Changing Dual pivot centre bolt

[chris2392]

Hi guys,

I have a Shimano Ultegra rear brake but would like to use it on the front,

i have a replacement bolt that has enough length for the forks but
cant get my head around how to actually take the damn things apart.

any help would be much appreciated!

Thanks

Chris

With brakes always look for the hidden grub screws.

I use Campy but from memory you dismantle the centre bolt from the rear.

Remove the loose washers and that should get you to a starred nut. This has a grub screw which locks it in place - undo this. Then you need a special tool to unscrew that starred nut /or place a bit of cloth around it and use pliers or similar (use a hex key in the other end to keep the bolt steady). When this is removed you can knock the centre bolt out.
