rear cylinder resleeve in melb?

[aircobra]

while i was going thru the rear end looking for the diff clunks, noticed that brake fluid all over the rear wheel cylinder. got a new set from zcardepot about 3 years ago, so pretty cheesed about the quality

anyways, i see that a replacement pair will cost me around $150-200 and I'm guessing that they all comes from the same generic factory in china . so, rather then go thru the same process again in 3 years, does anyone know who can resleeve the old ones in SS?

thank you

also, does anyone know how to plug the brakes lines while i'm getting these replaced? i know you can crimp the hoses with the vise grip, but is there a better way

like this?

I just use the tapered end of an artist's wooden handle paint brush jammed in to the disconnected hard line... low tech maybe it is, but also zero cost...
