I put new calipers on the front due to one hanging up on me. It happened at the beginning of fair week and there was no time to tear down, so I drove all week with it holding tight. This, in turn, warped the rotor. Pads were shot, already. All those parts were getting changed, regardless of this issue. I was merely making the point that I have what I believe to be well functioning parts on the front end, with exception of the possible hose. I am trying to avoid throwing parts at it, which is why I'm asking.
I should have described the term better. What I mean is that when I apply the brakes in a normal fashion, I don't notice much unusual movement at all. When I apply them quickly, such as for an emergency stop, the truck pulls to the right, but I don't notice significant movement in the steering wheel. Almost as if it is swinging from the rear, not turning. When I get off the pedal, it stops pulling and does not pull back the other way. No brake vibrations - smooth stopping, aside from pulling.
Tires are new, all same rating and shocks are probably the originals, so they're getting replaced soon. It was aligned this spring and still drives straight down the road. The issue only occurs when brakes are hit suddenly.
Actually, I didn't go into more detail, just because I thought it belonged in a different thread with another subject line. I was asking about the flapper situation because I've heard of it happening, but haven't, personally, experienced it as far as I know. I wondered if it was something that really occurs.
