AP 2696 Brake Caliper

Hi Gents
Just about to purchase a new AP caliper and was researching on this site https://www.clubmanracing.com/discsystems.php and on it they make reference to a G0312 bushing, this i would assume is because the caliper mounting holes are 10mm & the support bracket holes & mounting bolts being 3/8"
Has any one fitted these bushing and wouldn't it just be as easy to open the bracket holes slightly and fit 10mm HT bolts??

Drilling out to 10mm sounds ok to me. I've been thinking about following Old Britt's advise and putting a helicoil in the caliper instead. https://www.oldbritts.com/14_000004.html

Yes, Use 10mm..... Unfortunately that can't be combined with the helicoil in the caliper, which is a good approach!

My own AP calipers are mounted the opposite way....but not on Norton forks.....I have the bracket on the inside of the caliper, and I have threaded the brackets!

The bushings must be pretty thin!

For sure... 3/8 equates to 9.5mm....wafer thin!!

If you've never seen this it's worth a laugh

I'm guessing I'd better get a bucket?
