Default Rear caliper bolt and oil drain plug

I was replacing my rear rotors and pads and saw that the 8mm hex carrier bolts was pretty rusted and stripped. I'm looking for replacements online and only saw ESC selling them as a kit for both front and back. I've checked all the other sites on the sticky and cant seem to find them maybe im calling them a different name? Also did anyone get away with just using needlenose pliers for retracting the piston back in? I bought the cube from harbor freight and it was too small. For the oil drain plug I read somewhere on here the size was 24x1.5 and that i could get a magnet one from autozone for 4 bucks. i went there today and they had 2 magnet ones for 4 bucks and none of them were 24x1.5.. one was M12 - 1.75 x 15 mm. head x 34.55 mm. and the other was 1/2 in. - 20 x 3/4 in. head x .898 in. which one is it?

Yes. The brake caliper retractor tool from harbor freight makes it easier though. Even though it wouldnt fit perfect, it made it easier to turn the piston.

The tool that I got was a cube that was "universal" you pretty much put it on a 3/8 ratchet but the cube did not line up with the piston nor was it big enough to reach both gaps

Yeah try one of these kits if the needle nose dont work. http://www.harborfreight.com/18-piec...kit-97143.html

I would turn the piston with the needle nose, then press with a c-clamp, and swap back and forth till it was in.

if you're going back to autozone anytime soon, they rent a caliper tool for ~$50... you get your money back when you return the tool...

Yeah that cube is a piece of ****. Rent the good one, its more than worth parting with $50 for a few hours. As for those 8mm carrier bolts, if you don't want to buy the kit you could replace the cap screws with real actual bolts. That obviously requires that you get one out intact and have another car to drive to the hardware store though lol

Did you already do your front brakes?

EDIT: try this.

Thanks for the replys

I recently changed my front brakes last week, I'll prob just rent that tool to make life easier. As for the bolt i'll try and keep an eye out for it at the hardware store. Also any word on the size for the oil drain plug? I keep seeing 14x1.5 or 26x1.5 I had a long talk with one of the people at autozone. They said that the standard size was 26 ive been looking around the forums and they said 14

I just use a C-Clamp and one of the old brake pads to push the piston in. Works everytime.

Do NOT do this. The rear caliper pistons have to be turned while they're being compressed, otherwise you'll blow the piston seals.
