I haven't done brakes in a long, long time. However, looking at examples of the required tool, I see the same thing that I used for many years on my boat. It was used to open the flush deck plate fittings for fuel, water, and holding tank pump out. I had a couple of them that were adjustable like plyers with two different sized pins. I also had several that were relatively small with fixed pins. The small ones were aluminum and the larger was bronze. Perhaps one of the adjustable marine deck plate tools could be an answer for all brake pucks.....? Google "Marine adjustable deck plate tool" and look at the Sea Dog bronze Adjustable Deck Plate Key. Price I saw was $30.99..... Jim
