When you are flipping a bike of marginal quality, what do you do about the bake pads? I tried getting the cheapest pads at the LBS for the last bike I fixed, but they worked essentially no better than the 27 year old pads worn down to the nubs, so I took them off. I don't like the idea of spending $20 just on brake pads for a bike that many sell for $60 or $70, but neither do I want to sell a bike that is unsafe to ride. So what do you do with the low-level beater bikes? Strip them down, sell the frame and recover what you can from the components?
