About quality and texture - The whole tool is made of quite thin materials and feels undersized. For example, the handle has square edges and even with the covering it hurts to hold this tight in your hand and turn it. I found that I needed to hold it tight before turning as the lock screw is very thin (M3 size?) and if felt that if I tightened it too tight i would just cross thread it or round it off, although the folded steel bracket that holds this screw bends when you tighten as well so maybe its poor design (only held on one side) would stop that? About the feeling of use - It hurts to use this tool on an old caliper that needs a lot of pressure. I expect this would be ok on something that was in good condition, but on an old rusty caliper (with clean piston faces) this tool did not work. The (looks hardened as you can see in the photo) grips in the 'jaws' dug deep into the old piston inside edges and ripped the steel. Not something you would wish for if you wanted to keep those pistons. About Design - I think the deisgn is good but this set is cheaply made and I expect not the best example of the design. It is certainly not strong enough for being used on an old caliper where is piston is tight as that needs force to move it free, but I think that is probably the only reason DIY people like me would buy this tool. So, I have to say the design is 'bad' in this case.Cost performance and comparison with other products - It is cheap, but for my use it was money wasted. I didnt break it so I can at least use it on other (better) calipers, but it didnt do the job I wanted even when I heated the caliper. So I spent money on a tool and am no further forwards. There are other tools that look similar and I would look at those instead of this one.About shipping and packaging - shipping was fast and it was well packed.Any concerns, cautions, or advice when purchasing - I would not purchase this tool again and I suggest any potential buyer looks for another version that is built much more strongly if they are trying to work on old calipers.

I purchased this for CaliperOverhaul.
It will be a dedicated tool for that purpose, so there is no other use for it. If you are going to borrow it from another source, it would be better to do so.
Now, I don't have such a reliable friend, and the choice was to pay a Motorcycle shop to do it for a high labor charge or to do it myself, and then TotalCost becomes an issue.
How much would it cost to get the tools myself? If it costs nearly 100,000 yen just to get the tools, I would not hesitate to ask a Motorcycle shop to help me. I think I can do it. Thanks to finding this product, which is very cost-effective, I have decided to do it by myself.
By doing it yourself, you can take your time to clean and check. This time is fun. Of course, self-responsibility is the primary requirement. Prepare well and find someone to talk to if you think it is not going to work.
You had not yet given me any feedback on how you used it.
It is inexpensive, so it may be adequate, but the grip is so thin that removing a lot of pistons hurts my hands. Wrapping a tubular sponge or rubber around it will improve the pain. Also, if the piston diameter is small, the grip width is large, so it is hard to handle.
But it was cheap, so I am satisfied.

This was the first time I rode Brake's Piston, and I was pleased with how easy it was to use. However, since I have an air compressor, I don't think I needed it.
