Is there a lot of movement in the lever before it starts doing anything, or just a small amount with resistance by little braking?
There is very little pedal movement.
I suspect the fluid is quite old - the front brake looked like folgers before I changed it.
I've felt old and improperly bled brakes before and this isn't it.
I'll take the caliper off and make sure that motion in = motion out and that the piston slides nicely as as start.
