On one side there was a tiny bit of metal embedded into the brake pad. This was enough to cause a horrible grinding noise which is why I took them off for a closer look
|Note the vertical grooves: these are wear indicators|
|Running horizontally is the wear line of the rim (not very worn at all)|
These brake pads are manufactured by Shimano and are original equipment on my bike. Their performance has been adequate but not outstanding at all. It is, of course, worth bearing in mind other factors do make a difference: levers, cables, cable outers and of course the brake callipers themselves.
For a moment I felt rash and decided to buy some new pads even though they weren't completely worn out. After all, in nearly 3,000 miles I have replaced one inner tube and now some brake pads; whatever next? Heck, does this mean my bike is nearing the scrapheap?
For quickness I have bought another pair of Shimano pads (£10.99 from Evans) but will research alternatives that might be a bit better.
