2 disc brakes on one leaver

Bookmark and Share

I've seen a loads of brake leavers for sale that have a double nut in place that allow you to hook up two mechanical cable v-brake/disc brake to one leaver. One such example here for anyone not in the know: http://www.treefortbikes.com/images/raw/BR2904.jpg

I've yet to find a double hydraulic brake leaver though. Are they the same design as mechanical ones, or do the cables meet and join before they connect to the leaver? Anybody sell these off the shelf? 

Would regular MTB hydraulic calipers be up to this task or would the pistons inside need to be bigger for it to work?

twin hydraulic brake levers

I only know of one hydraulic brake lever designed to operate two calipers . It's made by grimeca. It's not cheap, unfortunately.

You might be able to rig up a standard MTB hydraulic brake with twin lines, either with a double banjo bolt or if you could machine up your own splitter. However, the volume of brake fluid displaced by the cylinder will probably not be enough to give enough movement on both calipers.

more brake parts

if you don't need the full kit, you can get levers etc. separately. They also do right and left hand calipers.
