My extended z axis 2006 does have a brake but most don’t.
Check inside your column if it does not have a counterweight it will have a brake. There is a little brake controller board in The electric cabinet.

Check you z axis give and especially the straps. They tend to wear a lot and never get checked.
I like to bring the head casting down on some wood and put a few thousands of preload to help take the weight and then just start tightening the strap (ccw on the 1/4 bolt) and if it hasn’t been checked in a while you’ll get a few turns out of it. I just did one the other day and got about 10 turns before the strap started touching.
