I went over to my local autoparts store today and they had no idea what I was talking about when I asked for a locknut wrench for screwing a Honda brake caliper piston back in. Didn't see anything on the shelf, either. Is the item linked below what I'm looking for? http://www.sears.com/sr/javasr/product.do?pid=00946344000 Also, is there an equivalent to the Brake Spring Compressor tool, part #07HAE-SG00100, that might run less than somewhere other than slhonda.com? I'm debating whether to disassemble the caliper to see if I can determine what's failing in the caliper piston adjustment system, or just replace the whole thing (assuming screwing the piston back in, as Randolph suggested, doesn't fix it). But by the time I buy the spring compressor tool, a pair of snapring pliers, the various replacement parts, and spend the time disassembling/reassembling the sucker (and it's now getting cold here and I have no indoor garage!)... well...
