I'm a little stuck... Click here to teach me more about this clue!

'putting your foot down hard on' is the definition.
I can't judge whether this definition defines the answer.

'back mats top paving in first garage' is the wordplay.
'back' says the letters should be written backwards.
'top' suggests taking the first letters (in a down clue, the first letter is top).
'first garage' becomes 'g' (1st letter of 'garage').
The first letter of 'paving' is 'p'.
'mats' reversed gives 'stam'.
'stam'+'p'+'in'+'g'='STAMPING'

'the' acts as a link.

Can you help me to learn more?

(Another definition for stamping that I've seen is " Walking noisily or angrily".)

I've seen this clue in the Sydney Morning Herald.
