Regarding your worn disks ....

I got this from this forum, not scientific but pretty darn close:

Brake disk thickness- Penny Dime Nickel

If your brake disks have a lip whose thickness is no more than that a "Dime" - you might be able use them again.
"Pennys" - its about time to change them
"Nickel" - Regardless brake light or not, hurry up and change em'

BTW, here are the official thicknesses of the US coins:

Penny 1.57 mm
Nickel 1.98 mm
Dime 1.35 mm

The obvious note is there are two sides to a brake disk.

'03 E320 Wagon-Sold
'95 E320 Wagon-Went to Ex
'93 190E 2.6-Wrecked
'91 300E-Went to Ex
'65 911 Coupe (#302580)
