That is one experience you got there... If you remember I asked about your brakes in some posts above. I was also contemplating on replacing the stock V brakes on my walmart ride instead of just replacing the pads. Although my experience is more on the "wet" side of things, I was wondering if having great pads and not so awesome brake assembly vs a good complete brake assembly would fit the bill...
I know that you have a different brake assembly than mine, I have a V brake for my mountain bike. The
shimano acera sets from amazon looks more cost effective than just buying pads for my ride...
Sorry for the ramblings on my part

I was just thinking out loud and telling you that your experience just affirmed that buying this set over just good pads is the way to go
