Loyale 2.7 Turbo Posted November 29, 2015 Share Posted November 29, 2015 Im lookin at slapping some 93 turbo legacy rear vented disk brakes on my wagon... I kindly suggest to "Upgrade" the front brakes as well, otherwise you'll Lost the Balance, and the rears might Lock easily; and that will need a Master Cylinder upgrade as well, because the 13/16" bore one will go to the Floor without providing enough clamping pressure at the Calipers. In my case, the "Upgrade" I did, was to use another (Slightly Bigger) Calipers in my Subaru Rear Discs, in order to have rear Parking Brake, that let me keep everything else, stock. More information about that, here: ~► http://www.ultimatesubaru.org/forum/topic/129779-the-definitive-rear-e-brake-retrofit-solution/ Kind Regards. 1 Quote Link to comment Share on other sites More sharing options...

I was going to go the route of the nissan rears. Which i have aquired but stumbled upon a great deal on the vented turbo legacy rears complete setup. Everything from the brakes to the e brake lever. And yes of course im upgrading the crappy fronts! Ive got gc era sti knuckles and am collecting the parts to upgrade the brakes to wrx brakes. Was going to go the way of the 4 pots up front but decided stock ones will be more than adequate and cheaper for what i can get out of them. I know there is a proportionining valve in the rear, would i need to replace that with a different one to allow different flow? Oh and i also picked up a new larger legacy master cylinder to go along with it all. 1 Quote Link to comment Share on other sites More sharing options...

Loyale 2.7 Turbo Posted November 29, 2015 Share Posted November 29, 2015 yes i remember reading your post a while back. I was going to go the route of the nissan rears.... Now I understand. (But I never used Nissan Rears) The Legacy Master Cylinder is 15/16" isn't it? If so, the Proportioning valve could bear the flow, appropriately. Going further bigger, might require a bigger proportioning valve as well. Kind Regards. Quote Link to comment Share on other sites More sharing options...
wagonist Posted November 29, 2015 Share Posted November 29, 2015 (edited) The easiest way to do this would be to: - get a pair of worn out rear drums (check the spline is ok) - machine these down so that the Legacy disc fits over it snugly & locates (the normal Subaru hub locates the brake rotor via the centre bore) - drill it out for 5 x 100 wheel studs - make a plate that suits the shape of the rear trailing arm where the backing plate bolts on (ie centre bore size, 3 bolt holes) - weld this into the centre of the Legacy backing plate - some in Aus have used the handbrake lever from an 80s Mitsubishi, but scour the junk yards to see what's available - or make up some super long cables with the correct ends (my cables go forward from the factory handle, then loop around on top of the gearbox, go back down the trans tunnel to the rear). I'm using Honda rear calipers on the standard rear discs Edited November 29, 2015 by wagonist 1 Quote Link to comment Share on other sites More sharing options...
mm88swrt Posted November 30, 2015 Author Share Posted November 30, 2015 Im going to be using stock wrx brakes on mine. Way better than the stock ea brakes. The rears will still be a single pot rotor. Just a little bit bigger piston and rotor with the plus of a vented rotor and drum style e brake. The whole braking sytem is being upgraded, not just the rears. Im lookin at putting about 240 to the wheels once tuned and am doing what i can to make sure i can stop good too! I wish i had a build thread. Maybe ill just start one now as a version 4.0 the final draft! 1 Quote Link to comment Share on other sites More sharing options...

I also just snagged a set of 2008 tein super street coilovers with edfc for my car too!!! Quote Link to comment Share on other sites More sharing options...
Loyale 2.7 Turbo Posted November 30, 2015 Share Posted November 30, 2015 Electronic Damping Force Controller on a Loyale will be something New. Yes, it needs a new Build Thread, with a summary of the Previous mods. Good Luck! ... Kind Regards. Quote Link to comment Share on other sites More sharing options...
wagonist Posted December 1, 2015 Share Posted December 1, 2015 If you're going to upgrade the brakes, I'd replace the master cylinder & booster also. They are bigger. One of my cars I bought converted to WRX running gear had this. The Impreza booster was a tight fit to get in (have no idea about if this is possible on LHD). You have to remember also that Legacys, Imprezas, etc have their braking circuits split front/rear, not diagonally. So also get the matching proportioning valve (which on RHD models sits close to the master cylinder anyway in the engine bay) & fit that. You'll need to re-route the brake lines. Mine still had the rear proportioning valve fitted under the floor, but personally, I'd get some fittings & remove it. Quote Link to comment Share on other sites More sharing options...
