I guess we should break the question into the 4 categories of front rotors, rear rotors, front pads, and rear pads. How long (miles)?

 

Pad longevity is directly porportional to the way you drive. So "how long your brakes will last" is not an exact science. Could be 15,000 miles. Could be 45,000 miles

 

That's a trick question for me.... my rotors go before the pads.

I have to say
(Front) ~25K stock pads/rotors
~40K Stillen Xdrilled/metal matrix pads
current ~45K on Brembo blanks/Raybestos QS
(Rear) 101K never replaced original pads!!!

 

The OEM rotors and pads suck. Warped the front rotors around 12K and had them redone at 33K (under warranty, NTB00-088a), when the rear pads went (5% left, compared to the fronts at 50%). I'm at 60K so I's sure due for new rears I'm sure, but his time no way in hell I'm going OEM.

 

My brakes lasted -

Stock - Warped somewhere between the assembly line and the delievery truck :rollseyes: Dealer resurfaced twice and actually wanted to do it again for the third time. Pfff.
Stillen X-Drilled with Porterfield R4S - I honestly think they warped within 2 weeks after install. Gooooo Stealin!
PowerSlots with the same Porterfield R4S - Over 2 years and still performing great =)

This is just my experience...
