TECH: Make a tiny brake fluid reservoir

[Cycleboy]

Any of the modern sportbike radial style will work......and..................................... .they usually come with an electric brake switch that is easy to wire to the lamp!! I use one off a zx14 (only because it was the cheapest one on ebay) and the stopping force is crazy! set up is a sportster single front caliper on a XS650.

i'm confused about this!.... are you just using the stock master cylinder or do you have to buy a replacment? not sure if it was covered and i missed it but if some one could clearify that would be awesome thanks guys cause i really want to take care of some of the bulk on my bars

I got mine off a sport bike. It's a Nisin, off a GSXR, I think.

You pull the stock master cylinder and replace it with a piece of plastic tubing. Instructions are earlier in the thread.

I get it! like i said i wasnt sure if i missed it or not i read the whole tread from beginning to end to try and make sence of it. but i wish it was that easy just pulling it off! lol antone know what will work for a 90 lowrider? or where to find it ?

All this tech is about is changing the reservoir. If you already have a hydraulic front brake, and are happy with your current brake handle/control, all you are gonna mess with is the reservoir, nothing else.

No no no no... That would be a way bad idea, lol...

Just the reservoir.

i like this gonna give it a try

Nicely done, but I think a harder plastic would look a little better as oppossed to seeing it vibrate in front of you, blasting done the road.

ok so if I wanted to really change out my front brake system then i would need the matching disc brake for the caliper....then the matching master cylinder? because a lot of the sport bikes have dual front brakes i am seeing a lot of "sets" on ebay with those dual brakes.....how are you guys putting together these set ups? i love the idea of having that small master cylinder...

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

[gmp]

thanks this is badass

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.

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 $$$
