Can i use the 07 xtr dual control hydraulic brake levers for other hydraulic brake systems like magura?
I very seriously doubt it will work. Plus, disk brake systems are so expensive, I'd never want to take the risk of messing them up by attempting to mix and match. As you probably know, hydraulic systems are usually sold in complete assembled sets - you get the levers, brakes lines, brakes and rotors in one complete package. They are not usually pieced together. So, as soon as you take one system apart, you will have to completely bleed the hybrid system to make it work. Secondly, Shimano recommends only Shimano mineral oil for their brakes, while Magura recommends only Magura brand mineral oil. They both warn that using the wrong viscosity oil will cause problems. I am pretty sure Avid uses standard brake fluid which is incompatible with mineral oil. Finally, I am willing to bet the systems have incompatible design parameters. Thus, even if you figure out the oil issue, get them bled, etc. one set of levers may not properly actuate another set of brake calipers. Hope this helps.
