Dana 60 caliper loose?

    I am installing a Dana 60 in my '80 K10. I was installing the calipers and pads, and I slid the flat plate/clip in at the bottom, and installed the single 5/16 allen head screw. There seems to be a lot of play between the grooves machined in the caliper and the lugs on the part the caliper mounts too.

    One of the calipers is from Auto Zone, one from Advance Auto Parts, they both appear to be about the same quality wise. I had to pretty much beat the original ones off (which means they weren't loose like the new ones), and they were beyond salvage.

    The Advance caliper came with a slip of paper, talking about measuring clearances between the grooves I've already mentioned, and mentions installing oversized keys. I think that is what the plate with the 5/16 bolt in it is.

    Have any of you had any experience with this? Ever need to get these over size keys? Where'd ya gettem? I'm not sure if Advance would sell the keys, they seem like a GM part. Yinz have been helpful before, I'd appreciate some advice. (Not gonna get rid of the D60!)

    I'm rebuilding that area myself and would appreciate an exploded view or something myself.

    Thanks

    After I had my hubs turned down, I reused my calipers and I seem to have some play in the pads. They move front to back about 1/8". Does anyone have any thoughts on this as well.

    There is a spring clip that needs to be installed, and the key can be purchased is several sizes to take out the play.

    The spring clips went back in. Had to tap the springs and plates in together, very snug. Reused all the parts, nothing was replaced.

    are you actually talking about the caliper itself or the brake pads?my new calipers on my dana 44 came with different size bushings to make the caliper not be loose.i got it from national auto parts.i dont know about the 60 but it should have came with some kind of bushing i would think to help align and tighten the caliper.like others said.there should also be a spring inside the caliper to push the brake pads together so no rattle.

    The pads are tight against the rotors, but they can move front to back (rotationally) withing the calipers.

    MJ, I did install the spring clip, I forgot to mention that in my post. There still seems to be excessive play. Derf00, one of the caliper kits did mention oversize keys, I haven't had a chance to go back to the parts store yet, but it seems unlikely they would carry them. Where did you get yours? Thanks!

    Mine did not require the oversized key, but they are apparently available, you may have to order them.

    i think that is normal movement,
    I thought you were refering to the caliper moving

    Well, before I buy anything, I think I'm going to go ahead and bleed the brakes, to get the pistons pumped out and a little pressure on the pads (drivable). Then I'll see if the clearances/movement are excessive or not, and if it drives well, I won't worry about it. It just seems pretty excessive at this point...
