2020 'R' model rear brake disc

i think the pins have worn a tad ...theyre oval shape i believe and some brake clean sprayed in there may help if one is clogged with brake dust which can stop the pins from moving...we will see i guess.

Hi Tal, I saw your post on the Rocket 3R rear brake disc assembly. The bottom line - a little lateral movement in the rear associated with brakes can be a very real issue. Mine failed yesterday on a 200 km ride home. All the bolts that hold the brake disc and ABS together had departed apart from one that fell out on my driveway. I had recently had the rear brake pads replaced as part of my 42000km and the ABS was making the rear brake spongy again. That's what I thought the problem was until I finally found the condition of the rear hub (behind the wheel). See the photo. Off to the mechanic again. I can't fix that one and I fear the cost after inspecting the damage.

My cobber has an 'R' model and has put 20000kms on it since May 2020 when he bought it. He has discovered the rear brake disc has some movement in it now...side to side a tad and back and forward a bit...it 'clicks' when it rocked back and forward. To me, this dosnt seem right and we checked mine and there is no side movement at all. there is back and forward 'play'. Is this something that may develop after 20000kms or is it loose?...It cant be tightened or checked when its still on the bike....He has been told its a normal development. but we are not so sure...
