Screeching noise when I break.

[Glow]

So my back wheel brakes were screeching really loud when I use them so I put in new brake pads. They were working fine at first but the screeching is back after a day. Why is it back I got New brake pads?

Did you do the bedding in procedure with the new pads ? And clean the disc with some cleaner, I use Brakleen .Also since I switched to Jagwire ( semi - metallic ) disc pads , on my St2 ,these solved brake squeel for me. And they last lots of miles.

On my bike I had 3 loose screws on the disc. I could not tell they were loose until I tried to tighten them. This cured my screech.
