Err, let me put it a different way. If your car has front and rear disc brakes (rear drum brakes are slightly different) now imagine there is no vacuum servo to help you press the pedal. You can’t ordinarily compress a fluid so the only play should be the small amount at the top of the pedal which is actually in the linkage between the clevis pin and the push rod. Apart from that (about half inch), the pedal will feel virtually solid and not travel. If you sit for a minute it should feel the same. If it travels further than it did before but comes back to the top after pumping I would suggest there is air in it and you could improve that by bleeding. Now remember that disc brakes are self adjusting and they sit with the pads in very close proximity to the disc. When you press the pedal, they hardly move before grabbing the disc (I think you call them rotors) and when you release them they don’t actually return to a stop like a drum brake, there is a little straightening up of the piston seal and the rotating discs clear a path. It’s a bit like tensing a muscle rather than physically moving the pads. With that in mind, you will feel that tiny amount of give in the four brakes under your foot when you press and if you take a wheel off you might see the flex pipes tense up so if you feel that slight give right at the top before coming solid then fine. If you’ve got strong legs, you’ll bend the pedal and the bracket slightly too. As long as it doesn’t travel further. To be honest, if it gets to that stage, don’t beat yourself up because it won’t make any difference. Try any new car in a showroom because they’re new and perfectly bled and they don’t get started so there is no chance of any vacuum assistance kidding you.
