The Type 12 calipers look like they've seen better days so I was considering an upgrade to the Type 14 as has been discussed in various threads here. Due to the clearance issues, I bought a pair of Type 14 hubs from eBay as it seemed easier than grinding the edges to clear the calipers and they were going cheap. But what bearings do I fit to them? There seem to be two different sizes and I don't know whether it's the stub axle or the hub that differs, or possibly both. The GHK1011 kit seems to be for the Vitesse, but the GHK1021 kit fits the Type 14 hub.
Once the bearings are sorted, is it just a case of swapping the calipers and fitting Type 14 pads with the original Type 12 disc or are there any other gotchas? I'm hoping to do this in two stages - hub swap first and caliper/pads after payday.
Thanks in advance for any advice.
