My Bentley manual has this in a "caution" box in 46[Brake-Mechanical
Components]:

"When machining brake discs, equal amounts must be taken off each side of
disc.  Never machine one side only."

...and the wear limit is 13mm...

I'll measure them...

and for the rear:

"...maximimum diameter after machining: 253mm (9.960 in.) (use oversize
linings after machining 0.5mm (0.020 in.) or more..."

Nowhere does it state "do not machine".

There may be a TD for this, but I'd have to ping Joel for that, and I don't
really want to hear it anyway.
