i just had tihs put on today. im using the stock vaccum booster, with SS lines and carbotech panther+ pads front. ive noticed that the pedal only moves about halfway as far down as the stock one did. i could psh the stock one to the floor, and this one only goes about halfway there. granted its locking the wheels up at that point, but im kinda worried once i get it on a track the brakes are gonna fade and i wont be able to get any extra travel out of it. has anyone else had tihs problem? and how would i go about fixing it?

 

your not supposed to be able to put the petal to the ground.

With the bigger m/c your able to put more pressure on the brakes then before.
Its a good thing.

All brakes fade if u ride them hard enough, but now you have more room for better braking, quicker breaking, faster braking etc.
fading is just a byproduct of heat. Heat is generated from your brakes working!

 

Is the EX MC a bolt on? I've always ready that LS booster/MC's are a good bolt on affair, also.

i mean its physically not ever happening. the pdeal hits a stop or something that prevents it from going farther down. if it could go down farth3er, i would have an easier time stopping from 80mph as the pedal hits a stop then i cant slow down any faster.

 

any replayds?

 

I slapped a 90-91 Teg MC and brake booster on my ride and it brakes great!! All I need is to do my big brake conversion and I'm set....

 

I'M using a Integra LS 93 ABS master & booster (1" cylinder) on my 4th gen, the braking power is now really great, and all my brake stuff are still stock at this time

 

If all you did was replace the MC and didnt mess with the pedal them I'm sure it will go down further, its just the simple fact that with the upgraded MC its putting all the pressure it can on it, thus not allowing you to push the pedal in any further. You say it locks up the brakes at half travel so how coudl it go any further?

 

if i do a 90-0 stop it will not lock them up. i will slam the pedal and the pedal hits a stoping point about halfway to the floor that prevents me from locking them up.

if they are hot, it wont do it. 60-0 will lock them up. i beileve that if i had the extra travel, that i could lock them up at 90.. do you see what im saying?

 

Are the 90-91 Integra MCs a direct bolt on? Cuz there are some at the yard, I should get one. How big are they. Do the bolt on as in no bending of any lines and all that crap?

 

&lt;- tried to stay with a civic MC for compatabiltiy reasons. looked like my choice was ill-fated as now im in a barrage of problems

 

Wait what MC did you end up using? EX? Cuz I heard EX one is the best to use.

 

i did use the ex
but for compatability reasins i must insist on getting used parts that are already adjusted to the chassisim having nothig but probs on this car..

 

Open a bleed screw and make sure the pedal is not be physically prevented from travelling to the floor do to an install problem. If it goes to the floor with no fluid pressure buildup then you are ok. The fact that you can't lock them up from 90 is that your leg isn't strong enough. The bigger master will flow more fluid thus having less travel, but will also reduce the force multiplication.

 

A bigger master cylinder gives less pressure in the line for the same pedal pressure. It moves more fluid per stroke that is why it doesnt move as far.

LOOK UP AT MY POST!

 

you can use a 94 del sol non abs master cylinder...bolts to stock booster..its 7/8 and works great with integra discs front and rear

 

Dude, I don't think they get what your trying to say.... It's like the piston IN the master cylinder he installed is hitting something down inside the unit itself... Like literally hitting a wall. THe petal STOPS because it CANNOT PHYSICALLY move anymore, it's metal to metal, not fluid pressure buildup.

He is wanting to know if anyone else has experienced this problem after this swap.

Jeez. Learn to read and answer the question, folks.

I'm simply saying its pressure buildup because thats how it is in my EX, I think most of us would have to drive his car and hit the brakes to really tell. With the info given the common and most likely reason is buildup. Its like saying "I have this noise, what is it?" hard to tell without being there.

 

check your brake line fluid.. come oon guys this sounds like air in the hoses : \

sorry didnt read all the post..
shu said release and press all teh way down.. &lt;== i would do that, then you will know if it's the lines or the mc.. was the mc working b4 you got it?

 

I swapped in a 91 EX Mast.Cyl and Prop. valve.....and been nothing but happy with it....no more mushy pedal on hot days, brakes lock awesome.
