9.4" Vented Rotor Upgrade Debate

I finally wore out my 9.4" Solid Rotors with mintex pads after about 31k miles of driving. After talking to Potterman he verified that i can upgrade to Vented Rotors, so long as i get the right pads for them, so i got the Slotted ATE's and Ferrodo's and threw them on the day i got them
(my old brakes were pretty dead
)
BUT..im getting a constant dragging noise from the brakes. Its strange..ive checked and rechecked my install. It doesnt do it when the brake are cold or hot..just at a certain medium temperature (i.e. most of the time) and it doesent go away or get louder when i apply the brakes. Anyone had this happen to them?? Should I bust out the belt sander and sand away some of the Ferrodo$?

Re: 9.4" Vented Rotor Upgrade (-camber)

Did you change the calipers too? I know you have to switch calipers when you put vented 9.4s on the Foxes.

you shouldnt have to change the calipers (kelsey-hayes). only the thinner pads and the vented rotors..

What do your pads look like? It they're square-ish and use knock-out pins to secure them then you'll need to replace the calipers. If the pads look similar to a banana (long and somewhat curved), you'll be fine with just pads and rotors.

I would say they are the bannana shaped ones. THey are held in place by those flat metal spring clips.
The pads dont drag enough to slow me down when im coasting in neutral or even with the car jacked up, the wheel spins with minimal pad/rotor contact. Its just once its moving and at a certain temperature.
Is anyone else running Ferrodos? Ive never ran them before.
These are the pads im running with vented rotors

If the pads look similar to the ones in the picture then you'll be fine with a simple swap. You shouldn't have any drag from the rotors - be certain that the wheel bearings are OK since they'd be the only source of play between the rotor and the pad.
I've never used Ferodo pads but have heard both good and bad comments (unlike Metal Masters that have a universally bad reputation).

I had that happen w/ my old 16V GLi. The pads rubbed a little and the sound went about after about a week of driving.

Re: (ncvwnut)

With aggressive pads, it's not unusual to hear a gentle scraping sound as the wheels turn. Normally this goes away after a short while, as the pads bed in. It may be that your pads are just a teeny bit on the thick side and are genuinely dragging. This will cause accelerated wear, until they're no longer too thick, and then you should live happily ever after.
