here i am again, i cant seem to find the way to remove to calipars. it's not like the front calipars, set up is diferent. can someone pls let me know what im missing.

It is very similar to the front. I losen the park brake cable (where it bolts to the rear axle mounts), remove the park brake cable OR the whole park brake mechanism from the caliper then undo the two bolts on the caliper itself.

When you put them back in (I assume you are doing a pad change), the pistons wind back in instead of pushing.

is that the bolts with the seals between them and the calipar? cause the front has those but there are 2 other bolts that tighten on the fronts
