So far, it works well and is leak-proof.

Leak from factory I ordered this brake caliper because my old ones (also Shimano Deore) had developed a leak... oily brake pads etc... quite a mess. Unfortunately, one of the two calipers arrived from the factory already leaking. When testing the brake, small air bubbles were immediately visible at the seam between the two halves of the caliper. I wonder if this wouldn't be noticed during a pressure test at the Shimano factory. A brake with a leak would immediately lose pressure and should be rejected instead of being sent to the customer... sad! Galaxus support immediately offered a replacement - for the support, I would give 5 stars... in contrast to the product.
