Caliper not aligned to disk
Posted: Thu Jun 13, 2019 8:16 pm
Hello All,
A little help if you please.
I am in the gradual process of building up a Spyder chassis for for my 71 +2 S130 but have come to a grinding halt.
All looks ok, but when I try to fit the caliper onto the Spyder hub carrier the disk fouls the inside of the caliper. I reckon it's off by about 3mm.
It's the same on both side.
Here's a pic showing the large gap to the left of the disk and no gap to the right:
(forgive the rubbish caliper paint job!)
Spoke to Spyder and they said that have seen cases where the faces of the drive lugs have been machined back resulting in a misalignment. I don't have a reference piece to hand but mine are a nice square half inch so I suspect ok:
This made me think that perhaps I had not pressed the axle in all the way, but I can't see how it could go any further. A precise 2 inch protrusion makes me think all may be ok:
Likewise, a exact 1 inch gap from the drive lug to the caliper looks like it may be correct.
But alas it can't be. Something has to be out and I just can't see what.
If any one has a successfully assembled chassis to hand, it would be great to know how my measurements compare.
Thanks,
Humbuck
