checked the pads and caliper on one side and this is what i found, seems to me the caliper's pistons are out awful far. anyone else think so? truck is pulling to the left after i did the upper control arms on both sides. seemed to stop after a hard brake but came back later.

 

The pistons look ok. But the outer pad looks just a little thinner than the inner pad. It could just be the camera angle but if the outer pad is thinner I would look at the hardware before condemning the caliper.

 

i greased the sliding pin thing real good when i put it back together, it was so tight getting the caliper back on i couldnt get one of the little metal shim things back on...

 

Did you try compressing the caliper?

 

no i didnt. i hadnt recalled having to do that before when just removing the caliper with good shape pads.

 

You don't "have" to do it but it will make putting the caliper back over the pads easier and it will let you know if the caliper is sticking if you can't compress the caliper.

 

ok will have to do next time i take it apart.

 

What kind of grease did you use on the slide pins? Regular bearing grease won't work, you have to use dielectric grease.
