Recabled the lads cyclo cross bike's rear disc brake. Still crappy high friction cable leads. Gah ! Took it apart one bit at a time to work out where the resistance was originating.
Determined that the front entry point for the internal cabling still had the old cable end in which was forcing the cable through an ugly angle. Phew. Was on the point of considering giving up on the internal routing completely. Will finish it off tomorrow.
This will mean a second new front outer cable and re-taping the bars again. Bah !
Job done. That took waaaaaaaay longer than it should have. Managed to knock the errant ferrule into the tube.
"Aha !" Thinks I, remove the seat post and turn frame upside down and shake. No dice. That end of the top tube is blanked off.
Drop the fork out and go fishing with a hooked implement dosed with sticky stuff. Success.
Bloody tedious though.
And, at the end of it all, it's still impossible to adjust the rear brake (TRP Spyre) so that the pads don't drag and the lever doesn't run out of travel before it hits the bar, even though the lever on the caliper is now returning (almost) all the way.
Adjusters on the caliper are screwed all the way out.
All I can think of now is to run it around a bit and wait for the pads to wear out and bed in.
I have to say, this experience doesn't inspire me to affix cable disc brakes to anything.
