Machining the corner of an apex seal slot on a rotor...
Hello guys. Please forgive me if this is inappropriate for me to post this if their are millions of similar threads related to this topic but I do have a is-this-good-to-use-kinda-question here.
The clearance of the apex seal while on the slots are within specs EXCEPT for this that is on my front rotor and another in the rear. Would sanding a bit on the corner where the apex seal has a hard time getting inserted, shown in the picture, be alright or will that cause internal leakage?

Yup, it got dropped.
A single cut flat file is the best for cleaning up big boo boos in the rotor slot and then you can adjust the clearance with fine sandpaper wrapped around the flat file.
Make sure you file the side of the rotor as well so no part of the dent sticks out past any other part of the rotor or it will contact your side housing.

True, is always better than not true.

If the corner seal is sticky you can fix that as well.
You can put a brass punch in the hole and gently pry it back open or very very gently hammer it out.
You can also just clearance it, but if you do that you must make sure you ONLY remove material where it has been dented in (toward the opening). The last thing you want is for it to be sloppy down in the bore allowing the corner seal to get cocked sideways.
Next make sure you check the side seal clearances with the corner seal removed so you can run the feeler gauge all the way through the end of the side seal slot since these can get dented in as well.
