Is the piston area of your new brake calipers increased from stock? If
that is the case then you will have to move the master cylinder further
to move the pistons the same distance. This pedal travel will be
relatively easy until the pads come into contact with the rotor, and then
you will have the hard pedal that you expected in the first place.
Just a thought.
