Do you need to put an Si Master Cylinder, Prop Valve, and Brake Booster on when you are swapping an EK's drums for Disk?

Thanks in advance.

You only need the master cylinder. If you have an EX you need the proportioning valve too, if you have DX, CX, HX, or LX it's already the same prop valve as an SI.

bah...damn EX...Im throwin some GSR disks in the back of mine so I feel ya.

Dont gotta redo any of the plumbing? just change out the prop valve?

and btw, wont an Integra master cylinder work too?

I don't think you need a master cylinder and brake booster..

GetawayInMoscow

I think so, but almost all Integras came with ABS, where as no SI's did.

I don't think you are correct in your proportioning valves;

SiR/SI/EX model 46210-S04-852

Other models 46210-S04-902/901

The EX has a different proportioning valve because it has bigger front brakes than the other models, but still has drums in the rear.

* = Uses multiple part numbers.

You are talking Canadian part numbers there.

Groovinator

not a difference canadian or not, the fact is they are different valves.

I was just trying to clarify things, I've always put in Si/Sir valves for all the swaps we've done as that's the only civic with rear discs up here.

EL Vap133

Well here in the US the USDM Si uses the same prop valve as the DX, LX, CX, etc. The USDM Si brake booster is also the same as the DX for sure.

NightCat

Someone told me that you can use the EX valve or some part of the EX for dear disks

EL Vap133

How so, the EX did not come with rear disc brakes?

NightCat

I dunno...I was talkin to some guy at a local junk yard and he had disks on an EJ1 and said somethin about "well if you have an EX.."I dunno wtf the dude said..just wonderin if anyone knows. there's somethin about the EX that makes it better to disk swap in.
