Delinked Brakes

[Shawn K]

Pretty much, yeah. Just a matter of basic math to figure out the surface area of the master cylinder piston and the caliper piston, then do the division.

Hydraulic leverage is the ratio of the caliper area vs. master cylinder area, and then master cylinder rod displacement affects how far you can move the caliper pistons.

Then brake lever pivot distance tells you how far you can move the master cylinder rod.

Then caliper piston seal width (and shape) determines how far back the pistons retract when you release the lever.

Etc. etc. etc.

I just installed a new SMC assembly on my 06A and thought to post a long term report about delinking the 06.
I have ridden 16,000 miles on the delinked 06 and 14,000 mile across the other three bikes interchangeably.
I was all about making things simple but the smc is a form of power braking. It makes for a nice response as an addition to the human input on the levers.
I have become comfortable with the complexity of the system and the knowledge, having seen @Igofar ‘s pictures, that bleeding the system yearly provides long reliable service.
I bled the system today, third time bleeding a 1300. Went well.
I won’t be restoring the link on the 06 anytime soon but the thought crossed my mind.
Meanwhile if I end up in a post apocalyptic Mad Max world where the pavement is still ok and the are no needed smc available, I’ll have no problem delinking to get in some more miles.
