Please clarify for my 3rd grade brain.

Years ago I bought a complete set of pads for my 2000 LGT wagon.

I now have an 05 Legacy OB wagon.

Dumb question.

Will the pads interchange?

common sense says no.


Quote:
I should note that the caliper bracket, and not the caliper, is what determines pad shape. So while there are a few different pads, in some cases the calipers are the same.

The front rotors will work with the 4pots but the rear rotor is entirely different. The 03 WRX uses a 266x10mm rear rotor and the 2pot rear needs the 290x18mm rotor. No other brackets for the front, the rear on the other hand requires either swapping over the rear backing plate off the newer car(pretty big job) or a 1pot to 2pot adapter correctly locating the the 2pot caliper in space over the rotor and changing the caliper bolt spacing.

The Brembo's have a different thread - so you need them

I am pretty sure the banjo bolts are a differnt length - the lines are basically the same.

You guys all get so hung up on the calipers, rotors, and pads. I want info on the power brake booster. THAT is where most of my problem is. Mushy peddle with poor feedback.

I want to change the Brake booster to one that will not have so much boost to it and so much give. I think the stocker is a 2 stage and I want to go to a single stage like most other cars have.

Dos any one have any info on this?

This is the WRX front rotor. It uses a two piston sliding front caliper or the Subaru fixed 4-pot. The sliding caliper, bracket, and pad were changed in 03 and that's something you need to be aware of when upgrading from RS brakes or purchasing pads. The 4-pots are only on the 06-07 WRX in the US, though they were on many older non-US STis and WRXes (the black calipers with Subaru across them). Generally 16" wheels are required with these brakes but there are some 15" wheels out there that work. Also 16x6.5 Subaru wheels do not clear 4-pots.
Applications:
01 Legacy GT LTD?
02-04 Legacy GT
05-09 Legacy non-gt
01-09 Outback
02+ Impreza WRX (including 08, which uses 2-pots)
03+ Forester
Baja
I have a 98 STI Type R (JDM). It has the black calipers with "Subaru" on them, leading me to believe it has 4pot fronts and 2pot rears... but it has 16x6.5 in wheels (granted the spacing for the front wheels and the calipers is only about 1/8 to 1/4 of an inch).

What I really want to know is will brake pads for an 02-03 WRX work?

no - you'd need USDM 06/07 pads

Doh, missread the part I quoted. Awesome, 06/07 front/rear pads will work. Thank you for the clarification.

Anyone have an update for 2008-2010 WRX upgrade to 06-07 WRX Rear 2-pots?

Looking just at dimensions and info the 2008-2010 WRX doesn't have a backing plate so would you need or be able to use the 2-pot kartboy rear adapter to fit the calipers? For the rotors it looks like we would need the 2001 STi JDM rotors at 290mmx18mm with 190mm parking brake. Has anyone tried this or have any further info?

The 190 mm gravel rotor might work but the height of the drum might be a problem. I know the height of the 08 STi rear drum = different than the earlier one.

It should be bolt on if you use a redrilled 08 STi rear rotor.

I haven't tried this but I think you are on the right track. If it helps, the 290x18mm rotor with 170mm parking brake for the 06-07 is shared with the Legacy GT 05-09 rear brakes, though those use single piston sliders. By extension the 08+ WRX rear brakes share caliper and bracket with the 05-09 Legacy 2.5i. I think that translates to the Gravel rotor being the one to work. But it might need a custom adapter for the 2-pot caliper.

I've also noticed that the '10 LGT appears it may have the gravel rotor stock, there is a Brembo swap in a thread over on Legacygt.com and you can see the stock vented rear rotor has 190mm parking brake hat like the 08+ WRX. It might be 290x18 but not sure yet since the usual parts databases aren't up to date for that new application yet. That might bring the cost of sourcing rotors down if it is true.

I am thinking of doing the gravel rotor(maybe '10 LGT rotor) and LGT rear calipers when I use up my extra rotors and pads at some point in the future, since I already have LGT fronts.

Great info coming in on this, if the rear 2010 LGT is the same as the 08 WRX then it should be the same situation for the brembo's fitting. Would be nice to find a solution for the 2-pot rears from the 06-07 WRX though.

Hmm, I'm possibly looking to swap my '06 STi Brembo's out for a set of '08+ STi Brembo's, is this even possible?
