I have newly restored calipers from PMB. They look great. Front went on no problem. The rear have been a real bear. I've tried both sides and I can't get reasonable clearance between the caliper (no pads) and rotor. I wonder if I have the alignment of parts wrong. (IMG:style_emoticons/default/confused24.gif)
My understanding, working from outside in, is: Trailing arm mount <- cover plate bracket <- caliper <- bolt Meaning the cover plate bracket is sandwiched between the caliper and trailing arm. Do I have that right? I tried the reverse as well and it still didn't line up well. (IMG:style_emoticons/default/blink.gif)  Not sure what I'm doing wrong... Damn you Ian Karr and your videos that make this look so easy. (IMG:style_emoticons/default/biggrin.gif) P.S. As you can see in the photo, the rotors are not vented so that should not be adding to any clearance issues. |

Is the stub axle tightened in the wheel bearing /hub ? Is the rotor tight on the hub ? The order of the caliper mount looks right. |

Stub axles are not installed yet, so I literally have some wiggle room. The rotor is tight on the hub. 2 retaining screws installed. Both sides. |
