wrx front brakes.
 
wanting to do the front wrx brake swap. was wondering if any one has already done it and could tell me what i need to buy and if there is any thing important that i need to know before starting.

Well, for the 02-05 wrx front brakes (the cheaper one) you need.

02-05 wrx front calipers and caliper brackets

02-07 wrx rotors

Brake pads to mach the calipers. I say this because the pads on the 02 wrx are different from 03-05. Depending on the condition of your old brakes and if you know what your doing, the swap should take a couple hours. I've seen it done in about 20 mins though ;)

How much of a difference was it when you upgraded from stock ss brakes to the wrx brakes? Did you swap the rear also? I've seen someone use mitsu evo brembo calipers easily modified to bolt on with LGT spec b rotorsThey're cheaper and bigger than sti brakes. Thing is you want to upgrade the rear accordingly so brake balance is unaffected, not sure if evo brakes will also swap to the rear.

Any reason not to "big" w/ LGT brakes instead?

I've found that in my car, AWD, auto, non-abs,
it decided not to fill the WRX calipers very quickly.
Wasn't really an upgrade at all for me :/ If you have
ABS it has a larger bore Master Cylinder that'll fill the
front brakes much quicker. If you have a non-ABS you'll
need the larger 1-1/16th bore MC from the FWD SVX. I
haven't done that part yet, but yeah, the swap's easy as
crap, but the freakin brake bleed is always the annoying
part. That's part of the reason I haven't swapped them to
my 5spd wagon with ABS. I wish I would have just waited
to put them on that car instead haha

Now, will the stock rims clear WRX brakes? I have the
WRX rims on mine so I'm not sure how stock would fare.

camromcamera did a great write up on the brake swap he did on his second gen: http://legacygt.com/forums/showthrea...ar-154702.html

The stock rims won't clear the wrx brakes iirc.

true^^^

i have wrx front brakes right now. takes about 20 mins. and replacing the lines with wrx does nothing. the pedal will feel "weird" for a week or 2 and then be back to normal. mine did anyway... i have the wrx brake booster, just waiting to get 4pot fronts.

my build thread will show you what i did.

our rear brakes are vented vs wrx's non vented. so i would leave the rear alone unless u go wider in disc size. the stock rear brakes are just fine.

So should I swap my turbo abs master cylinder into my non abs car with turbo brakes swapped already? Good to know about the different bore size, I had no idea it was different.

i want to do a cheaper big brake up grade. as camroncamera stated that the brakes are to small for this car, i do as well agree. what i need to know is what year wrx i need to use, if i can use the stock brake hoses and if there is anything else i need. i just want to order everything once and get it all done in one sitting.

I dont think you can. The ABS has 4 ports and the
non-abs has 2. That's why you'd have to get one
from a 94-96 (I think) FWD SVX because they were
the only ones with wider bore with 2 ports. It will/
should have 1-1/16th stamped on the side of the
larger opening MC's.

Now did you notice a difference when you swapped
out the brakes or was it negligible? Mine was overall
unimpressive. I need to get that new MC some day.

sqc151 07-03-2012 12:22 PM

the difference in SS and WRX are brakes are minimal cause there both 2pots with a slightly different size rotor. if you want to feel a difference, u need to get 4/2pot brakes or brembos.

It's not an as. It's a 91 fwd wagon

On my old 1st gen I did wrx front and h6 rear brakes. Even with good pads there was quite a bit of pedal travel due to all the extra piston surface area. My 2nd gen has the bigger MC and the brakes are much better. Like was mentioned, the FWD SVX was the only car that came with a 1 1/16th MC and no ABS so that is the one you want to get (Centric part 130.57019).

You should also know that just putting on WRX front brakes is not a great thing because it moves the brake bias really far forward. To balance it back out you would want to get the 00-04 Legacy "H6" brakes. They use the same caliper as an 00-07 impreza but a taller bracket and bigger rotor.

wheel clearance and brake bias come to mind.

i was refering to the post above.
honestly, youd be fine just changing the front brakes to wrx cause your fwd and have a much smaller rotor diameter than the SS.

if there still 2pots in front and 1pot in rear. the slight rotor size wont make a difference. i have wrx brakes in front and honestly, nothing changed.

like i said above if anyone is reading this, if u want a noticeable difference, then spend the 1000 bucks on the wrx 4/2pot set up.

i have an fwd svx master cylinder if anyone needs it. pm me for details :)
