I have found that my rear SLX brake is clicking when ever I pull the lever. It comes from the calipers and i’m not sure why. I think the pads or rotor is hitting against something but i’m not quite sure.

Help?

Often the sound of a sticking piston as it suddenly releases and takes up the gap, can sometimes be felt at the lever too.

Is the spring ‘clip’ piece that splits the pads, bent slightly and sticking pround of the pad surface?

Loose bolts holding the caliper down or loose bolts holding the adaptor on???

I’ve had this aswell and as coatsey says its the piston sticking, take pads out and pump pistons out almost all the way, clean, then put a drop of mineral oil on each one so it slides freely.
