    .....and '87 Accord LXI...i have two of these in great shape. pm me if ya want one:)
  • thanks for the info i just went to the local parts store and there computer said wagon only and it was like 290 bucks i as like screw that. why use an older cars master i am wondering fakejdmf8. is it bigger.
  • FakeJDMEF8FakeJDMEF8 Senior Wagonist
    the ex and the lxi share the same 15/15" MC.....the only bigger one is the 97 type r without ABS(1")...and the del sol (not sure on years)...but with both you have to install a new brake line fitting. which is a pain...

    It's working great! I was just super paranoid at first. Brakes are one of those things that just can't fail lol
  • thanks for the heads up

    2nd gen integra abs master is 1" also. I was able to get an adapter at a local hydraulics store for under $5 so that I didn't have to redo any fittings. They didn't have the fitting in stock but it was in the book.

    I got the master and booster of a friends wrecked car for free. Used the master for a core and paid something like $32 for the rebuilt one with a new reservoir. As far as squeezing the huge booster in.... Your gonna have to pull the intake manifold. Even then it's a real bitch to get it in there. tried to get a pic of the little adapter.

    The swap is a pain, worth it though. She stops quick!!!!

    quick note too. My booster is mounted upside down so that the vacuum line is tucked outta site.
    oh yeah. just figured out a week or so ago that I have to drop my intake manifold back to replace an alternator. Just a small drawback of stuffing a big master cylinder in there.
  • Just picked up a stock replacement - 1991 6speed AWD wagon - new (not rebuilt) master cylinder from Autozone = $26.00 with new reservoir and core return.

    FYI the flange is the wrong patter for the stock booster......

    88-91 prelude is good also...15/16... i got mines for $20 and stops great..

    No need to upgrade the master unless you have larger calipers. With a larger master comes more pedal pressure to get the same stopping effect, though with a shorter pedal stroke. If you have stock size calipers, stick with the stock size master.

    On my car I have 90/91 Civic EX brakes, and the corresponding master, works great.

    This is so true. I used my stock MC on my 96 civic CX with ITR 5-lug brakes. Brakes didn't engage till super low to the floor.

    There is also such a thing as running to large of a MC. Putting a 1'' MC on a stock car is gonna suck!

    it's like your saying since ur car came with a stock engine, dont swap for something bigger and faster... " if you have a stock engine, stick with the stock HP " LOL...

    Wrong analogy.You can use a larger MC just don't go too big.

    That's not what I'm saying at all. Brakes are a system, and designed to work together. Everything from the motion ratio on the brake pedal itself, to the bore of the M/C to the fluid capacity of the calipers and wheel cylinders. Increasing the size of the m/c is not like putting on a cold air intake. There is NOTHING to be gained performance wise by increasing the size of the M/C with no other changes. What will happen is that more pedal pressure will be required for the same level of brake pad pressure, and there will be less pedal stroke needed.

    If you increase the volume of your calipers, then you will need a m/c that flows properly for your new, higher, flow demands of your calipers.

    As you like engine analogies, here is one. If you have a 1.6l engine, you aren't going to go and put a tractor trailer turbo on it, or a 5" exhaust, as they are not appropriately sized for the flow of your engine, and by doing so, not only will you not get any benefit, you will likely have adverse results.

    I'm all for increasing performance and capacity, but modifications need to be done to complement other mods, not just to say "it's bigger".

    which model car and year is this setup from?
  • i have a 15/16 ex master cylinder. it was a little cheaper than the wagon one at my job. i have a booster from a crx si, which is smaller in diameter than the wagon booster.

    can you guys describe what it feels like from stock m/c and booster to bigger, with keeping the same brake caliper.
