I got the BR-M445L + BL-M505L a month ago. I am new to hydraulic disc brakes, so I can't tell if there is any problem with air in the system or other problems. Asked a mechanic and he said the brake is fine, though.
I am unsure how to describe the problem. The lever feels awkward. The pivot point of the lever is too far forward (compared to Avid Elixir and other levers with the oil cylinder along the hose direction). I feel as if the lever is just too far from my fingers to comfortably squeeze. And I can't reduce the reach from the adjustment screw, because it then hits against my glove.
The problem is bad enough when using 2 fingers, but is terrible when using only one finger - the lever hits my middle finder and the travel is insufficient to actuate the brake.
Is there something fundamentally wrong with this lever design, at least for some cyclists. Or some trick that is a must-do (I installed the already bled system myself)?
