Hey Charley,

Sooooo you lost coolant. . . but ya gained a screwdriver!
Can't WAIT to see the 'Hero Cam' footage!!!

Aside from all that -- how are the new seats? I mean, besides a bit 'dirty', perhaps!

At least YOU'RE still here!

Damm Charley you got mad brake rotor skills!!!

But I don't think you have taken off the rotors since you got the car right?

I think you found the problem..... (mental not to self, never-ever install rotors backwards)

Yeah those seats are still needing some modification. I have a little fabricating in mind to drop them down a few inches, it's a little tough to hang in, while leaning over the center console to make room for the helmet.

Right. But if I had, I would still lie. No way I could live it down if I did it twice.

"There is something about the outside of a 928, that's good for the inside of a man."

Pseudo-Corollary:

"There's something about backwards brake rotors on a 928 thats BAD for the coolant system!"

I'm also coming down with Renaloctilitis AKA as a $hitty outlook on life, and your not helping matters.

Easy Fix, Chuckles --

Seems like you just need to consult a doc... and have a blonde help you with your brakes!

Hmmmm. I wonder which dummy did that?

So I hope I'm right in assuming the pads should follow the rotors and the calipers can stay where they are.

The calipers need to stay where they are. Since the pads are bedded in, I would move them with the rotors, keeping on the same sides of the rotors.

I gotta admit that when I first looked at the curved vane rotors my 1st thought was to face them forward to "catch" more air..... glad I didn't try it...& no brake problems for me....well other than a lake of "stones" to take sharky out of the 2nd 1/2 of the day!! :>)

Well, i guess it does matter then.

maybe if you had the 14" rotors of the mercedes it wouldnt.

either way, if you guys buy new rotors and pagid orange pads, they are great on the street and dont squeak. (if you bed them on the track its even better)

So I swapped the rotors, with pads in same orientation to matching rotor, flushed the fluid system and replaced with Superblue. The pads looked good, at least 70% life left.

Now, the fronts lock up much sooner than the rears, and one or the other front, locks up first. On one application the right front locks first and on the next application the left front will lock first.

I have lot's of pedal. I can really smell burnt pad after two or three hard stops.

Do yourself (and anyone else here) a favor. buy some Pagid orange pads. if your rotors are in good shape, (no grooves, not warped, and no lips) , install the new pads and be done with it. Street pads cannot handle a fast moving 928 at thunderhill. you will drive yourself crazy trying to make the car work properly. Bed them in at the track. (2-3 laps making them stink, and smoke ) and let them cool for a few min while driving 2 laps, and then hit them again)
after this, the orange paint shoudl be gone and they are awesome for the life of the pad. no smell, no spungie pedal, no fade!

do it any other way, and you are going against a proven way!

Ive got 93 race days, 10s of thousands of street miles and have no squeaking and brakes that can keep up with most any car out there.

Thanks Mark. Are you suggesting these pads for all four corners or just fronts. If it's just fronts, wouldn't that exaggerate the front first lockup?
