How does a micro lock work?

[Paul]

Does it take the place of a parking brake? How does it do whatever it does?

They are hydraulic, flip the lever step on the brake and they lock. Step on the brake again, flip the lever and they release.
However, you may roll 6" before the lock is complete... at least that is what happened to me in the mountains above Eagle River, AK on an icy road. After I lost it on a hill, spun a almost complete 180 and caught a small strip of sand before sliding off the road I went to use the MICO but I didn't have 6" to roll because I was about to slide my Ford tanker truck off the embankment and had already pushed three small trees over as I hung on the edge 6" and 1/2 mile from the next place I would stop in a heap. I had no option but to stand on the brake and wail on the horn until someone woke up at 2am to stuff a large rock under my rear duals until I could get another rig in there to pull me off the edge. And that's just where it'll get you thinkin' 'cause the road is sanded you don't need to chain up.... the last hill I needed to climb was where the sand ran out!
Most times a MICO is great and one is going in my Gladiator.
Another thing about them is that if you have the slightest hydraulic leak you will find out using the MICO.
