my 06 wrx has stock front brake pads on it. i am changing them to hawk hps and my question is do i need to replace the shims and pin retainer springs as well, new ones did not come with the pads?
what brake fluid upgrade is compatable with stock fluid when changing brake fluid?
when resurfacing youe rotors what is the min thickness before replacement and i heard after cutting the rotor you re-cut the rotor in reverse("reverse swirll") to gain better pad seating?
any help would be great.. im a noob appreciate everything
Best of luck to you
As for resurfacing rotors you may be better off to just replace them with brembo blanks or oem.
Sometimes after resurfacing them they tend to warp much quicker and you'll end up putting new ones on sooner then you hoped.

1 - You should be fine re-using the shims and retaining springs. I don't see that causing any problems. If they "HAD" to be changed every time, I would think that they would come in the packaging, especially with HAWK pads.
2 - If you want to "top off" the master cylinder, use the stock fluid if that is what is in your system already. If you are talking about a flush, use whatever you want; DOT 3, DOT 4, MOTUL, what's your poison. Just do not put something less than DOT 3 in, as it may cause problems with the system.
3 - I have never heard of cutting the rotors in reverse... I don't think I would even begin to try that...
Hope that helps a little bit, if not, sorry. And about the min turn thickness, it should be stamped on the hub somewhere, either inside the mount hub, or on the outside, I think that is a mandatory regulation that is followed. But I think that I would just replace the rotors.

Yes, you can reuse your shims.... just clean them well.
You shouldn't need new fluid. In fact, when you compress the brake pistons back inside the calipers to accomodate the thickness of the new pads, your brake fluid level should go UP in your resevoir.
However... a flush is a good thing. I like ATE Super blue racing fluid..... withstands a LOT of heat, and it is not terribly expensive. Plus, you can tell when the system is clear, because all the red fluid is gone, and tuned dark blue. A $15-$20 can is plenty enough to flush the whole car.
The minimum allowable tolerances for the rotor thickness is stamped on the backside of the rotor. I don't remember off hand what they were.... but I do remember having my stock rotors turned, and the tech "almost" wouldn't do it for me because he was afraid it would go past the allowable thickness.
He did... and they were fine..... but I only had a slight wobble before turning them.
If your car is shaking bad.... I can tell that it will take more cutting to get them straight than what the rotors will allow..... so just replace them if that is the case.

Like said before hand, don't worry about anything besides just the pads.
If you're doing a fluid flush... do lines at the same time. It's the smart way to go about things.
Unless you drive extremely hard, it's very difficult to actually warp the metal it's self on your rotors. In general brake vibration with a WRX is caused only from deposits from the pads. So turning the rotors (WITHIN SPEC) should get rid of any brake vibration.
