I got a 92 ex first off right now im changing the rotors and pads in the back now and i cant get the caliper piston to push back in. when i did the front end, they went back in no problem. any ideas??
also, i got a leak in my trunk. i had two but i found one that was leaking through the sun roof drain on the passenger side. but now there water coming in from the top of my trunk allmost directly below my rear window. i also had my window replaced not to long ago...could of it been because of a bad instalation on my window?? i can also take a pic from where its coming from if needed

 

also i have taken the trunk seal off and siliconed it all the away around so i know thats not leaking

 

 

the rear caliper pistons need to turn to go back in.
The trunk leak could be the seals behind the tail lights, try using some silicone around them. You will find they are held on by studs, and an 8mm deepwell socket is handy to have for getting the tail lights loose.
