I recently installed new brakes (Shimano SLX 675), shortened hoses for front/rear brake, done bleeding but even after that rear brake lever feels much softer than front. (I had identical issue with old brakes (M446) which acted in the same way and that is partially the reason for asking this question).
New brakes work fine, they have nice stopping power, there are no signs of oil leaking etc... It is just that rear brake lever feels much softer (and I don't think it is due to lever reach adjustment; it isn't nearly reaching handlebar).
Can the longer length of disc brake hose (rear breake) influence the 'feel' while braking (assuming brakes are correctly installed and working properly) or there is something else causing this 'problem'?
