'break' is a homophone of 'brake'.
'brake'+'pad'='BRAKE PAD'
'in' is the link.
(Other definitions for brake pad that I've seen before include "slower?" , "Stopper" , "it can cause friction" , "One applies friction in a car" , "it helps to slow down" .)
