Try taking the brake MC reservoir cap off next time to relieve the pressure.

 

I dont like forcing the fluid back through the mc...dont ask why
I dont care about squeezing out a bit of fluid.

 

you dont need to remove the entire caliper.

 

I always clean them(the brake calipers) with brake parts cleaner and then skeet some silicon spray into the caliper seal while it's apart. You don't have to, but i like doing my stuff perfect, which is what you don't get most of the time if you pay somebody. I also rub that break lube stuff onto the back of the pads. If they don't come with the pads, ask for it. Some calipers press back in, and i've done some that turn back in, with a big flat headed screwdriver type tool. I've always left the old pad on it to press it back in with a c-clamp so you don't mess up your new pad. Also, take the resivor cap off. Some fluid may overflow out when you press them back in. Don't forget to replace the cap when finished. It's basically a very easy job. Doing brake shoes is a little more ticky, but still doable if you have some mechanical ability and the tools. Cheaper to go buy the tools you need instead of paying somebody. You will then have the tools for later in life when you need them again. I don't think i've ever paid anybody to do anything to any of my cars my whole life. Except when i was still in high school, when i did not have all the tools or knowledge.
