Steering got really hard on occasion when turning right. But I found the problem.
I had some speaker wire that was too close to the steering wheel rod, and it got caught up in there, and was causing it to be tight. The wire finally gave and the steering went nice again. did some hard braking tests, and all and the problem hasn't come back. I rerouted the wires away form the steering bar.
But it did exhibit a symptom of being very tight on a right hand turn only occasionally.
Thank god I figured that one out, I inspected the caliper and everything, all looks good, brake fluid is fresh, and it appears to be ok now.
so Luckily I think the problem was the wire that got wrapped around the steering rod.
