Hi so i just finished replacing my front passenger side caliper along with pads and new rotor as the caliper turned out to be seized :/ . Also the the driver side was replaced just the rotor and pads no caliper. I started the car up and my brake pedal was spongy!! And it has some pressure but its not firm like it used to be. What can i do should i rebleed the whole system? If someone could please enlighten me thank you!
