I didn't have brakecleaner at the time I installed my rotors and pads (Racing Brake and Hawk HPS), so I wiped off the excessive oil using paper towl and burned the remaining oil on the rotor. Is it still necessary to clean it using brakecleaner even though I have mroe than 500miles on the rotors?

Brake performance is TERRIBLE compared to stock. Current setup:
Front: Racing Brake slotted rotors, Hawk HPS
Rear: New Stock rotors , Hawk HPS

I bedded in the brakes using Stoptech method. about 5-6 times of 60-5mps braking. I can NEVER trigger ABS on my car anymore on a dry tarmac. My tires are Pirelli Nero M+S.

Once your new pads have been contaminated with the machining oil that the rotors have on them AND you've heat cycled the pad with that oil, you need to buy a new set!

I also agree that your brake bias may be out of whack. If you think about it your RS's brake bias is for smaller front rotors and same as WRX sized rear rotors. Just putting on WRX sized rotors up front does not mean that you get better stopping. Your proportioning valve has not changed so you have shifted more bias to the front than stock by using the larger WRX sized rotors. your stock brakes would have given you better braking than you have right now. Going with the H6 rear rotor will help bring that brake bias rearward and hopefully closer to at least your stock brake bias.

So my rotors are OK, but only pads need to be replaced? Also, once the pad is contaminated, it doesn't matter how much I wear it out (even by half of the thickness), it's still contaminated?

Thanks for your input

yes, you need new brake pads, you should even use brake cleaner on the pads once you get them, and be sure not to touch the brake pad surface at all. brake pads are extremely porous and will absorb any kind of oil deep under the surface, think of a flywheel with an oil coating, then installing a brand new clutch onto that flywheel, same effect. if anything, get the H6 upgrade or use really strong brake pads in back , and stock ones up front.

i don't buy that the pads are irrevocably ruined the second any oil touches them.

does that mean i can cause thousands of dollars worth of damage while walking through a parking lot with a can of pb blaster? my boss IS an a-hole... maybe i should go spray his pads so that he flies right off the road!

the pads get HOT folks. hot enough to burn off petroleum distillates, that's for sure.

Precisely. That was so obvious to me that I didn't even bother replying.
My brakes sucked horribly after I installed them because I didn't get all the oil off at first. A couple dozen smokey stops afterwards and now they work GREAT.

I have this exact setup (RB rotors, HPS). Racingbrake has their own procedure which I followed to the dot, and my brake performance has been dramatically increased...

After install, 10 X 30-10 with 15 seconds between each run. During this period, the brakes will smoke and smell like poop...

After the 30-10, wait a while and do 5X 50-10, again waiting 15 seconds between each run. The brakes will again smoke but should feel significantly better. If you do not do this, the brakes will feel like trash for a long time...

How would you go about finding out if this is possible or not? I don't imagine a dealership would know...
I saw North Ursalia's write up, but he used the actual LGT rear brake kit, and I don't have the money for that...
If you look closer on the write-up on Brian's site, it says to contact himself or Mike if you have any questions. Brian & Mike are both good people to talk to and I'm sure they would help you. They can get you the parts. BTW, they work at a Subaru dealership.

I drive an '05 Outback Sport. Now, would this H6 conversion help my braking? I believe my stock brakes are the same as a 2.5RS, so, in this case, my car would fit the bill for getting better braking power by doing this H6 conversion, correct?

If I were to go to a dealer, what car would I tell them I need these parts from? I would be able to use my stock calipers, but I would need new carriers (brackets), and new rotors? Is that it? Agaion, what car are these off fom? Thanks. I see this mentioned everywhere, but, nowhere is there actually an explaination to it (that I can find at least).
