Dude, don't just throw parts at it.
Check the wheel cylinders.
It will be obvious if they are bad.
A slight bit of dampness IS ok.
If they are soaked, they are leaking.

How far out did you adjust them?
Ideally they should be adjusted out until you JUST hear the drum rub the shoes, then back off a notch or two.

Did you check/adjust the booster push rod to master cyl clearance?
There should be less than .5mm clearance.


The wheel cylinders are not even damp at all. I also adjusted them exactly the way you described. I havent checked the clearance between the booster push rod to the master cylinder yet. How would you go about doing that? It seems that as soon as you push the pedal down the brakes do start to hit the rotor so I dont know if that would be it. I looked up the part numbers for the GT calipers and ST calipers and they are different. And I think I may have gotten GT calipers when I replaced mine instead of ST calipers. Maybe the GT caliper takes more fluid to move the cylinders in them? I have had this problem after I changed the calipers but just assumed something else was wrong.

Are the caliper slides moving freely when you had it apart? Are both calipers holding when depressing the petel?

Well never mind the caliper slide on the passenger side wont budge at all. I've tried soaking it in pb blaster, tried to turn the pin bolt head to free it, broke a piece off of my c-clamp trying to push it in to free it (its stuck somewhere in the middle), and hitting it and its housing with a hammer. Any Ideas on how to get it unstuck. I was thinking ab heating the bracket up to try to get the hole to expand. I don't know where I can just get the bracket besides a junkyard. And well that will just mess up again.
