Rear Brake Disc/Parking Adjustment Options

[trdproven]

Are there any adjustments that need to be made if you put on a new caliper I noticed these celicas use a duo servo mechanical drum parking brake design, where the cable goes into from behind the rotor vice externally. is the only rear parking brake adjustment in the center glove only? I keep reading you adjust something in the rotor first and then move on to the adjustment in the center glove. is that an adjustment in the rotor where that rubber plug is? I noticed when I looked into the rubber plug, its not very clear what to adjust there, the toyota service manual is not very detailed. it says to adjust something so that pads basically lock the rotor, the description sounds like drum brakes but it was listed under disc brakes and drum brake shoes had its only paragraph. Just wondering if anyone knew. I'm used to the hondas rear brake set up.

This what the manual says:
Disc Brakes
Raise and support rear of vehicle. Remove rear wheel. Release
parking brake. Remove adjustment hole plug from rear rotor. Turn
adjuster until parking brake shoes lock rotor. Back off adjuster 8
notches.

So again, i just changed my rear brake calipers.

#1. I noticed if I grab my wheel with handbrakes on, my car can move about an inch back and forth before the hand brakes lock the wheel, is that normal? It’s the same thing when I tighten the wheels with a breaker bar it moves about an inch then locks allowing me to tighten my lugnuts. Isn't it supposed to be tight from the beginning meaning already the wheel does not spin? In other cars, they are already locked so can't say for sure whats normal.

#2. Also when I have the car lifted, with handbrakes not on (released), I can spin the tire each about a good spin 10 times, is that normal drag for brakes? Should it be less spins? I noticed it being less on other cars when I try to get ideas but comparing.

#3. I also noticed that the drag sound from the pads sounds a bit inconsistent on the right side from the left side, the left side sounds more like consistent drag which should be the normal one. The right side seems like a skipping dragging sound, not a constant whooshing sound.

#4. Is there some type of adjustment inside the rotor? I noticed there is a rubber plug that when you remove, there is a hole to see inside the rotor. But I do not see anything to adjust. Toyota manual says the emergency brake is duo-servo, not sure what that means, but the cable runs to just behind the rotor, the manual says to adjust something but I don't see anything in there. For the handbrake when I pull up according to the manual says it should be between 4-7 click when you pull up, that’s about what I get, so I guess that adjustment is still ok. So I am still not sure if I still need to adjust anything inside the rotor.

Just wanted to see if anyone had some ideas just so i can try out from your experiences and if anything make my problem solved faster. If not, I usually troubleshoot here and there when I have time and they get solved anyway over time, but I appreciate any extra info.
