Dual circut master cylinder help needed.

**Bretto** · 05-07-2006, 10:14 AM

Well i'm so close to finally getting my ke20 registered. only a few things remain,
Anyway this is one thing that i wouldn't of thought really mattered but seems it does.
Here's the problem.
I'm running ma41 front struts/brake setup. And also big rear discs which i'm not too sure what they are off.
Anyway, the engineer wants me to put in a dual circut master cylinder and i know its not going to fit cause the ma41 master sticks out way too much. Its going to hit the throttle body. So i need to get one which sticks out same length as a ke20 one and either has a right bend in it, or is stubby and can fit in the gap.
I'm pretty noob on this stuff, was thinking of taking it to a brake place and getting new brakes fitted but thats way too expensive.

Any ideas?
Anyone gone through the same sort of problem?

Are you fitting the new master cylinder in the same position as the factory located one?

Are you running a booster or not?

I do have a booster and yes i had wanted to put it in its original position. Eventually in the next few weeks the s/c will be gone, but no too sure how it will fit with a inlet manifold in the way?
Maybe i just have to put it in another position.

hhhmmm mounting a booster and master cylinder in the factory spot is a big ask especially with a 4AGTE, not much room once the manifold is on. I fitted a TA22 booster and a 15/16" master cylinder as far to the right as possible (the master cylinder is a few mm from the strut tower). My hydraulic clutch master cylinder now resides where the factory brake master cylinder was.

My setup required some refabrication of the pedal box.

Yeah i think i might just take it to a brake place and get them to give me a bit of insight.
Do you know of any dual master cylinders which are shorter than say a ma4 series?

What is the length of that master cylinder? I am not familiar with them.

I'm not too sure what size they are.
As i'm not to sure what size the ke20 one is. I called pittwater brake and clutch and he told me that a few ke20s he know of have got ke30 or ke55 dual master cylinders. So i was thinking maybe i could put one of them in. Only problem is that its going to hit the throttle off the supercharger and i'm crap with customizing brake lines. How hard is it to move it to either near the strut tower or somewhere else?
