if you got to "true" new discs, then you are buying junk! I have used
everything from OEM to "cheap made in china, Brazil, Canada, etc" and as yet
never had to do that. How does one tell a customer the discs are $85.00 each
then another $50 to true them up??????
Sorry I don't agree Peter.

Discs as delivered from the factory are only roughly trued, such that
they may be slightly warped, dished or otherwise "not quite right".
Installation without truing may make an original problem worse than
before.
Any competent garage will true a new disc. Many shade-tree mechanics
don't have a lathe for the purpose.
Truing does *NOT* mean *cutting* - if a full cut is needed then return
the disc as defective. What it does mean is that the disc might be
touched up to make sure that both sides are fully parallel and
square.

You are certainly entitled to your opinion. But even if you are using
your "free" labor and the discs are not true on receipt (and in my
direct experience, *NONE* of them have been so such that the exercise
has not been beneficial), you will not only have to do it all over
again, but you may also have to replace the pads all over again as
well. Mercedes, Volvo, Saab, VW...
I take the position that suspension and brakes are the two most
significant aspects of general car safety and require the most
scrupulous, over-cautious maintenance. The consequences of neglect or
"good enough" are too horrific to contemplate.
Yes, I do my own brakes most of the time. But if discs have to be
replaced, I drop them off at my mechanic to true before installation.
For the $20/pair it takes (he does not have to remove and re-install
them, after all), it is cheap insurance.

sounds like a waste of 20 dollars on your end, but if it makes you happy
maybe not a waste

Nope. No waste at all. When the grandkids ride on the work of my
hands, belt/suspenders/velcro is the norm.

Two thumbs up Peter! Do it absolutely right the first time! ;-)
Most of the new brake discs I have seen run straight and true, but I have
seen some that were slightly off and needed machining. These new warped
discs are quite rare!
Of course the used discs are usually junk (too thin and/or rusty) and need
replacing!
I laugh at the Midas SecureStop brake service commercials as the car flys
through the window! lol
Actually I have seen someone drive through the front window of a shop barely
missing some compressed air/helium tanks.
They lost control of the car but avoided hitting oncoming traffic as he
drove across traffic and through that glass.
Be Safe!
JMHO
