Looking for brakes for a Raleigh Record Ace

[Mr Weirdo]

Hello. I have a set of Shimano Exage Motion brakes but found when I tried to fit the rear one the threaded bolt(?) was not long enough. That may not be the correct term.

Any ideas what brake system will fit this bicycle other than the 605s it would of been originally fitted with.

Thank you

Hello. I bought what I thought were 605 Weinmann but are actually 570...can any one recommend suitable brakes? I have Shimano Exage Action levers but found the rear bolt on the Exage Motion brake to short for my RRA frame.

Thank you.
