rotors minimum thickness

shipill · 10-08-2010, 10:18 PM

I need to replace my rear brake pads soon and my rear rotors are at 21mm and the minimum specs for rear rotors are 20.4mm

Do the rotors need to replaced?

Thanks.

As far as thickness goes ur fine to re use. I would just do a visual on them as far as rust along the outter edge.

When I did my front pads i decided to replace the rotors aswell. Rotors had enough meat left on them but decided put all new since i plan on keeping the car for awhile.

I think it is always a good idea to replace rotors & pads together.
