92turbooooo Posted July 1, 2012 Share Posted July 1, 2012 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 Link to comment Share on other sites More sharing options...
USLiberty Posted July 1, 2012 Share Posted July 1, 2012 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. Link to comment Share on other sites More sharing options...
urfsin Posted July 1, 2012 Share Posted July 1, 2012 Any reason not to "big" w/ LGT brakes instead? Slide It Sideways Link to comment Share on other sites More sharing options...
Legacy Wagon Posted July 2, 2012 Share Posted July 2, 2012 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.

monkeyposeur Posted July 2, 2012 Share Posted July 2, 2012 camromcamera did a great write up on the brake swap he did on his second gen: http://legacygt.com/forums/showthread.php/2nd-gen-lgt-brake-upgrades-wrx-front-and-h6-rear-154702.html The stock rims won't clear the wrx brakes iirc.

sqc151 Posted July 2, 2012 Share Posted July 2, 2012 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. http://legacygt.com/forums/showthread.php/sqc151s-white-night-183274.html 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.

enzotheracer Posted July 3, 2012 Author Share Posted July 3, 2012 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.

Legacy Wagon Posted July 3, 2012 Share Posted July 3, 2012 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 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. Link to comment Share on other sites More sharing options...
sqc151 Posted July 3, 2012 Share Posted July 3, 2012 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.

enzotheracer Posted July 3, 2012 Author Share Posted July 3, 2012 It's not an as. It's a 91 fwd wagon Link to comment Share on other sites More sharing options...
jamal Posted July 3, 2012 Share Posted July 3, 2012 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. Any reason not to "big" w/ LGT brakes instead? wheel clearance and brake bias come to mind. Link to comment Share on other sites More sharing options...
sqc151 Posted July 3, 2012 Share Posted July 3, 2012 It's not an as. It's a 91 fwd wagon 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. wheel clearance and brake bias come to mind. 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.

joelwatts Posted July 3, 2012 Share Posted July 3, 2012 i have an fwd svx master cylinder if anyone needs it. pm me for details I'm a native of South Carolina. I am a dying breed. Link to comment Share on other sites More sharing options...
jamal Posted July 3, 2012 Share Posted July 3, 2012 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. It does. The 91 fwd wagon has a 1-pot and 260mm front rotor. Going to a wrx sized 2-pot is a 30% increase in brake torque. Going to the 05+ LGT brakes is a 40% increase. You might as well just take the rear brakes off because they're not doing anything. Upgrading RS/2nd gen LGT 2-pots to wrx size is a much smaller change, but when you move the bias forward you are having the rears do less work, and that will lengthen stopping distances. On a non-abs car it also means it'll be much easier to lock up the fronts. Link to comment Share on other sites More sharing options...
sqc151 Posted July 3, 2012 Share Posted July 3, 2012 thats why i said if there still 2pots it doesnt make much of a difference. and the rears are probly drums... LOL Link to comment Share on other sites More sharing options...
jamal Posted July 4, 2012 Share Posted July 4, 2012 All 1st gen legacys came with rear discs (in the US anyway- there might be some super base model euro/jdm cars with drums but I kind of doubt it). Link to comment Share on other sites More sharing options...
enzotheracer Posted July 4, 2012 Author Share Posted July 4, 2012 i know the bias will change. i am aware of that. i was going to do the rears but i did not have the funds to do so. so i will have to wait to do the h6 swap when they get worn down again. i have the funds to take care of the fronts now. i know they have a much higher chance of locking up due to the much increase in brake force and surface area. i do appreciate the help. this all really helped me.

Legacy Wagon Posted July 5, 2012 Share Posted July 5, 2012 Honestly, once you get accustomed to the braking point before it locks up you shouldnt have to worry about locking them up again. Link to comment Share on other sites More sharing options...
