After many suggestions and a visit to a machine shop, I decided with this solution. I tapped out one end from the 7mm hole to a an 8mm thread. The other end I just bored out to 8mm. It now takes an 8mm socket head bolt, without a nut, just like the later callipers. Total cost of all bolts $12, instead of the $16 per bolt plus delivery from the UK.
Looks like a working solution to me.
Makes you wonder why Ate chose such a strange bolt initially when producing these. Eric?
I think Ate used the odd bolt size to keep somebody from rebuilding the calipers with the wrong (low strength) bolts. 7mm is a very strange bolt size and was probably only available from Ate. I am sure they would not sell them to everybody back then.
The calipers on my 1997 Mercedes are attached with bolts with 18mm heads. I think it has the same purpose.
This makes a lot of sense as the 7mm bolt holes are on the sloppy side. If you ream the holes to barely accommodate 8mm bolts, the assembly will be plenty strong.
Hi, I'm in Victoria too. Sorry I didn't see this sooner.
If you need any 914 help call or send me a text. I have one of the local parts hoards....including brake caliper bolts.
