middle sliding door track is grinding

[pjstock]

greetings all!
it's been awhile since I pestered the Forum (did you miss me?)

even though (with your help) I managed to get all the systems working correct, we didn't manage to venture very far from home this summer - several circumstances conspired against travel. (among them though, the fact that all the camp grounds in Canada were fully booked all summer, as Canadians are staying home and not visiting the USA. Plus, half of western Canada seemed to be on fire all summer.)

I do have another maintenance question.
My middle sliding door track is grinding at the last phase of closing. .
I understand this likely has to do with debris in the track and lack of lubrication. But I was looking for people's past experiences.

I expect this is a common issue that has been addressed here. But when I search "sliding door track grinding" or "sliding door lubrication" I find 0 posts.

am I missing something?

Hallo Peter,
es könnte auch sein, daß die Laufrollen der Schiebetür, die ja aus Kunststoff sind, verschlissen sind, mittlerweile im Durchmesser verringert sind und daher der Träger an der Laufschiene schleift. Für den T1N müßte es die Rollen als Ersatzteil wahrscheinlich noch relativ günstig bei der Sternwarte geben..... Viel Erfolg bei der Fehlersuche

Looking at it more closely this morning, I expect that you are correct - that the small upper rollers are worn and so have a reduced diameter and so are not holding the bracket away from the inside face of the track they way they should

can someone advise how I remove that bracket (with the rollers) so I can inspect, repair or replace?

is there just the one bolt.?
and then I would release the back end of the track and slide the loose bracket out?

easy to remove.
this video gave me confidence

one small roller does have a lot of side to side play in it. that probably isn't "normal"
but the rollers do not look Replaceable.

so I. will order a whole new bracket
(though I am not sure it will be as easy to reinstall)
