200sx/maxima rear disc conversion on a 510, rears dragging?

[68Datsun510]

Hey folks, i recently replaced everything in my rear disc system. Rust had gotten into my calipers while the brakes sat for years. They are 83 200sx rotors, and 87 maxima rear calipers. Mounted upside down to retain the factory e brake cable system. Took it for a nice drive today, and the original vibration i started with 3+ weeks ago is finally gone. But, when i stopped, the back wheels were considerably hotter than the fronts. Attached is a photo of my rear disk system before new rotors, calipers/pads. I have verified time and again that the cables are slack and that the e-brke levers are resting on their stops. Another oddity, is that ifi come to a stop on ground with even a slight grade, the car WILL roll, so its not like they are dragging hard...

 

Now, i installed the pads into the spring steel clips with no grease. And it actually required taps with a mallet to seat the pads against the rotor.

 

Hoping its a simple solution or I am stupidly missing something here...

 

Any suggestions?

1. They should seat with your fingers. Take the pads off, and scrape the sliding surfaces (both pad and caliper), and use a wire brush. Get them moving freely.

 

2. Use light, light grease on the sliding surfaces. You don't want it anywhere near the pad friction material or rotor, but it needs a bit of lubrication.

 

I had exactly the same symptoms with my Datsun.

Thanks GG, upon doing just that ^ i came up with another theory...The spring steel inserts that guide the caliper, also act as the bearing surface for which the caliper rides on. WIth my calipers mounted upside down, the bearing surface is now rough cast iron. I think I am going to have to re-orient my calipers if what i did today doesnt work.
