Upgrading DX/CX front brakes

I have everything I need for the rear disc swap from a 94-01 teg and now im starting to do the front. I found this link:

►Ultimate OEM Brake Upgrade Thread◄ - EK9.org JDM EK9 Honda Civic Type R Forum

It helped me do the back but now for the front brakes it says i need ex knuckles or si knuckles, well here in Canada those car have the same size front brakes as my car...

Im pretty sure i will need to order SIR knuckles from honda but i was wondering if they were the same as the integra 94-01?

Any helps much appreciated..

Im confused though cause that link must be talking about the US ex and if its the same as the Canadian Si than how come the Canadian Si doesnt have the bigger front brakes?

Ive read about a 92-95 Si using the 10.3 inch front brakes but thats probably the US model..

I don't remember the size but I know eg Si has bigger brakes thann all other trims in that year range. Smallest rims you can fit on are 14s, the rest can use 13s.

Understanding the difference in badging.

The "US Ex" only came in 96-00 ej8 coupes.

Which make it the Si in Canada. Ant 92-95 "us ex" never existed. In that link they refer to the "si" em1 and "ex" ej8

tr1p you have a Canadian Si would you mind telling me what size front brakes you've got? Also do you have drums or discs in the back?

I get a 25% discount at Honda so i just wanna know what knuckle i need to order, i think the sir should work for sure i think.. then im going to find the rest of the rest of the brake components off an integra at the wreckers..

Yes, my Canadian Si is equipped with the same knuckles as the Canadian Sir. Which includes the same 10.3" rotors and same calipers. Note that my car is a 1999 Civic. And as far as I know any 99-00 civic "ej8 and em1" shared the same knuckles, brake booster, and master cylinder (15/16).

*The Canadian badge civic of 99-00 si and sir came in with ABS. The prop valves differed in size within the two classes. And another difference is the between the two is the front lower control arm. The sir came with a beefy one piece, while the si have a twopieced welded bends (kinda hard to describe in mechanical terms) .

As far as sizes of rotors, pads goes my ej8 is equipped with oem parts from a civic sir.

I'm not too sure about older years of the generation "canadian si" (96-98) about sizing, but I'm very confident they are 10.3" aswell.

The dinky little rotor brake setups are found in cx and dx of hatches and coupe (dx) only.

To sum it up you can use the sir or si front knuclkle and 94-01 teggies.*

I have a Canadian 2000 Si-G, which also came with the 10.3" front rotors. The non-ABS Si has slightly smaller rotors.

The "SI-G" was just a dealer option or gimmick to have point of sales. I believe it's a group package of an "SI" which the "G" had package of abs, ac, heated mirrors or whatever the dealer package option they added. The slightest difference your probably talking are the dinky rotors.

The SI-G "package" came straight from the factory. Nothinf in the package was a dealer ad on.

Are most 10.3 inch front brake system abs? Im taking mine front a teg, I imagine it wouldnt be easy installing abs and I dont really want to either..

I forgot to tell the junkyard i didnt want abs brakes for my real trailing arms... should be arriving soon but i havent paid, is it possible to remove abs?

^does your car currently have abs?

If not, just pull the sensors from the hub assembly and it'll be fine.

There definitely was a 92-95 civic coupe EX model in the US. A co-worker and good friend of mine had one. It was the same in every way to a CA Si coupe. But had power windows and was black on beige. Even those may have been possible here, I've seen white on beige Si coupes, not sure bout the windows, I'm a hatch guy so no windows or tweeter's from the factory for me. That car was later sold to Martin (DTP) who then traded it back for my old DA integ that he drove till he sold it and bought his current hatch.


OP-> don't worry if the donor parts you're putting on your car were from an ABS car. Won't matter. If your car had ABS then you would need ABS parts to keep it working. If the parts your installing are for an ABS car then they'll just have a spot to put the sensor and a sprocket on the axle that rotates with the axle for the sensors to read what is happening at that specific axle for ABS functions to work. The only thing that would matter in your case really is if your building it for show and don;t wanna have empty holes where the sensors would have been.

Martin, I know it's not super important but to add to your comment about the 13's on EG Si's There is one 13 that will fit. VX rims. They won't fit on EK Si's though.

Okay thats really good news. I really dont care what it looks like cause its just the bottom of the car you know..

Are there any differences other than the sensors between abs rear trailing arm and non abs? This is why:

I was reading a thread about brakes and I think it might of been MPR who posted they had good success with ATE slotted rotors from Canadian Tire. I picked up a set and realized the box specifically said for ABS equipped cars only but they didnt list any other non abs products... I decided to take my chances and get them anyway because I really cant see the abs system having anything to do with a rotor..

If i do happen to get a non abs trailing arm setup than will these rotors still work? I might call honda and check interchangeability with the two different rotors..

OK, so by what I can figure, the second brake disc size that was listed for my car at crappy tire is 9.4" to 9.5".

I'm not sure if that's dinky or not, but I think that's the size for the non-ABS Si's.

Even if that is the case, you might be able to use the non-ABS hub with an ABS caliper bracket to fit the larger rotor, but you should probably check that out with a pro.

ATE are quality. I didn't know about them till I worked at CT years ago but then having recently worked at a BMW/Volvo specialist I discovered a lot of the euro cars come factory with ATE brakes, including the callipers not just the rotors. I'm pretty sure that the ABS ones would have a clearance for the ring that is on the bearing part of the axle, not sure of the top of my head and, my EH3 is non-ABS so I can't picture it. Basically what you need to be sure of is the outer diameter of the rotors ABS vs non. If it's the same you should be fine.

I think this is what this referring to.
