I have just changed my 2009 pontiac vibe - 2.4 L , front wheel drive -rear disk brakes ...
Here are some tips...
For all the youtube videos that show a push in caliper piston, this car has a WIND back caliper... AND - for those that have watched
videos that say you can do this without the wind back tool... Fa Ge Bout It.... you should get the wind back tool on amazon

You will need to use the RIGHT handed tool with the four tip dices in the upper right hand corner....Lubricate the threads on the tool B4 using...
Use the caliper grease you bought....
B4 you start winding the piston back in, CLEAN the piston bushing and head and coat the bushing with grease... Coat the tipoff a flat head screw driver with caliber grease and coat the bushing in between the bushing and piston... This will help the bushing from BINDING on the piston and ripping when winding back....
Dont do ANYTHING else B4 you wind the piston back... If you can't get the piston back you will NOT be able to put on NEW pads... Don't remove old brakes or anything B4 you compress the piston.
Winding back the piston- FIRST Break open the bleeder valve... and connect you brake fluid capture device... The valve should be OPEN...
Mount the wind back tool. As you screw in the piston (clock wise) you should see brake fluid enter your capture device tube... This is a good sign...
There are TWO parts to the wind back tool ( actually more) but when you wind the shaft of the tool in, the shaft may be under a lot of pressure... This will be a problem when you try to remove the tool....DO NOT unwind (counter clock wise) the tool... The BASE of the tool can be used to dismount the wind back tool... as you may NOT be able to unwind the piston to release the tool... get a crescent wrench and screw the BASE IN clockwise... this will loosen the tool to remove it....
Once the caliper has been pushed it enough, you can start replacing all brake parts....
NOTE= There are two different CALIPER clips on each brake.... They may look the same but the bigger of the two is on the BOTTOM of the caliper....
Make sure you replace the CORRECT clip in the right place...
I ordered ceramic brake pads from NAPA... They don't fit... If you order from napa GET the rear brake PREMIUM kit.... that comes with the correct pads and caliper clips... The INNER pad has a screech arm on the pad... If your new pads so not have this you have the wrong pads....
There are NO PAD CLIPS on the rear brake PADS.... PAD CLIPS... NOT CALPER CLIPS....
