I have a 2012 Maserati Granturismo s and I did a brake rotor and brake pad change with my friends. were all teenagers btw, front brake pads and brake rotors, were done quickly then we took the calipers off the back right rotor and realized we needed to get the electronic parking brake off and I went to do that forgetting the caliper was out. i pushed on the brake and the caliper came out with lots of brake fluid. we pushed it back in hopefully the correct way without any problems. we attempted to do a brake fluid change instead of changing it tho we put more in and built pressure to take the air bubbles out we did that like 3 times around the car in the correct order. but every time we try taking the parking brake off its been saying depress the brake pedal to take it off, meaning we still cant build pressure? i have no clue what to do now. Should i call someone?

Sounds like you got air in the system...Pretty hard to get it out without a scan tool to cycle the ABS modulator...Jason

What type of tool? and would one of those brake fluid changing tools be able to do it?

The caliper piston pushed out and now you have no brake pedal correct?

Yes I did manage to get the piston back in but air went in and lots of brake fluid came out, now no brake pedal

If you get air in one of these sometimes it won't I don't care how much bleeding you do...The air is trapped in the ABS modulator and you need a scan tool to activate the the valves...We have it happen when the brake filler bottle fell off while someone was eating lunch...Scan tool was the only way to get a good pedal again...Jason

Yeah that's what I'm thinking might call a mechanic
