#3132 of 8644 Re Rotors Update

I suspect that may be what will happen to me too, next warping after warranty expires but may just sneak in under the 36 months. Rear rotors on my 2003 Legacy Wagon were also more warped than the fronts (going by the amount machined off) and wear on the pads twice the front wear. Advised by service manager this they see this often on Subarus but first time I have seen rears wearing this much faster than fronts in 40 years of driving (and maintaining).
No complaints, other than minor quirks, after 30K km on the Legacy just disappointed that I can not justify a change to the 2005 for quite a time!

My brother in law and I each had Loyale wagons. Mine was FWD and his "on-demand 4WD". He hardly ever engaged the 4WD and we got the same gas mileage. I don't think weight is the only reason. I think it takes more gas to run more wheels. My brother in law still has that 92 Loyale with over 250K on it!
Totally different scenario. On the part-time 4wd units that were produced in those years they were designed to be driven on-road in FWD (you can't drive em on-road in 4wd) and when they disengaged the rear wheels it is physically and totally disconnected, unlike with the viscous coupling of the MT AWD system or the electronic AWD system found on the automatics.

I've never seen rotors get warped on subies EVER. I've seen pad transfer that creates hills and valleys but never the rotor iteself warped.

Saw your previous post about pad transfer and if I wasn't still in warranty would have given it a try. My question is, if Subaru rotors do not warp why are Subaru paying for either machining or rotor replacement under warranty. The pad refacing would be much cheaper for them.
Living in a fairly hilly (even mountainous area) have never had warping problems previously except on a full size Ford wagon years ago. Dealer blames over heating due to riding brakes downhill but on my wife's Acuras over the last 14 years (who never shifts down going downhill) no problems. What I have noticed with the Legacy is that the rotors pick up surface rust much quicker, and in greater volume, than our other vehicles (Honda, Acura, Mazda, VW). Could this be something that causes the pad transfer / warping?

I called my case into the 800 Subaru number. They took my details down (you'll be able to find my file, I'm sure, using my name: M. Crair, if not, please tell me). Subaru also told me to first try and handle the situation directly with the dealer. If the dealer did not provide 'satisfactory' relief, then I should contact Subaru again, and they would try to intervene.
I'm still without my car...though the dealer now says it is a problem with the clutch hydraulics ('master cylinder'), instead of the clutch itself. I hope they are right this time.
The question remains, however, how much am I supposed to pay for these supposed 'repairs'?
#3137 of 8644 Hi Mike - thanks for the help finding your case.

I just sent a note to Petra and her Manager asking for a bit more intervention. I'm sure you'll be happy as both are very dedicated to our customers. Once again - I'm sorry.

Not sure, but it could be the pad material is poorly matched with the rotor compound. I know for instance the DBA rotors that were sold with wilwood 4-pot brakes to a lot of WRX owners back in '02-03 have a similar problem. The pad material was not matched up well with the rotors and there was a lot of pad transfer causing shaking etc. In fact right now i'm in the process of tracking down the correct pads for the wilwood calipers for a customer who is ditching the DBAs and putting on some of our racingbrake.com rotors.
My guess on the dealer replacing is that they don't know about the pad transfer and figures hey if FHI is gonna pay us to do a resurface or replace, might as well do it. Or the usual "the book says to do XYZ, so we are doing that" instead of what may be more correct.

Mine were definitely warped. I was getting increasing vibration braking at high speeds.
Retorqued the lug nuts this morning. Did a search of posts and it looks like 55 - 75 ft-lbs was the acceptable range. I went for 65. Someone please correct me if the setting is wrong for the alloy wheels on the LL Bean model. I did notice at least one of the lugs on each wheel was beyond the torque of the others.

Forget the viscous coupling, FWD fuse does not work on MT.
The best I understand, in AT AWD, when you insert the FWD fuse, the rear wheels ARE "physically and totally disconnected". The fuse fully activates the duty solenoid C which drops ATF pressue from the center differential and the cluch pack disengages the rear wheels.
I could be wrong, so please correct me.

Yeah, the ones on my 00 and 02 Outback were warped too. I actually saw the feeler gauge bouncing around on the rotors of my 02 when they were diagnosing it.
