[TR] Spit--dragging brake caliper

[Tim Gaines]

I put remanufactured brake calipers on my 1980 Spit last summer along 
with new rotors and new hoses from the brakes to the brake lines all 
around.  The right caliper must be rubbing the rotor without the 
brakes applied as I get pretty extreme pull to the right while 
driving; when I apply brakes it evens out.  Overall, the braking 
action is pretty weak.  I have to push very hard to get a good stop 
when I am at even moderate speeds.  As a result I haven't driven it 
at all over the winter.  I took it on the road yesterday, with the 
same problems showing up, and now I have some time to work on it.  Am 
I looking at a brake caliper problem for sure, or could there be 
something simpler (less expensive) at fault?  Is it possible for air 
in the line to affect one side that way?  Even if the PDWA valve 
isn't centered, it wouldn't affect left-right brake action, would it? 
Believe me, I'm going to try to bleed the system before doing 
anything else, but is there any chance that I will cure the drag by 
doing that?

Thanks for any advice,
Tim
