2020 'R' model rear brake disc

[Rocket rider]

I have just replaced my rear disc after 40,000kms it has had excessive movement for 20,000kms and I just didn’t feel comfortable riding the way it was anymore, you can do it yourself if you’re into DIY repairs, picture below is of old & new

Did you change the bolts and washers as well I’ve ordered new bolts and washers but the disc has only done 4000 miles it’s good enough to go back on but what do you think is causing the problem

Yes new bolts and washers that is recommended by triumph new brake pads. The biggest problem I had was sourcing parts two months wait here in oz , ended up sourcing from the Netherlands , as for the cause i have no answer

Don't suppose you have the part numbers handy for the rotor, bolts & washers? Mine is pretty sloppy also.

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...

@Tal There was a similar discussion earlier with some information that may be useful....

Rear Brake Rotor

Well I have been lucky so far with no problem with the mushy rear brake many have experienced but the rotor is loose and sloppy on the bolts and will need to be replaced. I have a new one on order and should be back to normal this week I hope. Anyone else experience this issue? I have a 2020...

Called my dealer... the parts come in a kit with the rotor, bolts, and washers: T2027017. Looks like it goes for about $275USD
