Yes but don't use braid for the sinker leader or hook leader.
We used to use 18+half pound 'Tortue Supercontrol' mono for that style of fishing or 23+half pound if up higher. I personally only use braid for spinning and never rock work. You don't need that heavy a line, but if that's what you have by all means use it- wouldn't want to attempt breaking any snags with it though.
If you enjoy this style of fishing, save up for another outfit and put mono on it- you don't need heavier line than about 25lb (11kg) for just about any rock fishing bar live-baiting for big stuff.
My old line classes for the rocks were as follows- Bream and Luderick 3kg line on both sidecast and centrepin reels, Spinning lures 6,10 and 11.5kg (the latter only for Kingfish really) on all 3 types of reel (Spin, O/H and Alvey) Tailor/Salmon/Snapper 8 and 10kg, Drummer 6,10,15kg depending on area, Live baiting 10,15,18,25kg again area dependant. Cliff fishing 6kg for Bream, Luderick, 10-12kg for everything else- all mono, usually Tortue, Weiss(no longer available I think) or Schneider (it was cheaper but marginally thicker) all three brands were great for the rocks
