Entry Step problem

Entry Step problem
I suspect this is the case. My step neither fully extends nor fully retracts (intermittently) in cold/snow weather. Above freezing, it tends to work. Unfortunately, the in between state makes the step somewhat treacherous when you step on it as it will swing underfoot unless you step very directly with no lateral force.
Unfortunately, the pattern is not consistent enough to create a reasonable theory of the flaw.
As for Brad's step, because it extends, retracts, and extends again, I wonder if there's an electrical connection in the control circuit that's at fault?

Entry Step problem
Pete, have a close look at your lock out mechanism. Mechanically, the way mine is designed the fork on the end of the actuator is attached to the step extension arm and when it is extended the mechanism at the point of attachment goes over center. (ie. like bending your elbow backwards if you were double jointed.) This can be adjusted by screwing the fork in and out and locking the fork in position in via lock nut, at least on my bus.
If air pressure is low and the step rotation points are not properly constantly lubricated, the step will not lock out.
Typically, I use the extend switch when I enter a park and leave the step out. When I leave, I put it back in. Mine works when the door opens and closes but if the air is low, the lock out mechanism allows the step to float allowing one to bust their #@!.

Time for another 'rest' under the bus... 
The extend switch normally causes the step to remain out (and locked) so long as the ignition switch is off. If there's not enough air, then it stays extended. I understand the overcenter status -- I've pulled the stair out by hand a couple of times, locking it in the extended position.
I'll examine to see if there's something out of adjustment and ensure that everything is well lubricated.

Entry Step problem
Pete,

I've had the same situation with my step. Nearly lost my buddies wife
one cold night. It only happens when it's below 40 degrees or so.
I've also had the thump noise from brakeing but it seems to have
cleared up after it got lubed on the last chassie servicing. Perhaps
the fix for the other coaches may be a little greese.
