Try travel agents - they are cams you put inline to basically increase the
amount of cable your road levers pull.

you could use some old shimano levers that release at the levers as well as at the calipers...
But you are probably using STI ..

The other option is to release the cable housing from a Cable Stop. You can shorten the cable housing stop maybe so that it is shorter to pull out.

Or  have an easy-to-turn adjusting nut.  Normal position would be way up.. Then spin it down for tire removal

Any of these would probably be easier then trying to redo the cam  / toggle-over-center mechanism.  Although for sure some sort extender off the cam or etc could be fabricated / made...  its just that there seems to be many different caliper cam designs out there ? that each one would probably need to be custom.

Problem:

standard caliper brake eccentric will not spread the calipers wide enough to
pass big tires.

Question:

Has anyone made a modified "cam" to allow the calipers to open wider?
It
seems to be a simple problem.

Problem:

standard caliper brake eccentric will not spread the calipers wide enough to
pass big tires.

Question:

Has anyone made a modified "cam" to allow the calipers to open wider? It
seems to be a simple problem.

Does anyone know the size of the thread that fits the fender mount tabs on a
Trek 1000?

It looked like a 4mm but didn't thread in easily.

Thanks.
