Before anyone says "bleed them" I did 4 times...really really well.
Ive already got a large 1" itr booster and mc set too.

-

I upgraded to integra front calipers today from my stock ex/si set. The pedal is really soft now and braking is crap-ola because of it.

Any suggestions other than "bleed them again"? Because thats obvious.

Im not leaking fluid. The bleeder screws are tight. Hose bolts are torqued accordingly.

did you bleed the brakes yourself or did you have help? there is a point to this question.

blaster834

Did you use new fluid or did you reuse the old when you changed this?

pdiggitydogg

always new fluid when bleeding

always use the same helper when I bleed - my mommy

pdiggitydogg

eh up for the hell of it

change the prop valve.

pdiggitydogg

besides the fact that all 96-00 share the same one
Ive done that already...and thats more of a rear disc thing

DC5ITR329

you might have a bad mbc. I've had lots of that happen when you bleed your brakes.

pdiggitydogg

highly doubtful
it was fine when I went to get the brake cleaner the day that I changed.
like I said I think its just a giant air bubble so a mallet and more bleeding is needed.

Does it require the bigger M/C for the swap?

pdiggitydogg

doesnt require it, no. I upgraded several months back (late winter).

(Also, I still have good stiff pedal while the car is off, so that rules out bad mc.)

make sure the calipers on the front are on the correct side. if they arent, the bleeder will be on the bottom. the air needs to come out the top. i have seen this before. you can swap them side to side. but if the bleeders are down, you cant get the air out.

DC5ITR329

do you know how to bleed corectly? because you would have to bleed the right rear then the left rear and the right front and then the left front.

pdiggitydogg

yeah theyre on the right side...R and L are stamped right on them, after all. Bleed screws are on top.

I bleed in the correct order, yes. This isnt the first time Ive done brakes. Here is exactly how I did it:
Rears then fronts. - check
Fronts again then rears. - check
Proper way according to helms (rr, fl, rl, fr) x2 - check

Thats all Ive done so far because I ran out of dot4 fluid - will try again on thursday when my special order of more ate blue comes in.

pdiggitydogg

ok ok...
After bleeding an entire liter of fluid today and giving it a test drive...unsatisfied. I thought
"I wonder if the pedal just feels soft because Im used to smaller calipers w/ the itr mc/bb?"

So is that a possibility? Would the brakes feel softer since these are just larger? I know theyre not that much bigger compared to ex/si. But...maybe?

Does anyone else have full integra brakes AFTER driving w/ stock calipers and using itr mc/bb?
I really dont think my pedal should sink so far.

(oh and those that say "its your mc" I reinstalled the ex calipers and they held just fine w/ very firm pedal. So its not that - My mc is fine)

pdiggitydogg

...up

ionno dude, personally, i have the si front brakes and the 1" mc and my **** is pretty damn stiff man. if you want it stiffer, you should unplug the vacuum line for the booster . Hmm on a serious note though, how much travel do you think you have on your pedal?

soundbomber

what is the difference between si and gsr calipers btw?

Dyn0speed

i heard u need non abs booster and mc for the swap!!!

Yes, it is a possibility. The Integra calipers have a larger piston and therefore they use more fluid. This is why cars that come stock with large calipers/pistons have larger master cylinders than cars with smaller calipers/pistons.

How bad is it? Is it undriveable, or are you just being nit-picky? As long as the car stops as quickly as it should and you can still heel-toe easily, I don't see any problem.

pdiggitydogg

You dont need a non-abs unit - You can just reflare if they dont fit. Not a big deal

Im really leaning toward this idea now...I mean it has to be it. Thats the only option left at this point. It doesnt seem to want to stop as quickly as it did w/ the smaller si brakes, but it may just be my imagination...that and the pads havent been fully seated yet either. I can drive it...but its just different and I dont feel as confident yet. I'll give it a few days and go from there.

(yeah the only difference between ex/si and integra (all are the same -itr) is piston size is bigger in integra )

soundbomber

ohhh, i get it then. yeah, i would miss having my firm pedal too

pdiggitydogg

No doubt. Im wondering if I changed to ss lines and put in an mc brace if that would make it more like it used to be.

TeknoJunki

this may not give you an answer but i had the same result (soft pedal) from some other upgrades.

my car is a 98 ex, with stock calipers and disc conversion in the rear. the rest of the system was stock. a few months back i decided to go with ss lines and the pedal got soft, but not through the entire travel. i also went through many many bottles of brake fluid trying to bleed them out, but in the end i left them the way they are. the first half of the pedal travel doesn't seem to do a thing, but the second half is pretty firm. there hasn't been any boiling of fluid and the pedal hasn't dropped so i just left it as is.

not sure if i'll ever figure out what is causing it. the only thoughts i had are that the lines are longer and/or their diameter is different.

good luck

pdiggitydogg i think you might jus be used to the ex/si calipers. i have an ITR 1" mc/bb with Si calipers and the pedal feel is short and firm and i would imagine switching out to a bigger bore caliper would definitely change the pedal feel. maybe rebuilding the calipers and some SS lines would help.
