Depends on what braking performance you want, you can ask 10 people and get 10 different recommendations.

Not sure if this has been addressed, but maybe someone here will know. Is there any difference in the parking brake cable system between the 02-05 wrx and the 06-07 wrx? I'm aware of the rotor and shoes being different sizes. I'm intending to swap complete rear knuckles from an 06 with hub/2pot/rotors/pads/parking brake, but I'm just curious if my existing parking brake cable assembly will be compatible. Thanks in advance.

If it is a sedan, Subaru lists parking brake cables as follows:

L: 1998 through 2004
R: 1998 through 2004

L: 2005 through 2007
R: 2005 through 2007

Thanks for the input, I appreciate it. The question remains despite that, however. They may be different part numbers, but it might not be of any consequence. To reiterate, I just wanna know if the 06 wrx knuckle/brake assembly will accept my 04 wrx parking brake cable. Hopefully someone has experience with this!

Has anyone come up with a bracket or replacement disc to allow the use of 08+ sti rear brakes on a GC/GD?

Thank you for compiling the data.

However, as a subanoob, I have some difficulty interpreting exactly where to pull dimensions from or what different shapes are. I gather that H4 and H6 are distinctive, but without a pictorial example, I can't figure out what I have.

(04 legacy that prior owner claims to have put Forester discs in the back.)
I'm happy with the performance, but the pads are bad enough that they have scored the discs. I just need to be sure what caliper body I have and what discs and pads to get.

So far, disc comes out to 9mm thick, so that means it started at 10, and is roughly 30cm. Looks like I need to pull the disc and get a more precise measurement, as there are 3 possible options on the first post:

1: 286x10mm which has appeared on a forester,
2: 390x10mm as found on the 00-04 legacy with the H6 caliper
3: 274x10 as found on the 2014+ Forester 2.5i

Most likely it is one of the top two.

Pic of the caliper from the back- in case it is visually obvious or the casting marks help to identify. For all I know, they just track what shift they were made on.
https://i.imgur.com/XMUPBX0.jpg

This guide is great for pulling dimensions, but hard to know what points the dimensions go to. i.e. If I am measuring the parking brake, what portion of it am I measuring?

I mention that, since it seems to be the distinguishing factor.

If you can clear up this stupid question for me, I would greatly appreciate it. I think pictures or drawings showing the dimension types and the basic pad shapes would help others reading the guide too.

It seems I probably have the standard parts. Maybe. Help.

"290x10mm
This is well known as the H6 rear rotor. The Legacy caliper is the same as most other 99-07 1-pot Subaru calipers so you can upsize to this rotor simply by purchasing the brackets and correct pads.
The "H6" bracket is part number 26625AE000. It uses pad shape D770
Applications:
00-04 Legacy/Outback non-brighton
SVX (5x114.3, 190mm parking brake)
Ver5 STI type-RA (5x100, 190mm parking brake)"


Mine is 290x10mm with the 170 mm parking brake. What is not clear to me is whether this disc is 170mm in the version I highlighted in blue, or whether they are all 190mm. If the latter is true, then my disc is not listed above.
Can anyone clarify this for me?



For future readers who like me are not very familiar with Subaru rear brakes, some explanation may be helpful. I'll post the pictures which would have helped me to understand earlier.

Subaru brake discs for the rear are a combination of a drum brake inset into a disc brake.

The parking brake is a drum brake, and the disc brake goes around it.

So in my case, the internal drum is 170 mm nominal internal diameter. 171 is the rated max wear, but it seems doubtful that many people wear out the drum portion before the disc.

See pictures:

A picture of the assembled caliper from the side is pretty useful, all those stamping and stuff on it not as much.

BUT, from that pad I can tell you it's shape d770, which is for the 02 wrx and 00-04 legacy and some other cars after about 1998.

The forester rotors you mentioned won't actually even fit on your car. New stuff from the 08+ multi-link design has a different offset from the hat to rotor.

So anyway your brakes are just regular 00-04 Legacy parts. There's no difference between H4 and H6 rear brakes. Fronts, there are two sizes depending on year and trim.

Thanks very much Jamal. People like you make the world a better place. I love that no matter what the topic, the hivemind is sure to supply a guy who knows what you need to know, and took the time to do a decent write up.

I'm unlikely every to be able to repay you with automotive knowledge. But if you ever have old motorcycle or weird firearm troubleshooting questions I might help you on the appropriate forums. (I suppose I wrote the equivalent post about gas pressure dynamics in mag fed shotguns.) Or I suppose legal questions, but I tend not to do general posts on law.

Might I suggest a small edit to your original post? Under the H6, could you list that the legacy standard discs are 170mm parking?
like so.

EDIT - In case anyone needs to replace one of the caliper-to-bracket bolts (these ones seem particularly prone to seizing because of galvanic corrosion) on the Version 1 KNS rear brake adapters, I just got the specs from KNS - they are M10x1.25x35mm SHCS.

