Mathauser hydraulic breaks

Has anyone heard of Mathauser hydraulic breaks? They look sillilar to Maguras.

If you have heard of them what do you think the chances are that I would be able to find some extra break shoes for them? and do you think they would fit in the magie 4 bolt mounts?

Thanks

ERIC

I didn’t know they made brakes, I just thought they made maggie pads. Learn somethin’ old every day I guess.
