If you really want to go through your rear calipers frm "top-to-bottom" you'll need this rear handbrake arm seal kit. We're one of the only shops in the country supplying these.
Occasionaly the seal around the rear handbrake arm (under the arm itself) can become either rusted to the arm or elongated and warped from using excess amounts of solvents on the calipers (don't go too crazy with the brake cleaner). When this happens you'll need to cut the welch plug and reseal your arm in the socket.
While I generally don't recommend the need for this in a standard rebuild (most often not needed and can be more expensive than a good core caliper itself), I can give you a simple test to help you determine if you need this kit:
With your caliper disassembled and the inner adjuster out and the handbrake arm spring off, move the arm. Does it move easily from one spot to the next or does it still feel "springy"? It should move easily from stop-to-stop and stay in the position you leave it in; if not, the original seal has basically rusted to the arm and is binding.
We've got them if you need them. This kit does one caliper.