I want to rally a 2012 Subaru Hatch STI C spec with 18 inch rims. I have to go down to 15inch to fit rally tyres. Present brakes are gold Brembo.
Does anyone know what brakes will fit this car and take 15 inch rims? Preferably 4 pot front.

Default 02-04 Outback brakes on 00 Forester / H6 WRX?

I have a 2000 Forester S. I found this kit for an 02-04 Outback.

POWER STOP KCOE2751
https://www.rockauto.com/en/moreinfo...=7485524&jsn=5

It appears it has the H6 rears and WRX fronts, looking at the rotor sizes, 11.4in rear and 11.6in front. Can someone please confirm? I'm pretty sure the calipers/rotors will bolt to my car but need to know if my brake hoses will fit the Outback calipers properly. Does anyone have any experience with the Power Stop brand? Is $420 a good deal for complete new brakes of this brand or should I go a different route?

I've priced H6 brackets, pads and rotors with 02 WRX brackets, pads and rotors and it comes to around $300 for better brand name stuff. Cardone brackets, coated centric rotors and Akebono pads.

Any insight or direction would be appreciated.

coincidentally I was just on your website, I see the SS brake lines under the 2019 STI option, 2020 wasn't an option. Will all the 2019 parts fit the 2020's? I'm wondering if they have the Stoptech pads for the 6pot's.

"Old and new stuff will not interchange because the offset between the rotor hat and caliper changed."

I'm a little confused with the sti rear brembo specs, the 316x20 5x100 and 5x114 old & new. All the links show 59mm between the mounting face of the rotor to the rear braking surface. So it shows the new and old having the same offset. What am I missing?

I think I just answered my own question. The DBA dual drilled rotors work for any 04+ sti. So it's not the offset of the rotor that changed in 08, its the offset of the caliper itself. Now I just need to find the difference in offset on the caliper from 04-07 and 08+ rear brembo.

I'm researching what it would take to mount 08+ rear brembos on an 05 outback. The 04 rotor will work if I get the DBA one with the 170mm parking brake. Then it looks like I need to machine some of the mating surface from the brembo to align it to the rotor. Someone did this on a Tribeca, the machined off 8mm and it worked. I just don't know if it's the same here.

(Yes I know the bracket exists for the 04-07, but I can get a killer deal on 08+ and I like the larger piston size. But I might end up just sourcing a set from 04-07)

Well except the offset of the rotor did change in 2008 but anyway.

On a GD WRX the tabs of the 08+ rear caliper will not fit down in between the rotor and backing plate so you would have to at a minimum machine the caliper tabs. I canít recall if I used a GD or GR rear STI disc. It might have been an adapter rotor though.

In an earlier version of the first post I had all the rear rotor sizes grouped together and not split between "old" and "new" and it appears I just don't have the correct rotor drawing linked for the 08 sti rotor.

And yeah, 08 brembo on a non 2-pot rear backing plate is something that almost works, as in the holes at least line up.

Here is centric's drawing for the 08-17 rear

You're right, of course, sorry about that. When I looked up rotor compatibility on a site I was looking at, they said the DBA dual drilled 04 sti rotor would fit 04-17, that is just wrong. the 04-07 is a different offset to the 08+.

So apparently the early Tribeca's had the same offset as the 04-07 in the rear. I found someone that got the 08 brembo to work, they machined 8mm off the back of the 08+ brembo and it cleared and aligned properly. This still left about 13mm of thread that the bolt could grab. Apparently they haven't had any issues, though this seems questionable lol.

Thank you for that!

Yeah, as I mentioned, the problem is the 05 outback has the 170mm parking brake, the 08+ brembo physically bolts up no problem, but the 08+ rotor has 190mm ebrake. So I have 2 options from my research. Buy the conversion brake shoes that work with the 190mm ebrake on the 08+ sti rotors or have the caliper tabs machined to change the offset and then use the WRX upgrade rotor.

Pretty much 'yep' to all.

I have gotten the "Fit the GR rear on the GD" for a bit now as goldies become oldies - and with some significant creativity it can be done.

You can machine down your caliper - and I might even machine down mine. But as a business I just can't tell YOU to machine yours. You can imagine how that might end up.

If you like the fabbing stuff - do the GR's somehow. If you just want them on there - trade them for some old rears.

My RHD 2002 WRX Wagon which actually has a chasis date on it of 2000 appears to use the D929 pads but the front rotor is only 276-278mm. I'm having a hard time finding which rotor it actually needs. Looks like maybe the 98+ RS rotor?

Edit: I figured this out, there was a change in brakes used on the 2002 WRX in August, 2002. So you need the D929 pads and a 278mm rotor if you have one of the early cars and don't want to replace calipers.
