New set up

[Slide~or~die]

So, im designing my hydro set up(nothing new or special) but am coming across some question i cnt find the answer to.


So u know what my plans r, i plan on doing a "standalone" hydro ebrake set up(not inline with the braking system).


set up consist of::::

front 300zx calipers mounted in the rear via custom bracket
Either pbm ebrake w/ reservoir added from willwood
or new MC with res attached and different bore size.
obviously lines nd other things to make it work.



I have questions??????????????????


(1)Would i need to use i bigger bore size because of not running an inline style hydro e brake?

(2) Does bigger bore size make pull effort easier or harder??? EXAMPLE (5/8 more pull effort than 1 1/16)

(3)There is about a half inch gap between the brake pad w/ the pads fully suppressed and rotor pushed to one side as shown in pic below, now is that a problem? or will that work?

(4) What bore size would u recommend i use? cuz at the moment i have no idea what would be best nd dont want to waist money trying to get the right MC.

this isnt on the car yet, trying to get a game plan first.
Thanx in advanced for any help given!

The bigger the bore, the more effort you need to push out the piston. so a 17/16 requires more effort to push out hte piston than say a 5/8, but a 5/8 will feel mushy this is obviously with the same booster.

With the break pistons fully supressed, 1/2" seems like a lot, but in your picture it looks like its less than 1/2". Just check for leaks and make sure a piston doesn't pop out hahaha, other than that... it looks ok....

I would go with a 15/16 first, that I think is a very good first try....

thanks for the info!!!

and yea its for a ebrake set up, so there will be no booster, and as for the bore sizing i figured thats how it worked but wasnt sure...



im gunna go with the combination remote cylinder, bore sizing is down to 3/4th(.75) 7/8th(.875) and 13/16th (.8125) so there all within each other.

ohhh and full stroke of each is somewhere either at 1"-1.4"


i think anything bigger is gunna be over kill, and i dnt want the mushy feel of the 5/8....but sense iv decided to do this with the PBM hydro e brake, im gunna get the MC with the remote res. and attack the remote res to the PBM MC(5/8th) so if the 5/8 is not right ill have the other MC of my choice.



having no hands on experience except for using my reg brakes:duh: im gunna just go with the middle bore size (13/16th) nd i guess trial nd error.


i will post pic of set up, somewhere on here=p to show, nd ill prob be able to answer anyone elses questions about this by the time im finished!


any info found to be stupid above^^
plz tell me!
thnks!

I think try with a 5/8's first, because obviously, your hand isn't braced while pulling so if you go pull type hand brake, 5/8's is the way to go unless you are like have big right hand. If you go push type like D1 setups then something a little stiffer is the way to go...

Push type you get more leverage hence you can afford to go with a bore closer 1" but if you have pull type like normal ebrake, 5/8" I would try it first.

[Slide~or~die]

ahh kk, well im not sure yet if i wanna make a custom handle and replace my stock ebrake(relocate stock cable brake) or mount it next to it like a 2nd shifter lol

buttt

im gunna try the 5/8th first, cuz im going with the Powered by Max ebrake with a res/ added, nd see how it feels, mounted so that i would pull the handle towards me.


when u say push pull, wouldnt both types be considered pull?(i guess with the PBM ebrake it depends on how u mount it).

[slider2828]

Yeah depends how you mount basically

[g6civcx]

your hand isn't braced while pulling so if you go pull type hand brake
Push type you get more leverage

Are we sure about this?

[Slide~or~die]

what he means, is..... well lol

in essence hes saying that pulling the ebrake up(like stock cable brake) takes more effort than to push/pull the handle towards u like a Powered By Max ebrake,(mounted backwards or w.e) =p


IE: k sport set up and PBM set up.


Now that i take a look at the ksport ebrake, i might start with that one, sense i can mount it either as pull(stock style) or push type(d1 or pbm style) because i wont have to modify the PBM handle to convert it to pull(stock style) to see how that feels... cuz im doing both styles nd comparisons.

[slider2828]

Well yeah, looking at the use perspective.... not from the mechanical perspective.

But slider or die got the idea....

[Slide~or~die]

so which style would u use a bigger bore size for?

d1 or stock style?

[slider2828]

Probably D1 style I would use bigger bore.....

[Slide~or~die]

alright

i also just got a new job, so this should move along alot faster!
