Just got some deore hydraulic discs on a second hand bike and the front and rear have different bite points (ie one much closer to the bars) however they don't feel spongy and there doesnt appear to be any way to alter this on the lever body itself. Does this sound like they just need topping up or a full bleed? Pads look like they need replacing too, but this shouldn't have an affect should it?
I don't know how old they are before anyone asks either which won't help too much and I don't have any photos at the moment.
Force the pistons back into the calipers and try again.
All my brakes have different bite points - including shimano deore
still work fine though
YMMV
Plum
Remove caliper from the frame
Squeeze the lever a bit to push the pistons/pads out a tad more
Top reservoir up with fluid
refit, the bite point should now be closer.
This is just trial and error, but dont queeze the levers too much so it makes the pistons pop out
