Anything special that I should know that is different with this brake setup . I have done my own brakes for years and have the skills but I have never done them on this vehicle. Do the calipers return with a clamp procedure or is there anything special about it ,screw in with special tool ? Any other things to know , tools etc.....?

there is a little piece of spring steel that act`s as a warning when your brake pad`s get low the pad does not look completly worn out take the tire off and double check them or take it to a mechanic you can trust to check them
You will probably not need anything other than a metric socket wrench set.
Many Toyota models have disc brake calipers that will flip up or down when you remove one of the two bolts that hold the calipers on. I am not sure of the setup on the Sienna.
When you remove either the upper or lower bolt and move the caliper, you can then remove the old pads. Also, you will need to push the piston(s) back into their cylinders to give you enough space to install the new pads. A large C clamp will usually suffice to push in the pistons.
I assume that you are talking about the front (disc) brakes. Some autos still have drum brakes on the rear, and those are a different story. They require several specialty tools to remove and replace the shoes.
CHANGING FRONT BRAKE PADS Jack up the car.Take off your tire.Find the bolt on the back of the caliper and take it off.This should release the caliper, pull the caliper off the disc.Now you should be able to take the pad out.Replace the pad.You'll need a special tool to reset the caliper. As the brakes wear down, the caliper gets tighter so the brakes still work. I'm not sure exactly what its called, but you can borrow one from auto zone. Follow the instructions that come with it to reset the caliper.Slide the caliper back over the disc. If it doesn't go on, you need to reset the caliper more.Put the relese bolt back in.Put your tire back on.Drive slowly and test the brakes. CHANGING THE REAR BRAKE PADS The rear brakes on the rx8 are a bit different than most setups...be careful! The only way to move the piston back into the caliper is by way of a special allen head bolt that is directly behind the piston, on the back side of the caliper, installed under a 14mm bolt. You have to remove this bolt to gain access to the allen head. As you loosen the allen head bolt(counter-clockwise), the piston will move back into the caliper. Installation is pretty typical, again, the allen head bolt being the unusual part. The manual says to tighten this bolt until the pads contact the rotor, then loosen the bolt 1/3rd of a turn, then reinstall the 14mm bolt.
it is a torx bit for your caliper bolt.a size t50 if I am thinking right. use a good one as these can be hard to get broke loose.as far as rotors remove cliper slide bracket with an 18mm two bolts and rotor will slip off. might have to tap with a hammer
Ford taurus's have the same setup on the rear calipers and it requires a special tool or persistance on your part with a pair of channels lock pliers and a c clamp. turn the piston clockwise as you press it in with a c clamp or get the tool mentioned below.
Harbor Freight has this special tool... found HERE
And yes, once you get the piston in it will come back out on it's own and yes will automatically readjust.
Not really anything special, just if you have rear disc brakes there is a special tool you need to push (rotate) the caliper piston in because of the fact they are special calipers equipped for parking brake function.
