Nothing to do with leaky brake line joints anymore, but I use a 1/8" thick liner at the bottom of each tool drawer, followed by a 1/2" thick piece that's cut out to fit the tool using a very sharp hobby knife. IF I am afraid of slippage, I use 3M adhesive spray to glue them together. The socket drawers are the worst as far as patience, but if you take your time, you will really appreciate the time it saves in knowing whats there and whats not. I am sold on the idea myself.
