hey guys i need some help here, i just finished putting my 5 lug r brakes on my eg when i was done the brakes dont seem to stop close to what they should. the car is a stock si n when i press the pedal it seems to fade down. n on my opinion it dont stop no better if not worse then the stock brakes. i know they should stop dang good too, so my question is what parts do i need to get it to stop good?? i took everything off a 98 spec R n took the porpotion valve n booster n master cylinder but everything seems to be different. so their just laying in my garage, so if u guys have any suggestions please help me out!

 

you have to mod the lines to use the type r brake booster it will firm the petal up you will also need a 40/40 proportion valve. the type r one wont work because its abs.
but if you have a civic si it might have a 40/40 proportion valve in it aready not sure you can check it and see.
also sounds like you need to bleed the brakes more. i had the same problem after doing my 5 lug trying to bleed the brakes by yourself dont work out too well
