Hi! I was trying to adjust my hydraulic brakes. The front disc is a bit warped, but the calipers are extremely tight [first picture], so the disc rubs on the pads and it basically need to be perfectly true not to rub. An upside to this is that my front brake is extremely sharp on the bite.
Conversely, my rear brake [second picture] is well spaced and the disc will not rub, even if it were to come untrue. The downside being that I have to depress the lever quite a bit before the brake engages. The brake does have good bite when it engages though.
My question is, assuming both brakes have to be similar when functioning normally: which one is wrong? Which brake do I have to bleed because the oil line has a problem? Should the pistons go back in more in the front? Should I be able to actuate my brake quicker in the back?
Thank you for your help!
I understand that the pictures I have here don't give you a perfect idea, let me know if more documentation would help.

To add to this: I’m going to be replacing this 140mm front disc (RT-MT900) for a 160mm RT-CL900 soon. I’m assuming the fact that I’ll put in a new (and hopefully true) disc + pads will help, but I’m still feeling like the pistons in the front are probably a bit too tight and there is probably air to let out in the line.
