Nepkire Posted July 22, 2014 Share Posted July 22, 2014 Hello I have an issue I am unsure what is causing the problem. fyi I am a newbie to working on cars as this is the first carI have ever done any work on. My rotor was grinding on the caliper mount as the initial problem. I needed to turn the rotor and buy a new caliper (the old one was covered in rust and the pins did not move well. After I had the rotor turned I tried to put it back together with the new caliper and ran into this problem. One picture is the caliper mount and rotor, the caliper mount's bolts have not been tightened all the way and could not without damaging the rotor. In the other photo I took the rotor off and tightened the bolts on the caliper mount all the way to show how it sits. I have no clue why this is so far off.

apexi Posted July 22, 2014 Share Posted July 22, 2014 In the first picture, the rotor definitely looks like it might be on the hub crooked, it appears to be tilting forward more towards the top of the image. Make sure the brake rotor is fully seated on the hub. When you're looking at the rotor, make sure the part of the hub I circled in red below is sticking out an even amount. I'd also be careful with reattaching the brake line to the new caliper. I've never installed a new caliper, but I'd be worried about the possibility of introducing air into the brake line.

MeoW71 Posted July 23, 2014 Share Posted July 23, 2014 Definitely make sure the rotor is flat against the hub. You can always use one/two lug nuts to make it flat against it. Hand tight is good enough. That really does look off. Did they give you the right brake caliper and bracket? Link to comment Share on other sites More sharing options...
apexi Posted July 23, 2014 Share Posted July 23, 2014 Good idea with the lug nuts, I never thought of that. Link to comment Share on other sites More sharing options...
Nepkire Posted July 23, 2014 Author Share Posted July 23, 2014 I did try to use a nut to tighten the rotor all the way back onto the hub and then I wasn't able to tighten the caliper bolts on all the way, about half way tightened and the rotor was against the caliper mount. It is the correct caliper, the model number on it was the same as the one I had taken off earlier. Link to comment Share on other sites More sharing options...
Tundraman Posted July 23, 2014 Share Posted July 23, 2014 Is this a rebuilt caliper? I've had some that had odd (non-oem perhaps) caliper mounting brackets that were poorly made, resulting in the caliper being out of position. Do you still have the original bracket to try?

MeoW71 Posted July 23, 2014 Share Posted July 23, 2014 Did you compare the caliper part number or the bracket part number? You could use the same caliper on different brackets, so the bracket part number isn't always the same. Link to comment Share on other sites More sharing options...

I already returned it for the deposit. I will compare to the caliper on the other side. Link to comment Share on other sites More sharing options...
Nepkire Posted July 27, 2014 Author Share Posted July 27, 2014 This is the front right side. And the caliper mounts side by side to compare. **I added the very first photo I took after parking the car. This picture has the original caliper on it and the rotor before it was turned.

MeoW71 Posted July 27, 2014 Share Posted July 27, 2014 Well, I'm out of ideas. Not sure what is up. Is the hub really off that much in the fourth picture? That really looks like a big gap between the rotor and the dust guard. Lastly, IMO, don't return deposit parts until you get the new part installed. No point in doing that in case you have to get a refund because the part is wrong, since the shop will probably no longer have your old part.

Nepkire Posted July 27, 2014 Author Share Posted July 27, 2014 after doing some research I decided that I will take the hub and bearing out and check to see if I need to replace it and if not have it repressed back into place. Link to comment Share on other sites More sharing options...
