I have been researching past posts and they have been very helpful, however to clarify things a little, my hk has girling front calipers discs approx 12mm thick and I have two spare rotors and discs that are girlock and around 16mm thick, I take from previous posts that the latter are hg ht? and these would be better than the smaller brakes? Also where do i go in SA for new brake lines as the old ones are fairly rusty on outside?
Cheers

Jimmy64 i have recently upgraded the brakes on my HK Prem
to HQ discs and am more than stoked if you need to be pointed
in the right direction i can tell you what to do as i think i found every hiccup possible while trying the conversion. But well wort
