What size is the torx nut that holds the pads in on a K18 brake

Just grabbed my Torx set and went to check my K18's and the answer seems to be; a 3mm Allen key!

Pad nut is 3mm Allen/Hex. (Torx on the hose/bleed nut is T10 and the big Torx on the right is T30).

Thanks T, I must have an older version deffo a torx head

Mine's deffo allen key. Not sure what size torx it'd be.
Never seen white K18's either (thought K18 were black, K24 were white 😕 )

My k18's are white and as soon as my boss does one to the loo, I'll check if they're torx or allen key.

Ah good question – I've lost my Torx key for my K24s which I bought especially – can't remember the size but T25 is ringing a bell

T15 on them in the end. Now how do I fix a seized piston, I've tried brake fluid, release oil etc around it
