Disc run out

[Speedy1959]

Hi all..
Finally got the dial guage up and running.
It showed a localised high spot of .25mm on my right disc.

Can I just ease down the mount location under that one location point or to correct the deviation caused by the powder coat?

If the answer is yes then would the disc correct itself?

Or am I day dreaming and would have to bite the bullet for a set of new discs?
As well as try to remove the powder coat from all mount surfaces ??

Come on Gurus.....
Whats your verdict?

I darent ask Andre !!!

Before doing anything else remove wheel and both discs and clean the mating surfaces and while thier off make sure the buttons are mega clean and free then then refit all and see where your at retry .
Good luck buddy

I may not have read everything in your post

It's possible that this is caused by the powder coating but there are other possible reasons. They have all been mentioned on this forum.

Get rid of the powder coating, establish that the mounting surfaces are plan or make it so, mount the disc (first might want to use the oven treatment as Seth suggested) using cross pattern while torquing it in steps. Measure the run out again. If it is still there, ride it and see if it resolves or gets worse. If it doesn't get better and you decide not to live with it, get a new disc and pads.

Simon - you have to start with clean faces for the disc to bolt onto, so the powder coat has to come off all the mounting faces first where it shouldn't be.
