I have a Schwinn Rocket mountain bike with front and rear V-brakes. While removing the rear brakes to be replaced with higher quality ones, I managed to twist one of the brake posts out of the frame while it was still attached to the brake itself. It appears that the brake/post bolt is seized and won't budge.
How much effort should I invest into separating the bolt, brake and brate post trio? The whole train wreck is soaking in PB Blaster overnight, so I'll try one more time tomorrow.
It seems to me that a brake post is the type of hardware that I should be able to buy at any bike shop. However, as with anything coming from the highly balkanized bicycle industry, I'm wondering whether there are many sizes of brake posts out there. How can I tell which one I need?
