I would've gone for something circular... f**k sketches. I had a better idea... basically... you know how a disc brake works? It turns rotational movement into linear movement. So... if you use the same idea, but make what would've been a pad be part of a piston, it would squeeze fluid out. That was the principle of the original idea, but then I thought, why stop there... why not have that integrated into one slave piston, squeezing the fluid top push out one pad, whilst also moving to a crossover and operating another piston. This second piston could be a standard magura piston However... What if you used a straddle cable and had two of the first pistons? What if... you had no fluid, simply what would effectively be a straddle cable, and two separate sides of a disc brake caliper? They could be sized to fit magura mounts and built to take magura pads... just be cable operated. You heard it here first! If anyone makes this, it's my idea.. I want royalties
