I have a 99 VTR250, and I took it to a mechanic for a minor service and to get the brakes checked out. The mechanic said the brakes were fine, however I'm not really happy with the front brake. When I apply the front brake, it seems to make a scratching noise and doesn't seem to give much stopping power. The mechanic showed me theres plenty of life left on the pads. However I got to thinking, what if the pads are the original ones that came with the bike? Its only done 30,000km so its possible they are the original pads. Do pads become less effective with age?
