The way you pressurise a cabin is simply explained as pump air into a tin can and control the rate at which you let it out. Nothing to do with the output pressure of an ACM.
Is it me or is that not a simple thing to understand.

RE: When Do Landing Gears Stop Spinning After Take Off

Metered Hyd pressure is fed to the brakes from the retract circuit and the nose wheels have spin brakes. Some aircraft such as A320 are not allowed to takeoff with brake temps of 300 +, a way of cooling on others is to prolong gear retraction. Option on some aircraft are brake fans.
