Locked brakes and power steering??

[csdineley]

Still having the power steering going out once and while. On my way to work, it went out once when I was turning onto a side street from a stop. But then worked fine the last mile to work. And on my way home worked all the way until I went to pull into my driveway. Both left hand turns. This pump I put back on is about a year old, belt about a month old. Any suggestions???
