660 front hydrolic brake locking up

Hey Everyone,

Just had a quick question; I am having a very weird issue with my front right tire. It seems to lock up completely at random. I cant get it to do it when I want it too, but the last 2 times I have gone riding, I notice my one front time locks and wont move (usually in the parking lot – thank god). It fixes itself pretty quickly but my only assumption I can come too is that the inside of the break line is starting to deteriorate.

Would this make sense? or would I be better off to just flush the line, refill the fluid, and see how it goes on the next ride?

Thanks,
