PoorManzImpreza Posted January 29, 2005 Share Posted January 29, 2005 Well I thought its about time I posted about this..I recently upgraded to rear discs on my wagon and after the usual pains of bleeding, I had better overall stopping power but my brake pedal felt well..nasty..lots of pedal travel that it never needed and vagueness..bleh but it stopped well enough..So while getting some parts at the dealer I looked up in the legacy parts book to see what the biggest MC ofered was hmmm 1 1/16" but only on ABS cars..so only two brake lines hookin up...scratch that..1" nice.. non ABS cars, even had a three line one for 5 speed legacys with a hill holder.. perfect! So I asked if I could take a look at a brand new ea82 MC and compare it to a brand new legacy MC..and it was a perfect match to the ea82 mount.. So the bad news.. "Oh we don't have the 1" in stock, biggest is 15/16".." bleh now get this guys the 15/16" legacy MC was cheaper than our ea82 MC!! that might only be true down here but who knows... Second bad news "We only got the MC for automatic cars in stock.." hmmm so only four line hook up no three line..but there I am with xmas gift money burning a hole in my wallet so I go ahead and buy it.. Mount and connection issues: 1. Problem: The break fluid level sender has a diff connector than our ea82 cars expect. Solution: I can cut off legacy connector strip wires and splice on ea82 connector..hmm even easier I can remove the legacy sending unit from the bottom of the fluid reservoir and slip the ea82 sending unit in its place..perfect fit problem solved. 2. Problem: The extra brake line fitting on the bottom..I simply used an extra M10x1mm bolt I had knocking around cut it so its shank was about 6mm long then crabbed a copper washer off of a front caliper banjo bolt cleaned it up and then bolted it onto the MC with a little teflon sealant just to be safe..problem solved. the rest of the installation was common to any ea82 manual transmission car. WOW! Firm high brake pedal! more effort yes but the car stops SO much better this made a huge difference to how my car stops and how the pedal feels..For any person out there with rear discs I must inform you that as far as I'm concerned this is now a manditory modification..and get this it seemed, and I admit this isn't objective, that it was easier to bleed!

85Sub4WD Posted January 29, 2005 Share Posted January 29, 2005 I think if you had replaced the porportioning valve you would have had the same/similar result, but I still like the mod, and may do it myself after I put rear discs on. Link to comment Share on other sites More sharing options...

Caboobaroo Posted July 29, 2008 Share Posted July 29, 2008 I'm looking into it as well since my MC is leaking and my rear brakes aren't working as good as they should. Unfortunatly for me, I have a 4 port MC instead of 3 since my car never came with a hill holder due to it originally being an automatic. So maybe I'll look them up in the computer at work and call around to a few places since I need one bad:-\ Link to comment Share on other sites More sharing options...
PoorManzImpreza Posted July 29, 2008 Author Share Posted July 29, 2008 The MC I used was a 4 port, just keep in mind that the P/N I posted is for a RHD car, 26401AA401 is the P/N for LHD auto 1" MC Link to comment Share on other sites More sharing options...
idosubaru Posted July 29, 2008 Share Posted July 29, 2008 how much of the improvement do we contribute to the larger MC verses the replacement of a 15 year old part and changing the fluid? the 15 year old MC probably wasn't performing like it was when new and the brake fluid was changed as well when installing the new MC. i wonder if replacing the 15 year old MC and giving the system new fluid might have helped more than having a larger MC? what is the stock EA82 size?

PoorManzImpreza Posted July 30, 2008 Author Share Posted July 30, 2008 I was replacing a few months old ea82 MC with the brand new legacy unit... I rebuild the front calipers and rear wheel cylinders and replaced the MC with a stock one, this was fine. I then did a rear disc upgrade, again with rebuild calipers and it stopped much better but as I stated I didn't like the feel, hence the legacy upgrade. both bleed normally and then with the engine on under power assist as I've found this works best for our ea82 cars. ea82 MC size: 13/16" with a 1" section on the end towards the brake booster..
