DIY brake job - dash lights and battery

I have some questions regarding a few things on my DIY brake job. I've seen some similar discussionsbut none quiet as specific on my 2008 toyota prius. I've successfully changed one of the front rotors and brake pads however two things are giving me issues. First is the ABS and VSC dash lights are on now, and I did not disconnect the 12volt battery before changing the parts out. Yikes I know now! Will I cause further issue if I disconnect the 12v battery now before changing the other front pads and rotors? Or is it okay to do so? I also bled the brake valve before pushing the piston in- and am not sure if that's okay for a prius? Last question is I have tried testing the brake pad just driving a tiny bit and it feels like a wobbly braking - where it causes the car to shift side to side a little bit when pressing the brake. Could that be the wheel or the rotor isn't straight? And or lugnuts are torqued correctly? Any advice would be awesome.

 

Thanks so much for your response. I don't have a scan tool, and can't seem to find more info on how to use the jumper wire between the Tc and CG method like you mention. Could you direct me where I should look for more details on the TC and CG method to get the trouble codes?

 

here are the blink codes that showed up- let me know what you think for next steps?


ABS

3-1

3-2


VSC

4-5

4-3


Brake system warning light

6-2

3-6


Tire pressure exclamation point with ridges under sign

2-3


Airbag symbol

Blinking constantly during the blinking though it doesn’t light up when the car is just turned on/sitting in parking without the pin in the Tc CG ports

 

Thanks so much! I'll see what else I can find and really appreciate all your help, with insights and info.
