I always love Friday evening, time to relax my mind by finding more things to modified
So let's talk about rear master cylinder again:
The Brembo RACING Rear Billet Brake Master Cylinder With Reservoir Product code: XA2.C6.10 came standard with build in push rod. While the original stock rear MC has the removeable push rod.
That means, I need to replace the Ducati by Rizoma rear set push rod assy. with just a female rod end. Doing this modification also means I need to find a NEW helper springs.
There are several helper springs kit for rear master cylinder available, however none is as nice looking as this Japanese kit form G'craft. And because like some "undecided voter" out there, I was also having the same dilemma,
but only for "undecided color"
Because of that, I decided to just buy several kits with different based ring color and decided later. I also purchase the female rod end, picture below.
If you pay really close attention, the Gold and Red kit is the non adjustable model (spring tension), while the silver color is the full adjustable (spring tension) model.

After waiting for several weeks, my order arrived and I immediately want test fit them so I can choose the best color, however, I found one problem.
The Brembo push rod was M6 thread, while the Silver Anodized Gear Like adjuster hole is M8... ups...
so... I have to buy M8 to M6 thread adapter with the correct pitch, and I can't find it due to the pitch size... but... since I am not giving up even after few days of searching...
it finally pay off and I find the one and only seller who sell the M6 to M8 adapter with the right pitch and below is the picture of the thread adapter and when I install it:

Ok, so now I am ready to test fit and see which color is the best (for my eye)

And finally, I decided RED it is
, so I proceed to test fit on the Ducati by Rizoma rearset:

Well, another problem arises... turn out that same adjuster anodized silver gear like plate hit the bracket of the carbon foot guard...
which means, I can't use the fully adjustable (spring tension) and have to use the cone shape spring. this after all the time I waste just to find the right thread adapter and then wait for it to arrive... but that's ok...
Now, remember the rod end that I bought from Japan together with the G'Craft helper springs kit, well, the cast is rough and I don't like it... so I purchase another rod end kit here in the good ol' USA
In the picture below, you can see the top rod end is the one from Japan and the bottom on is the one from USA. The USA sourced is much nicer, right? so USA it is

Ok, before I show you the assembled helper spring and rod end, I want to show you some other modification...
This time is for the nipple that will connect this Brembo Racing Billet rear master cylinder to the Ducati by Rizoma reservoir.
Initially, I thought (from the picture of the Brembo Racing Billet rear master before I buy it), the hole for the upper gold bolt is the regular banjo bolt thread, so I buy a nipple from Vibrant Racing and Anodized it in gold:

But I was wrong, the hole is much smaller, so again I look all around the world to replace that gold bolt plug with the right nipple and finally (took several days to look), I found one source in AUSTRALIA. They have 3 different nipples so I just buy all 3 of them since the shipping cost is high if I made mistake and need to order another one. And of course took couple of weeks to arrive and it finally arrived:

After test fitting them I found the ideal length and diameter and install it onto the Brembo Racing Billet Rear MC. However it was made from Stainless Steel so I can anodized it gold. (Also notice the helper spring kit and end rod was still the wrong one):

Oh, I forgot, I also use this o-ring to make a good seal:

And finally below is the correct configuration including the correct helper spring and end rod, plus notice the Stahlbus quick bleeder valve with the matching anodized red cap

fiewww
so many modification just for a Brembo rear billet master cylinder...seriously, I am already tired just posting this post now ... but wait there are more !!!
I still need to replace some locking nut and also 2 bolts for the cover of the integrated reservoir with ProTi Titanium Bolt (will order soon),
and I am also wait for the correct diameter hose to connect between this Brembo rear billet master cylinder to the Ducati by Rizoma reservoir (which have different nipple and thus hose diameter),
and I also need to drill the 2 mounting holes for the Brembo Rear Billet Master Cylinder from threaded (as come from Brembo) to through hole, because the threaded part will be on the Ducati by Rizoma rear set.
But I am just waiting for the hose and already bought several different shape and diameter of nipple diameter adapter:
