Ok so i just bought a rear disc conversion (or part of it at least) i just need a master cylinder e brake cable and brake lines... Now ive done some research and found that since the rear discs are from a GSR i need GSR brake line which is fine but.. Can i use an Si master cylinder/proportioning valve and an Si e brake cable with the GSR brakes? Any info would help thanks.

 

It would definetly help if we knew what kind of car it is.

leave the MC alone!

 

97 civic hatch

 

Leave the prop valve and MC alone.
99-00 SI e brake, and brake lines. Integra brake lines would work too.

 

awesome thank you!!! that will save me time trying to find that stuff... now ive also heard that EX e brake cables work too is that right?

 

No, drum cables are diferent. It needs to be from a disk car.

 

i thought EX was 4 wheel disc since its the model below the Si

 

Not that I know of. I was under the asumption that only the 99-00 SI got rear disk. For 96-00 anyways.

 

Wut... no.

I've had two EX's, neither with disc brakes. Maybe I got jipped.

 

Let me know how it turns out will you? I'm gonna do the same thing in a couple weeks. Can't wait.

 

What do you wanna know? Hundreds of people have done the conversion. It's spendy. It doesn't improve braking THAT much. It's more expensive to work on and you have to maintain it more than drum brakes. It just looks good.




EDIT: Reasoning for a rear disc conversion not doing much is that only ~15% of your braking power is in the rear. If you want a real notice in braking power, do a front disc conversion, where ~85% of your braking power is. Or maybe consider a bigger rotor conversion. Like some S2K rotors.

 

Word will do just gotta pick up the last parts

 

Im probably wrong i just based it off what i heard btw did u go to capital high school? Cause i might know u haha

 

Nope. Graduated at Tumwater

 

your oem master and proportioning valve will be fine. e-brake cables from an si. rear brake lines can be from an integra or civic si, doesn't matter since they're the same.
