Sidmouth Posted November 25, 2013 Share So I put in new pads, on my SLX calipers, different manufacturer of pads..Spin the wheel no problem, test ride down steep hill to test and I hear this sound of something touching, sounds like a broken spoke noise.On closer inspection the only thing i think i am seeing is that these new pads sit further down on the disc and the noise could be coming from the disc as that part of the disc has never before come into contact with a pad.is this normal and will a few rides smooth it out?

porqui Posted November 25, 2013 Share Are you sure it is the correct pads and did you bed them? Link to comment Share on other sites More sharing options...
Sidmouth Posted November 25, 2013 Share The pad is correct as per the fitment, but what is bedding? Link to comment Share on other sites More sharing options...
DR ◣◢ Posted November 25, 2013 Share The pad is correct as per the fitment, but what is bedding? Pads and discs need to play well together. Neither are truly flat and only once they "bed" in do they work as they should. To bed the brakes in people employ different methods. Mine choice is to find a nice long hill. Get the bike up to speed and really climb on the breaks. Repeat 10 times. After that the pad and disc will now be good friends. Try not to kill yourself. Make sure your weight is way back when you hit the brakes. dalem44 1 Link to comment Share on other sites More sharing options...
Sidmouth Posted November 25, 2013 Share Brilliant, I was hoping that would be a solution,Let me give that a go.so these new pad issues are totally normal? Link to comment Share on other sites More sharing options...
King_Crispy Posted November 25, 2013 Share 10 times repeatedly might be a bit much. You gotta be careful you don't overheat the pads/disks and glaze them.Ease them in over the space of 2 or 3 rides -Az- 1 Link to comment Share on other sites More sharing options...
