« on: February 15, 2026, 04:17:39 AM »My rear brake mounts are crooked. Centering the calliper and before fully tightening the bolts I can see almost a mm bigger difference on the side towards the wheel which results in the rotor always rubbing hard on the left side.
Any home fixes for this or should I find a bike shop with a facing tool?
I had the same, caliper leaning right (looking from behind) when tightening beyond 2-3nm to the suggested 5nm (so last bit of tightening). I fixed it myself, but probably not the recommended way.
I checked with a (aluminium, straght) ruler, took a hobby knife and very carefully shaved off (really lightly shave, make sure to keep the knife flat, no hard cuts!) the paint/clear coat overspray layer by layer, checking with the caliper in between shaves to see improvement. I only did it myself because it was very obvious where the high spots where (you could see the paint on the brake mount after tightening), so I had a very good idea of where to shave off bits.
Took me 2-3 hours but now it's straight enough that I can tighten without it rubbing.
While this worked, if I had known an address near me that does facing, would probably have gone there
