As if we don’t have enough SMC failures, most of them due to neglect, and failure to maintain the bike often enough with proper service routines etc.
I’m starting to see a new cause of failure, also from neglect.
I’ve seen two or three ST’s come through that needed fork seals lately, and two of the three, had their SMC units starting to jam up and start dragging the rear wheel.
The cause may surprise you…
The leaking fork oil, caused all the rubber bits in the front calipers to swell up and start binding the guide pins, and distorted the SMC boot enough to jam things up.
It amazes me how many people think that a leaking fork seal won’t hurt anything, and just ignore it.
Not to mention, it soaks and ruins the brake pads, and they now need to be replaced.
This swollen boot did the same thing that hose clamp did in John’s post!
