Need advice. I am replacing brake rotors and pads for all four wheels. My home 2-car garage only gives me enough room to work on the side facing the other car, the middle of the garage. Is it safe to install the rotors and pads on both the front and rear passenger wheels first - then back the car out of the garage and pull it back in on the other side so that the driver side gets the room to work? Any problem doing one side and then the other instead of both front and then both rear?
I'm going to assume you have a very good reason for not taking the other car out of the garage to give yourself more room...
People replace either the front or rear brakes together because they are "on the same axle" and replacing one side doesn't make sense because both sides should wear at the same rate. Replacing one side could make the car pull to one side or other strange behavior.
That said, I don't see any reason you can't change one side immediately before changing the other side. I wouldn't drive very much like that because how the brakes might react is hard to predict, but if you're literally just backing out and then back in - go for it.
Before backing up, make sure that the brakes have pressure. I'd hate for you to introduce air into the lines then try to back up and keep going because the brakes don't work!
I found two videos that may help to move the car into a better position to work with.
This should help with your workspace problem.
One video uses Gojaks and the other system uses something similar to furniture coasters.
Gojaks are useful for moving cars in and out tight spaces.

If your garage is large enough perhaps in the future you can use a system like the one in this video below. It's a car lift that places cars up towards a ceiling. Some are single lifts I think this one has two separate lifts.

If you are just going to move the car to get into a better position to work on then this is fine.
One important thing to be aware of though is that if you have done anything which might allow air into the braking system eg disconnecting pistons or any other part of the brake hydraulics then the hydraulic brakes may not work at all well until you bleed them. So take great care and don't perform any maneuvers which require sharp braking and test that the handbrake/emergency brake works well beforehand and be ready to use it.
