[Closed] Post Mount Facing, Bristol Area

Hey guys

Bit of a strange one this, I'm having real problems centering my calipers on my post mount forks. I can center the caliper perfectly when the brake isn't on but as soon as the brake is applied hard the disc is warped.

I'm convinced it is the facing as when the mounting bolts are slackened off and the brake applied the caliper is also square the the disc buy as I torque up the mounting bolts against the mounts the caliper is pulled out of true relative to the disc.

So does anyone have any ideas if this can be sorted to home or know of a shop in the Bristol area that can do post Mount facing.

Thanks

David
