how do i get that on the piston

 

First of all your pic is of the front axle. On the rears they are different then the fronts. 99-00 Si rear disc setup shown


Now looking at the correct pic, what exactly is it that you need/want to know?

#1 is the rebuild kit

ok first off: why rebuild? it's essentially cheaper to just replace.

second: why rebuild and put the liability on you when you can replace it and use the liability of the manufacturer to your advantage when something is wrong.

and if you are going to rebuild it, and what to know how to push the piston back in:

well since it's all apart (i'm assuming), remove the square cut seal (piston seal) with a wooden or plastic tool, it's a black rubber ring inside the bore. and clean out the whole bore with brake cleaner (denatured alcohol). then put the square cut seal on (be sure it's on properly or you wont be able to seal in pressure, then put the piston in. if it doesn't go in, then it's at an angle. the piston has to sit dead center, and u kind of use moderate pressure until it lines up with the square cut seal.

but in the end ur better of replacing instead of overhauling, trust me.

oh and by the way, the arrow is pointing at the dust boot i believe, not a piston. to put that on, just pull it over the grooves and it'll will fit snug.

 

looks pretty complicated
