Does any one know what type of screw / bolt is used to attach the disk brakes to the front rim? Attaching the main unit to the front arm is ok but i did not get anything to attach the disk (2nd hand brakes). 1: is it screw or bolt? 2:length of screw 3:diameter of screw
self tapping screw 35mm in length approximatley3.5/4mm in dia dome head would also benifit from being a countersunk as it does run pretty close to the front fork,my original screws were in a stainless/zinc form. Hope this helps G
(2nd hand brakes).
