I planned on changing my pads yesterday. That went very smoothly, except for the fact that I accidentally loosened the caliper bolt and that cost me for the rebuilt caliper (hard to find on a sunday at 3pm). I installed the new caliper ensuring to bleed after installation.
Problem is that the pedal is really spongy and my brake warning light (red) is on. Plenty of fluid in the master cylinder reservoir also. I drove it on a safe empty street and still the same feeling after many stopping attempts. Checked fluid and it was still at the same level.
I will have to check the rear shoes today as I just read it should be done and adjusted as necessary.
Any advice on the brake operation and the warning light?
I don't get why loosening the bolt required replacing it. But your problem is you still have air in the system. Depending on how much fluid you lost, and how much air got in, you may have to bleed the other 2 or 3 wheels.
The level is not going down because you are not losing fluid
The reason I replaced it was because the seal was compromised when i loosened the bolt on the caliper. I could not get it to seal back up after tightening it back up... so that was a $115 mistake.
I figured i would have to bleed it again... but would all the lines be necessary?
The air causes an imbalance in pressure so you will get the light. On some vehicles, I can get away with bleeding one wheel, on others it is more. If your master cylinder went dry, you'll have to do the whole vehicle
2006 Tundra V-8 double cab with 31k. I checked the master cylinder float. Of course it was stuck... So that took away my light issue. I will bleed all four wheels. Might as well since it does stop the truck and all. I have to check the rear shoes also.
I also have had my ABS light on for a few weeks. I understand my warranty covers this and I haven't messed with it. Anything i can look for while i am already in there?
If you're in the drums, might as well service the parking brake. There's a beautiful DIY sticky post on this at the top of the Brake forum. Looks pretty easy.

If you let the master run low, air may now be trapped in it. Bleed the master by loosing the lines and letting the fluid escape just as you would when bleeding through a bleeder screw. After doing this bleed again at the wheels and I bet you problem is solved
