TECH: Make a tiny brake fluid reservoir

[ran]

thanx for this...cannot believe its so easy...now that its explained...def going to do this...

[gmp]

thanks this is badass

[djturnz]

I am a bit lost on finding what Master Cylinder I need to match my KZ Caliper? I assume that any modern sportbike brake lever would have enough to power my old caliper, right? Perhaps my resevoir comes off like that already. I'll have to look.

[memper]

Its not about matching up a mc to the caliper by brand or what ever. Whats needed is the bore size of the mc. Take Brembo for instance. They have a 19mm(bore) x 20mm(pivot point) brake mc for dual calipers. That means a lot of volume of fluid is being pushed on your old OEM single caliper. Feel will be lost and the brake will essentially work like a switch. Dangerous but maybe you like to have your brakes really touchy, I dunno. If you took a smaller bore size and shorter pivot point then feel would be brought back into play but if the bore is too small then you get spongy brakes.
I have read that 19x18 for most sportbikes with 4 pistons, 19x20 for 6-piston calipers, and 16x18 for single caliper applications.

just set this up myself.
pretty easy and not alot of $$$

[edward]

did you use a bolt for the cap?

I have been following this post now and got to thinking about mc sizing for my rear brake set up. How does the resivor effect the operation of the brakes? Would a minimal set up work on my dual caliper rig I have been working on? Any input would be appreciated

does this badass mod work on stock harley master cylinder or only on the nissin set up?

[38knuckle]

i dig the sweet set up and the tech...always looking for new designs and american ingenuity. thats what this country was founded on...

[poop]

I just did mine the other day thank for the great idea I love it

[Mercado]

I just put on a hydro clutch on my ironhead chop, the specs state 11/16" bore.
I've looked everywhere and cant seem to find any nissin or the like, just the big chrome gross looking ones.
I would realy like to do this as it looks clean as hell, thanks guys.

[kylezero]

what size bars do those nissins work on.... seems like 7/8s is the only size im finding im running 1 inch bars..... what yall do ream the master cylinder mount out?

Yes. Find a 1" diameter grinding stone and have at it. Mine worked out perfect.

wonder how hard it would be to chuck up in the bridgeport

[Mercado]

Do you guys think a ducati 19mm bore would work if the slave calls for a 11/16 bore? i tried converting it but i have a disability called stupid.
Thanks

I opened up mine by hand. Just kept at it with a file, some rolled up 80 grit and a little patience. Took about 20 min.

[kylezero]

Awesome. Ordered mine last night with a matching clutch handle. Pretty excited

Fuck man . . that is some SERIOUS looking stopping power!

It's not as effective as it looks, the tire and traction is the limiting factor. A recent Horse issue did a story on a dual caliper build and it's use, an interesting read.

Do you know what issue i can find that in? I don't usually buy the horse.
