The fiancé picked-up a 2003 9-5 Aero Sportcombi in LB. No joke it looks like it could be that color!
Anyway...
Her rear brake pads are due to be done like ASAP down to 10-15% left on there and winter is coming up. I cannot seem to find the recommended rear rotor minimum thickness. Anyone have that?
Also, I doubt it the rear brakes do much work...but anyone think the roughly $40 jump to the GS sport slotted rotors for the rear rotors are worth it?
Usually a shop that turns them can tell you and measure them. I'd suggest buying replacements anyway, it's not that much more. I personally would not upgrade to slotted on my wifes car unless it was for appearance. My 2 cents is to save the money and not buy slotted, but replace them completely.
Anyway, my WIS for 1999 9-5 ( i think the 2003 rears will be different) says they were 10mm new, and 8.5 mm minimum permissible thickness after grinding. That should give you an idea at least.
I know that a shop can normally tell you that. I plan on doing the brake job myself. I do have a micrometer and I planned on taking a few measurements. I just couldn't find record of a minimum thickness indicator.
I am glad to hear that you are thinking the rear brakes wouldn't benefit much from the slotted rotors. I think I will just order them via my local parts store as they are $1 more for the part then GS but w/o having to pay shipping costs.
Thanks for the info/opinions.
Anyone else have input? Actual minimum thickness info for Aero rear rotors? Opinions on slotted vs. not...
I found some Wagner ventilated rotors at are OE replacements for $55.99 each at my local OReilly. They have to order them in $13 shipping. Cheapest total cost I could find w/o having to wait forever and good quality.
minimun thickness for standard vehicle is - 8.0mm (0,32 inches)
heavy car - 18.mm (0,71 inches)
maximun grinding dept standard vehicle is - 0.8mm (0,032 inches)
heavy - 0.8mm (0,032 inches)
minimun permissible thickness after grinding standard vehicle is - 8.5mm (0,33inches)
heavy vehicle - 18.5mm (0,73 inches)
thickness (new) standard vehicle - 10mm (0,39 inches)
heavy vehicle - 20mm (0,79 inches)
there is more involving diameter and runout tolerances but i think you don't need that. If you do please hit me back up on here and i will be glad to post.
take care have fun with the wifey's great find. welcome to the saab life.
