Glorian Posted May 13, 2016 Share Posted May 13, 2016 Been a while since i posted here which is nice My rear brake has recently started to squeal intermitently. Not every time i press the lever but enough to start to bug me.I've had new pads on recently and i've sprayed some brake cleaner over the disc also, but not much seems to be going on.

mealexme Posted May 13, 2016 Share Posted May 13, 2016 Hey GlorianThe squeal usually comes from the vibration between the brake pads and the pistons in the caliper, so it's best to put some grease on the BACK of the pads - the bit between the pad and piston, but it might also help to put some on the pin that the pads sit on. Basically, anything the pads touch EXCEPT THE CALLIPERS. Quote Link to comment Share on other sites More sharing options...
Glorian Posted May 13, 2016 Author Share Posted May 13, 2016 I usually put quite a bit on the back of the pads. Might take them off and re-grease everything just to be sure Quote Link to comment Share on other sites More sharing options...
eastanglianbiker Posted May 13, 2016 Share Posted May 13, 2016 it could also be the pads glazing up so if you are taking then out might be worth giving the pad surface a little rub with coarse sandpaper or something similar to break up and glaze that could be on them Quote Link to comment Share on other sites More sharing options...
megawatt Posted May 13, 2016 Share Posted May 13, 2016 Some pads come with anti squeal shims as well. Quote Link to comment Share on other sites More sharing options...
Hoggs Posted May 13, 2016 Share Posted May 13, 2016 Sounds like the bikes knackered. You should buy a nice new green one Quote Link to comment Share on other sites More sharing options...
Fozzie Posted May 16, 2016 Share Posted May 16, 2016 I put a smear of copper grease on the back of the pads when I reassembled the caliper but squeaks do happen as after a couple of washes the grease is washed away Brake cleaner is like a 50cal to copper grease so just take the caliper off, drop the pads out and give the backs a clean with some new grease. Just clean up the piston while you're there to put off having to do it again and that should solve it. Quote Link to comment Share on other sites More sharing options...
Lumor_uk Posted May 19, 2016 Share Posted May 19, 2016 I put copper grease on the backs of mine then ragged the poo out of them. Fixed mine. Quote Link to comment Share on other sites More sharing options...
Guest Posted May 19, 2016 Share Posted May 19, 2016 Use red rubber grease on pins, not copper slip Quote Link to comment Share on other sites More sharing options...
megawatt Posted May 19, 2016 Share Posted May 19, 2016 Red rubber grease is for brake seals, not steel pins. Quote Link to comment Share on other sites More sharing options...
