The brakes not holding is one thing, the car not being able to run up with a full load makes me wonder about the counterweights. Whats it counterweighted at? I wouldn't assume whoever installed it got the right amount of counterweight in it. I have a couple ecospaces where counterweights were either in the machine room or on the cartop when I picked the job up, seemed like someone just wanted to go home on a Friday and not fix it right.
