Just this week alone I have seen about 9 (10 now!) of the same brake threads...so just to help everyone, post here about the swaps. Please do not post if you have not done the actual swaps, that's how all this missinformation spreads.

For starters, Honda is in the business to save money, and in this case using same parts between models saves. Therefor I'll say that ALL brake kits are interchangable from any civic or integra for '88 to '01 ( ed, ee, ef, eg, eh, em, da, db, dc and whatever chassis I missed) with the approriate pieces included.. no you can't throw gsr calipers on your civic knuckles and expect them to just bolt on, but you can however, utilize the whole knuckle/hub assembly and make out fine.

The rear disc brakes on Hondas have been the same forever (except DA piston caliper bore is about 1/16" bigger). When swapping out the rear brakes, I always use the original Lower control arms (LCA's) and toe links. If the model is the same, i.e. civic to civic, teg to teg, for the same generation, (some civc/teg swaps are ok) you can swap the rear lca's that have provisions for a rear swaybar. You will need the appropriate e-brake cables to the model of your car that had disc brakes originally.

The front brakes are where the upgrade really shines. Like mentioned earlier, calipers are not a bolt on affair (why would you want just them?) If you use the whole complete front knuckle assembly you will be fine. I again, use the upper A arms and LCA's from the original car.

When perfomring these swaps it's also a good idea to get the the donor brake master cylinder, proportioning valve, and if possible, the brake booster in order to use the brakes to their full potential.

Some people will dissagree with me on the swaps, but most have not done them or done them right. For example...

I am running 91 integra GS 4 wheel discs on my 91 CRX SI and absolutely love them. In this case some people will argue since the steering knuckle is taller for the integras...true, but unless your car is slammed 6 inches or somewhere like that, you will have no clearance (or caster) problems. So ef guys, dont worry all the swaps work for you too.

My 97 type R is currently rocking a 90 LS integra swap due to the fact that it was a theft recovery with no suspension. the brakes, being 7 years older, were a direct fit and provide me a way to move the car around. I posted earlier this week to a thread about EGs using DA brakes. Sure, go ahead..we put em on my friends 94 cx a few months back.

The most important and safe factor about these swaps (and one the nay-sayers never do) would be a proper 4 wheel alignment when done. To do this you should get all the neccesarry camber adjustment kits in order for your car to achieve optimal handling. Another thing to consider before slapping all you rhard earned cash down is, wheels. With the larger brakes form an integra GSR now on your civic dx, those litlle 14" CRX wheels won't cut it. Be aware of wheel offsets and backspacing as well as spoke design before you purchase.

Well enough rambling, please post your experiences as well as other insights that I am sure I have missed.

*Cliff Notes*-----just a what can/can't be done to swap brakes between models. Trying to cut back on the missinformation.

 

arite ill start it! i have a crx hf. when i got the ride it was completely stock. so i did the motor tranny swap but thats not the point here. i wanted to upgrade the brakes. i got 90 teg knuckles calipers hubs n rotorscuz im using the zc motor n tranny($150. the stock brake lines worked just fine. i used the factory upper n lower control arms,sway bar, i used a crx si master cylinder($50) as well as proportioning valve($40) cuz i converted to rear discs also but ill get to that in a bit
it was a really easy swap to do. only thing is the knuckles f*ck up caster so it made the car squirrely and have bad steering hesitation. i went to firestone n had my toe corrected and my caster corrected($160). car rides like a dream now.so dont listen when they say this swap makes ur steering angles incorrectable.
for the rear disc conversion i used the crx si trailing arm calipers rotors hubs($150). i also kept the factory upper n lower control arms and toe links. i got lucky when i ordered my stuff from password jdm it came with the crx si e-brake cables. this swap was easy as hell also.
the total cost for replacing all 4 rotors and pads was in the ballpark of $100. this swap is easily done in hours. my final cost was about $500 but that includes my shipping costs from the places i ordered parts from.
id recommend going through passwordjdm, jdmshit or hmotors. these guys were great to deal with after dealin with some of the other places out there. after i called my orders in i got calls from 2 of the 3 places to make sure they were sending me the correct stuff. and the only one that didnt call was hmotors and when their delivery came it was everything just as i had ordered it. also i got things for cheaper than they were listed on the website so make the calls n reasearch everything before u jump into it.

if u got questiong pm me-sabertooth or hit me up on aim-mikeybreu. ill be lad to help. good luck to those who need the info

sorry i forgot to mention i ued my stock brake booster

Good post, I hope we can dispell unneccesarry myths about brake swaps and let people start swaping away. I too only run the MC and Prop V. I left my SI booster alone. Oh and just to add to the ED guys, the 91 civic 4dr EX has the same size front brakes as the DA integra but shares the original length knuckle that our cars came with in case your too much of a worry wart.

 

I needed this. Thanks!

 

My car 91 std.

I have upgraded to GSR brakes system. Everything is the same the booster the valve everything is std civic. The brakes are nice very power full for a little civic with a swap.

here is my question my tires have wear in the inside like crazy what is wrong..?
someone told me something about tow and my tire squeeks when go upramp or sharp right turn..

anyone explain that

 

Toe is the angle of which your wheels either point inward or outward . Most common causes of tire wear like yours is negative camber. When you put the suspension on did you have the car aligned? If not take it to an alignment shop and they will do the best they can depending on how adjustable your suspension is. Either cause, it can be easily cured if you have the correct parts.

Actually, the rotors and calipers on the 1991 EX are the same pieces as the 1990-1993 Integra! Just keep in mind that these pieces are NOT compatible with anything but 1990-1993 Integra or 1991 EX hub/knuckle assemblies. But yes, 1991 EX knuckles are the best option for bigger brakes on ED Civics/CRXs. If you can find them, that is. They are quite rare (although I just bought a set today at Pick-And-Pull!).

Wich will get you into big trouble if you try to swap SiR knuckles and LCA's onto your CRX.
The mounting pattern and positioning of the radius rods is somewhat off.
The angle from the crossmember to the LCA is different.
The front crossmember is different on the SIR. And so are the radius rods. I have tried, and failed to make it fit with OEM parts and machining is not an option because there's not enough room to shimmy some off.
So you should keep your original crx LCA's in this case.
Also, don't forget to use the steering rods too... they're a good inch longer on the SiR because of the different knuckle. THis WILL give you alignment issues.
