Free use of Braille (7)

I believe the answer is:

liberal

'free' is the definition.
(I know that free can be written as liberal)

'use of braille' is the wordplay.
'use of' is an anagram indicator.
'braille' is an anagram of 'LIBERAL'.

(Other definitions for liberal that I've seen before include "Generous, like a British political party" , "enlightened" , "Giving generously" , "Lavish" , "Progressive -- open-handed" .)

I've seen this clue in the Evening Standard.
