kooka hydra levers with non magura brakes

manbeer · Apr 27, 2013

Hey...I was looking into possibly running a set of these with some older disc brakes and was curious to know if anyone has done it before. I want to make sure that the master cylinders move enough fluid to get the job done before I go switching things around. Any input would be appreciated. Thanks in advance

As Maguras (rim and disc) use mineral oil and most other companies use Dot fluid, then I'd be careful about using any disc brakes other than Magura as Dot oil will kill the seals.
Also remember that the Magura system is a closed one and most disc systems are open, to let heat dissipate - look at the Hope closed system and you'll see they had an adjuster on so you could move the pistons as the fluid heated up.
All that said, you could potentially mate the levers with older (say, 2000/2001) Magura disc calipers such as the Julies, as they used the same hoses and fittings as the HS11/33s.
I've got a bike with Magura drop bar levers fitted to Julie calipers, and it works - so far!
