brake pads won't fit

I would recommend not using the 76 up calipers. I did this, and due to the larger bore, I had to change from a 15/16 MC to a 1 1/32 bore MC. The 15/16 did not move enough volume to operate the larger calipers.

I use the 15/16ths bore M/C regularly with any size caliper and get fantastic results.

Not sure what your problem was, but it wasn't the M/C.
