Was wondering why the rear brake didn't feel right.
Also, fsck Shimano for not offering piston rebuild kits. You have to buy an entire caliper and replace. 🙄

2 year warranty on those--would absolutely be covered unless you told them you mashed it back in with a screwdriver.
I was trying to replace the bottom bracket on my Rockhopper. I was fighting to remove the cranks which seemed to be put on with the might of Zeus and thought I was getting somewhere when I realized I sheared the threads on the crank and sheared the tip of my tool off. Either I made a first timer mistake or just got unlucky. Either way gotta figure out what to do next.

Update:
Hub puller also didn’t work so I chopped the cranks off the BB. Not sure if it’s considered breaking or fixing but I need some new parts.
It's difficult to work around chainrings (they would have to be cut off), but you can use a pair of Jacob's #6 chuck wedges, banged in with a punch.
The handle-d pullers suck. The "socket" style ones are much better; both can break like that, though. If a ST doesn't want to remove and you feel the pressure hit a plateau,: stop, leave the puller tensioned as is, grab a hammer, and hit it medium-hard (Driving a regular nail). Screw down a bit, and repeat. This will frequently break the static friction on the taper, and allow you to remove it. You can 'team up' the chuck wedges with this, if they're really stuck.
Usually the threads bust out from leaving a washer in the bottom of the socket (older crank bolts), or from stuck tapers.
