i seem to have an issue with my new lift, going up my locks are clicking 100% in sync all the way up. but when i go to lower it on the locks one side lowers down onto the locks before the other. i would say theirs almost an inch difference between when the one side hits the lock and then the other side finally hits. Ive played with the equalizer cables and it didn't seem to help. it seems to me since the locks are in sync going up the it has to be something with when the cylinders are lowering,what am i missing here? Also i got my pad height within 1/8" and i also bled my cylinders again but got no air out.

I have been fighting an issue with my rotary lift. I pull the release lever and sometimes the far side pull the lock back and sometime it does not. I have tried adjusting it by a 1/4 and it seems to work and then a few times later I need to block it open to get it to lower. I assume it is the cable stretch and my lack of patience. Hope this help. My locks are spring loaded and cable released also. They are not sync in any way on mine.

You played with the cables? They’re pretty obvious how they work. You can reduce 1 inch of slop to a half inch but you can’t dictate where the slop prefers to go. Personally I don’t have mine tight per se. Would rather hear 2 clicks than keep everything under constant strain. FWIW.
The hydraulics are not supposed to help it syncronize. On some lifts (without cables) they do, but not on a lift with cables.

Equalizer cables need adjustment.
I had the same issue, and correcting the equalizer cable tension corrected it. Works perfectly now..

Try bleeding the affected cylinder again. Had something similar after a few uses.

Which way? I've adjusted them every way imaginable with the same result.

As long as the difference is less than an inch from full lift to full return to the floor I don't see the big deal.

You didnt say the brand of lift, but most 2 post lifts have control mechanisms in the hydraulics to limit lowering speed of the cylinder. If debris get caught in it, one side will want to go down quicker than the other.

Could be, but mine only has one. If debris gets caught in it, it wouldn't have any effect on synchronization. There's a big distinction there in lift design. Some lifts are totally synchronized by fluid, and if that's your experience, it's a totally different situation.

its an atlas 10k. i did play with the lowering speed some but didnt seem to change things at all

Keep adjusting. I had the same issue with denial, but eventually, after studying how the cable tension adjustment addicted the way the lift works when lowering (and raising), I figured it out.
If the safety latches don’t click at exactly the same time when raising the lift, you haven’t finished adjusting cable tension properly, and the lowering will be problematic.

The issue lies in your equalizer cables. Pull the 2 front arms out and lay a level between them. Adjust the cables accordingly. When the arms are level, you've got what you want. If your locks don't hit at the same time, it's not a problem. In order for them to be exact, your post have to be at the exact same level. In other words, your garage floor may be unlevel a little from post to post therefore, the locks are not level with one another. If your vehicle starts off level and starts leaning as it goes up, you have a post out of plumb.
