My small winter side project. Rear brake res. eliminator kit suitable for most rear brake setups. Kit includes:

1.) Polished Billet cap - VENTED. - quality steel ball and spring
2.)30 cm (cca. 12 in.) Tygon 2375 chemical resistant tube (newer version of old 2075 tubing).
Tubing Inside Diameter: 5/16in (7.94mm)
Tubing Outside Diameter: 7/16in (11.11mm)
Minimum Bend Radius: 1-1/4in (31.75mm)
will not sveat, resistable to chemicals (e.g. brake fluid) and weather influences
3.) spring hose clamp for the top and worm drive hose clamp for bottom + zip tye for securing the tube

Will ship worldwide; 35$ shipped for all you figher maniacs :) Orders on:[email protected]

Sorry no pics of it fitted - yet. Will try to get some as soon as possible. I have sold cca. 10 kits localy but have to find one in action to take pics :)

Inside the cap is steel ball and compressed spring. it works similar to release valve. Keeps the water out and compensates for brake pad wear/brake fluid movement. It should work even without vent, but I think that vented cap ensures smoother operation of the brake system or is at least safer. - no vacuum buildup in the tube - it plays the function of rubber membrane in the brake fluid reservoair

Yeah you don´t need rear brake reservoir . The type of brake lione (pressure line) doesn´t matter - could be standard/rubber or stainless. But you should still change your brake flouids every once in awhile (I do it on 2-3 years).
As for the price-I can go a bit lower..lets say 30$ shipped - WorldWide.

Nice kit but I am just not sure about the vented valve idea..... surely this is letting new moisture loaded air in to the brake fluid where an OEM brake res has a rubber diaphram that moves with the pressure on the brake fluid side but does not let new moisture loaded air to the brake fluid. Brake fluid degrades with moisture from air and this why they OEM res is sealed with a diaphram.

What if you replaced the ball with a piston type seal (think engine cylinder piston and sealing rings, but using oring's) that was spring loaded like the ball? This would keep the air seal to the fluid but would allow for the pressure differences.

Just a side note, the honda HRC rear brake res kit dosnt have a vent at all, it just uses the clear tubing and a plastic cap. I think it relys on the natural flex in the side wall of the tubing to compress when the pressure increases.

I just bought the new tubing from kurvy girl but I don't see the reasoning for the Honda breather plug.
The breather is for the air intake, who decided that it would keep moisture out of the brake fluid.
as the fluid cools, it'sjust going to sucky atmosphere into it, moisture and all.
the tube, zip ties/clamps, and a good bolt is all you need.
I recommend a bolt that came with a washer. Cut the washer off and you have a non threaded
location to zip tie the tubing.

I dont believe the bung from honda is a breather. Its just a bung http://www.davidsilverspares.co.uk/parts/by-part-number/part_17370419700/
The honda set up is a sealed system that you have to have an air gap for expansion and contraction of the fluid. I dont think a race team would use a set up that has the chance of droping / leaking brake fluid on the race track or rear tyre from a breather/vent bung.
