master cylinders

i have a 91 civic dx hatch and i wanna do a rear disc brake conversion but alot of write ups ive seen dont really the bigger master cylinders from there acura counter parts. i guess im asking with the master cylinder and brake booster from a 92 gs integra fit my dx hatch.

you can use the booster and mc from a 90-93 non abs teg. BTW, you can also just use the 88 or 89 accord m/c it bolts right up to the civic booster and really gives you a lot extra stopping power. Much easier than taking out the booster. The accord is a fifteen-sixteenths aswell but the bolt holes line up to the civics booster whereas the tegs do not

thanks alot. so i need a older gen accord. but now some thing else i jsut realized. what rear trailing arms from teg will fit under our fourths gens besides the da integra and the ef kit from password jdm.

also is the number on the side of the master cylinder the bore. because if thats the case then its already got a 15/16th bore on it.

It will answer any questions you have about brakes and suspension interchangability for acura/hondas. Sounds like you already have the right m/c. I thought the sedan was the only 4th gen with that m/c..maybe someone slapped it on there before you got it. I think you use 88-90 prelude, 4th gen ex sedans, and the 88-90 accord..they are all the same and when you think about it. Upgrading the booster just to get the fifteen-sixteenths booster on from the teg makes no sense when you can slap the same sized m/c from another honda on your stock booster. My pedal is nice and soft and many others have swapped just the m/c with great success. Probably the only thing you need up front is the 40/40 prop valve

well hmm my mechanic said it was stock maybe hes wrong who knows. but it definetly says 15/16th on it but its going bad and i gotta replace it any how.

does it matter if its a abs master cylinder or not. i found a mc and booster from a 91 si lude for pretty cheap but its not abs and that link i was sent said dont mix the mc and booster o nthat stuff.

Get a master cylinder for a 90-91 Civic 4Dr EX - it has the 15/16 master cylinder stock. I just picked up a remanufactured one from schucks for $55. They had to search around for the 15/16 one, but they found one. Same price as the smaller one. That's what I would do.

well its weird cause ive got a 91 dx hatch and it has the 15/16th on it. its a nissin unit. but my mechanic said it looks like its never been replaced. so? im kinda confused.

that is strange for sure. No doubt if you were to order an oem replacement you would see what I mean about the 13/16 being stock. Unless your brakes are too hard or something just stay away from the booster. Its up to you but I've heard with the bigger boosters you have to take the IM off to get them in there. Some have said they made abs parts work, most knowledgeable people say they will not work. I've never heard anyone putting a prelude m/c on though. Most use the m/c cause it bolts directly to the stock booster. Like the guy above said they are 55 bucks new so I wouldn't go wasting your time with junkyard stuff when a new one is so cheap

well i bout a new nissin unit which is the 15/16 bored unit i hate sure i paid for then 4g4d but im a brand monger these days. and besides i knew it worked before like really good. why not use the same thing.
