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.
