Front end gets shaky...

[Jabes1]

I've been DD'ing my truck recently, getting the bugs out and I've ran across an issue with the front end. It seems to be intermittent. Some times Ill get on the brakes and the front end will shake.

I checked the wheel bearings and replaced them for good measure and that didn't help. I have a rebuild poly bushing kit for the front suspension, however I haven't installed it yet. I was thinking warped rotor, however like I said it happens intermittently and not all the time. All the warped rotors I've experienced were never intermittent. I checked my brake fluid and it was shockingly low. I refilled it and bled the brakes. I don't have any obvious leaks from the brakes, but maybe one of the calipers is dragging and slowly weaping?

My power steering box is leaking at the seal so it makes it hard to diagnose since there is fluid coating the drivers side caliper and control arm. That's next on the list of things to fix. I hate leaks, but brakes are a priority.
