Check the sticky at the top of discussion page for suppliers of parts. Florin is one of the most popular.
But considering where you are genuine Cat may be as cheap as after market when shipping is included.
I see on M.T. that Don Clark Tractors Sydney have 1 Set [02-84172928 ] Tilly's Toowoomba should have them ,[07-46336000 ] also ,Personally I would Go Genuine usually longer Lasting than Non Genuine , It's not the easiest Job , and Cat should have them in stock . Where in Aust. are You Located ? LJ
I just looked at the Cat Dealer parts website here in Oz and 5H2307 is not a good number, my D7 3T 20000-Up Parts Book shows the brake kit as 7F7591 but even that doesn't show on the parts search which is odd, I would have assumed those linings would be in stock. Try and use genuine Cat parts if you can, I put a new non Cat lining on one side of my RD6 from a brake and clutch shop in Bendigo and while it brakes OK, it sqwarks something shocking every time and drives me nuts.

For 3T1-10730, set for one tractor is 3F6633 or two of 5H2309, also fits 7M, 4R1-3633, 9U1-3531, etc.
For 3T10731- up, set for one tractor is 7F7591, or two of 5H2307, also fits 17A1-19442, 10A1-1616, 9U3532-Up, etc.
I run two D7-3T dozers. One engine number is 3T21612, frame number unknown as the control winch (25) and ripper are covering it which requires the linings. The other is dozer is engine number 3T16017, frame number 3T17311. After checking both parts books, the linings are different, thanks Josh. The lining kit I require is 5H2307 for serial numbers 3T20000 to 3T23646. The parts book is a bit misunderstanding as it states 5H2307-Lining group_2 each consisting of complete set of linings & rivets for one brake. Is this part number one or two lining sets. I will go to Westrac Caterpillar and try to get genuine parts if possible.
5H2307-Lining group is for one brake, you need two of that part number to do both brakes. From 657cat's post, you might have to buy the parts individually from Cat, if no longer available as a set.
