I recently (a few hundred miles ago) changed the = brake pads, piston seal and dust cover on my Syncro.  The previous = brake pads were screeching when not activated.  Now the new brake = pads (ATE, Made in Germany) started making a 'bonking' sound once per = wheel revolution when not activated.  When I step on the brake = pedal the bonking goes away.  Does anyone know what's going on = here?

Many thanks,
