That's quite a high price for this little piece of metal. I have a set of rotary hammers that I used to knock pins out of the various Brembo calipers that we have on our cars. This one is much better because of the cupped ends. Unlike dies, this one won't slide off the page or chip paint. This is a very useful tool, wish it was longer. Or maybe two sizes. Helps to be longer to allow the pin to be pushed all the way through the caliper. Although a short length is good if you're driving the pin back from the inside, you'll have more wiggle room to maneuver the hammer. If you're willing to spend more for peace of mind, I think it's mostly worth it. Otherwise just use a punch.
