"loose" disc brake pads

[Horace Van Khute]

I seem to be having an issue with rear disc brake pads where under braking I can hear them move / shudder as if they were loose whereas the fronts are solid as they were when the bike was new (about 3000 miles ago). The braking action itself is pretty solid on both the fronts and rears.

Before I start acquiring more tools relearning how to work on bikes (these bloody modern bikes are a pain in the ass I tell thee) does this ring any bells to anyone?

Just checked and everything is in place, pads themselves feel a bit wobbly (compared with fronts). I tightened this small axle thing a bit more and will see. But something tells me I need to get some proper tools to work on this thing eventually.

The disc is rock solid, it's the hub mounted variant.

I don't want to mess with pads without having tools required to reset the suckers, but looking through the gaps they seem to be still ok.

I think in the end that I have possibly slightly bent the disc and that is causing pads to pulse. Have no effing clue how that could have happened since I didn't bump it or anything. Only thing that comes to my mind is them warping from heat. Which is quite poor.

Anyway, I can't be bothered I don't think, I'll just have my LBS deal with it.
