Need Help: Major Brake Issues
Did my brakes myself as I've done tons of times with past cars.
Changed the front rotors and pads but didn't have time to bleed the brakes. It drove fine but a little squishy. Got around to doing the rear rotors and pads this morning (a day later) and bled the system. Now every light (vsc, brake, abs, etc) is on and I have little to no brake pressure. Fluid is all there.
Any ideas?

Well one thing I didn't mention was it was my first experience pushing caliper pistons back in where the caliper had opposing pistons. so when I was clamping down one side, one of the pistons fell out so I figured I had to bleed the system since air must have gotten in then.
So what's the trick with the key? I called a tech friend and he said you need a scan tool to activate the brake booster motor but didn't mention anything about being able to use the key in lieu of having a scanner.
once the brake motor is activated, does that mean I don't have to have any pumping and holding the brake pedal?
It did strike me odd that when I was bleeding out the brakes the fluid just kept coming and I did hear what sounded like a motor kicking on. But I don't recall having pushed the start button at all.
Thanks for the feedback. If anyone knows what the trick is, I'd greatly appreciate the insight.

Thanks to all for the feedback.
I read that thread you linked but it sounded like warning lights was his major issue, for me my brakes don't bite. The car hardly stays still once I put it in Drive while holding down the pedal. And when I stomp on the pedal while moving it'll slow-slowly and eventually lock up one of the front tires. I know I bled the system through though.
What a mess. My local mechanic has all the scan tools and said he'd be able to reset the computer and re-flush if necessary. I'll keep my fingers crossed.
Thanks again for the info.

wow, that doesn't sound good... seems like the whole system is not functioning and not applying pressure for you when you bleed the system.
just curious, was your car running when you bleed the system? i wonder if that helps make a difference. not to take out the lights, but at least to get the brakes on

I am always fascinated at how people pay so much a car then try to service it themselves. I wish you the best but this is probably going to cost you some time and a bit more money. Good luck

Unfortunately newer cars with all the electronic nannies are becoming harder for hobbyist to work on. Guess I'll only do brakes on my geriatric '85 Corolla going forward.
Again, live and learn. But I appreciate everyones' constructive and encouraging responses.
