I’m following up on the above thread, but my thinking isn’t yet ready for the ‘how to’ section.
I’ve started my upgrade, taken off the brake pedal, detached the old m/c but left everything piped in just to be sure I can get on the road for my Friday trip, and sawn off the new push rod.
The two methods of articulation explained previously are to either drill a detente into the end of the new push rod or; burr the end off the new push rod, and create a larger detente in the head of an 8mm bolt which replaces the existing adjustor bolt in the pedal.
Both of these methods are intended to replicate the articulation available in the OEM nipple and detente arrangement.
I am planning to take the first approach as I have neither lathe or drill press but in getting this far it occurs to me that rather than drill the detente why not just leave a push rod nut a couple of threads proud of the rod (maybe loctite in place) and let the nut ‘capture’ the nipple...
What have I missed?
