Gents. On my HT I have the famously crap Avid Elixir 1s which I'm going to have a crack at bleeding in the near future but yesterday whilst cleaning the bike I noticed the back disc was running about 1mm out of true which obviously won't help.
As the warp was even (rather than localised) I trued this with my bare hands and got it to about 1/2mm. I'm reluctant to try and get it down further for fear of going too far the other way.
What is the generally accepted run out on discs? Any other comment or tips for truing?
It strikes me that this must be a common problem given how laterally flexible the discs are.
Thanks A |

i wouldnt have thought that a 1mm warp would be noticeable....

As long as it's not fouling the pads i wouldn't worry about it.

With a bit of luck... The 1mm will encourage your avid caliper to blow up... In turn, forcing you to buy some more brakes  |

I find the best way of tweeking rotors is to use an adjustable spanner.

A good alpine holiday always seems to help with this, the amount of heat generated tends to relax and reset them.
Consumer advice there.

Just put the bent bit between two bits of wood and smack fk out of it .. Other wise buy a new one if your not happy with it .. Call it a little crimbo present to your self.   |

Even new discs might not be true and have a little run out, I aim for < 0.1mm, 0.5mm is a lot. Making lots of small adjustments is better than giving it one big bend which can make things worse.
