I thought the SiR was the same as the US '99-'00 SI's, which come with the same 7/8" master cylinder as the US EX's.

If the Canadian SiR's really come with 15/16" master cylinders, will it bolt into 99-00 Civics without ABS? Specifically, bolt onto the brake booster and all brake lines bolt on without rebending?

 

Because the sir had abs, the si didnt

So...youre going to have that larger fitting issue.
Its not a big deal to cut the end off, replace with an abs size fitting, and re-double flare the line - autozone even rents flare sets

 

oh yeah! the SiR's come with ABS.

Thanks...I'm just gonna get something that's bolt on haha.

 

alright...i did a bit of searching, and some people have used the sir mc successfully?? can anyone shine some light on this?

Here is the Sir MC

 

theres no way around it man
if it uses abs fittings, you have to replace and re-double flare
no way around it
