As I mentioned before, I had locking problems with Glennis brakes. I have to admit, that I could probably have made them work by experimenting with lubricant, but they say you don't need it. For the size tires that I had, it was $16 for a replacement. BVM was only $10. And the other thing you had to deal with from Glennis was the wait. Dennis would not stock them always or he would wait till he felt like sending them out. Either way, you'd better plan your tire usage, cause he ain't gonna get it to you in a timely manner (or at least that's the way it was a year and a half ago).
