sliding pin stuck in torque member

[OBX Frontier]

Was planning on replacing a hub today, but the bolts to my torque member are so rusted on, I'm going to take it to the shop to have it fixed. I tried PB, WD-40, torch, everything, no breaking them loose. Hard to get any leverage in that little area. Long story short, I figured while I was under there, I'd change my brake pads. I'd also noticed the right front wheel pads were sticking a little. Well, after finishing up the driver side, I moved to the passenger side. New pads on, and I'm sliding the calliper on, but it won't go. The lower sliding pin is seized up. It won't move to fit the calliper on. I can put a wrench on it and turn it, but not easily. I think the grease dried up. I figured I would pull it out, clean it, and grease it up. But for the life of me, I can't get it out. I spun it like crazy w/ an impact wrench hoping that would loosen it up, but still nothing. It's nice to know why the brake was sticking, but really frustrating not being able to fix it. Is it possible a vacuum has formed behind the pin in the torque member preventing me from pulling it out? I'm sure someone has run into this before, any solutions or suggestions? Thanks.

Well, I got it fixed. I had to take the torque member off to make working it out easier. Then I had to drill a hole at the base of the hole the sliding pin goes in. Squirted a bunch of WD-40 into it. Ran a bolt w/ a fender washer behind it down into the pin where the calliper bolt would normally go until it bottomed out. Had one of us at the bolt w/ a power drill and foot through the torque member on the floor. I put the "crotch" of a huge pair of bolt cutters behind the washer, and pried up while the drill spun full speed. Popped right out. I noticed the bottom pin has a rubber sleeve on it, unlike the top one. There was a good amount of rust in the hole. Cleaned it all out, epoxied the drill hole, let it set, then greased it up and now all back together.

Good stuff. Next time take the part of the caliper with the pins off. put the pin (the head of the pin) in a vise and rotate it. Spray whatever you got handy. While still in the vise hammer downward. It'll come. Just did another Sentra (2nd one in two months) and used this method. I can atest that yes those are a bugger to get out once the lube has dried up. New pins are cheap and available at most parts places for about $15 a wheel.
