now with wrx brake love!!

Default using 05' wrx brake master on an non-abs car

so when i got all my brake stuff i got the master cylinder for like $20, i was worried about whether the set up was the same or not and it turns out that it isnt. my L master has three lines going to it where as the rex's has two. i'm guessing that has something to do with the fact that the wrx has abs and therefore the abs motor thingy so it splits into front and rear from there. any ideas on how to get this to work or am i'm going need to get the little distribution block thingy from the wrx? thanks guys

might just want to use the L MC. they should be the same diameter.

there are 3 types of MCs: 2 port: ABS 3and 4 port: non-abs

sometimes they need the corresponding booster too.

pretty sure everything is 1" unless its an STi or SVX, which have 1 1/16"

they should say on the MC what it is.

some L has 15/16. honestly, you dont need a bigger bore, you'd just want it for the feel. so get some better skills :P

i never quite understand what you are saying, i guess i'm not cool enough to understand moose jargon. anyway the rex's is actually 1 1/16" and yes, i do want it for the feel. i love a really hard pedal feel. but it looks like it would be too hard to do. the thing is that i could get the booster and all the other stuff too. do you guys think that it would be worth it to get all that stuff and run it without the abs hooked up?

or if yours is 15/16", you could go up to a 3 port legacy one (if theyre 1", dont remember, i think some are).

you could split the 2 port i guess, i mean, the fronts are split on the 3 port. custom lines for that, thats all.

IMHO, the calipers make more of a difference in feel. and bleed it really, really good, that refreshes the feel quite a bit sometimes.

smaller bore = less force to lock up tires. downsides, you will blow through more pedal before stuff happens - braking happens at near the end of the stroke. this hard feel thing is not really an issue, if you run a bigger MC you have to exert more force on it to lock the brakes, and therefore you "feel" like you are doing more work and its "harder".

i.e. - honda civic CX has great brakes stock but it does not stop. my car with GDB brembo's all around and a 1" bore MC has blow through pedal feel for the first half, and rock hard the 2nd half. and yes, it does stop. solid feel is gained by proper setup of bleeding and calipers (lines at limit), not by MC. you tune the MC because your right foot dosnt have the sensitivity to modulate a easier lockup, OR becuase you simply like to start braking earlier in the pedal stroke and you are too lazy/ignorant to adjust the MC shaft length to suit that, or cant get it the way you like it.

there are 2 issues at hand, desire for a "feel" and swapping parts simply to compensate for a lack of tecnique. if its the technique thats lacking, improving will make faster lap times, parts dosnt make faster lap times.

Was gonna do this to my brighton w/ 15/16 MC and put in a legacy turbo one 1 1/16 when I did my swap. not worth the trouble to go from 2 port to 4 port, put in stainless lines and the legacy turbo calipers and my brakes work awesome now.

exactally. the caliper change makes much more an impact on "feel". stainless lines are more for bling and peace of mind than feel- yes i have them, and yes they are a ripoff at $100, but at least i know im not running 13 year old rubber lines. mmm. delicious.

i may prefer rubber line feel. but ill be one to say that my right foot and the brake pedal are very good friends.
