Got these on 17 days ago and probably done no more than 60 miles. The main commute is 6 miles. 4 of that is a steep downhill.

    You should show and check how you mount those on your bike. Didn't they rub all the time? Weren't you breaking with just one pad? – Vladimir F Feb 27 at 15:25

    Sorry I should explain one is a spare – Aron j Feb 27 at 15:32

    They could well be fake products. Trying to imitate Kool-Stop. – Carel Feb 27 at 16:56

    Do you brake continuously on a downhill or something similar? – Criggie Feb 27 at 18:07

    You say "new rim brakes", but you don't say "new rims". What is the condition of the rims? But if you do in fact run some steep downhills then the wear may not be excessive (though you might do better with a different type of pad that is "harder" to wear more slowly -- at the expense of braking power). – Daniel R Hicks Feb 27 at 22:49

Looking at the design of the brake pads, this appears to be a cheap generic pad that is then re-branded (in different colours) by various manufacturers.

Reviews seem to be mixed, with reports of the pad wearing quickly, but other reports of the pad lasting forever and wearing the rims out quickly.

I'd suggest that when it comes to brake pads, this is an area not to look for cheap replacements. Either use the brake manufacturers own pads, or ones from well respected third parties such as SwissStop or Kool Stop.

Check that they aren't pads for carbon wheels. Those will wear quite a bit more quickly if you are using them on aluminum.

  • Good thought - the carbon pads tend to be green or yellow, but not impossible. – Criggie Feb 27 at 18:06

Maybe it wasn't quite aligned with the wheel. In the image it looks like the end on the right is warn almost all the way through while the end on the left still has a lot of padding left. Pads can wear out more quickly when they don't make even contact with the braking surface.
