Brake fluid leak from caliper

But the seal on a bleeder to caliper is a tapered seat so unless the seat is getting distorted which would be incredibly hard to do then even if the thread fit got looser the bleeder would have to physically back out for it to leak. Just doesn't add up.

The heat is traveling from the pistons, straight up to the bleeder area. If the bleeder area was about 1/4" higher or had more meat to the outside of it. We might not be talking about this.
