Brake Improvements - Looking for thoughts

I replaced the speed bleeders with regular bleeders and hooked my MityVac to each caliper. I pulled a reservoir full of fluid through each one and got a ton of air out. It must have been trapped just right that regular bleeding wouldn't push it out. The pedal is mostly rock solid now with maybe a 1/2" of squishyness at the top so I'll probably bleed them again.

I did find a slightly kinked metal line at the left rear caliper which I will make a new one to replace. And the left front didn't flow a lot of fluid when bleeding, so I might unhook the caliper and flush the line out.

For now I am happy though, the brakes actually feel like they bite hard and I am able to lock up the front when I get on the brakes hard. In the 13 years I've owned this car, I've never been able to lock them up.

Between a replacement master from Dr Diff (to replace the couple year old one from Dr Diff that never seemed to work right) and PowerStop stop pads on all 4 corners, the braking improvement is huge!
