 We're talking about more than 1,000 pounds of brake fluid pressure. You're never going to get that with air. Maybe 250 if you're super lucky and get a compressor that big, but not many around. Interesting. Yeah, you could try it, but I don't know if that thing is going to leak or not. They leak when they had those on airplanes. I mean, they were leakers. But that caliper, if you haven't touched it and it doesn't look like the threads are all ripped up in it, definitely get a hold of the company and say you want another one.
