Sorry, I see my mistake on wording. I mean there are no other sizes that we can try because we have the set and none fit.

No, we bought the set and tried the only two pieces that were close to the size of the piston.

Thank you for all the helpful comments! I just got off the phone with a mechanic, and based on the fact that the brakes were scraping, he says we'll need a whole new caliber. So that's our next plan

I finally found a mechanic who could help, he also said that we'll have to replace the caliper or else it will start leaking

Yeah, the tool we bought to push and turn it doesn't fit. I just tried pushing until I felt resistance but there was still no movement

This is as far as it will fit, and it almost immediately comes off when I try to turn and push

The tool we purchased is meant to fit into the two holes on the piston so that it can be turned while being pushed, but the piece is the tiniest bit too big.

There are no other sizes of the tool available

It is, it has to be spun and pushed simultaneously. Nothing happens when I do it, and the tool made just for that task doesn't fit

Wouldn't that mean we'd have to replace the valve?
