Keep in mind just for knowledge of years of changing brakes 90% of Pistons that have holes in the middle there a hollow you can put the C clamp on the ones that are flat in the front are threaded good video didn't know that my Chevy volt was like that now I know when I change the brakes
Just what I was wanting to find out for my Ampera over here in Scotland. I'm used to this rotating of the piston to get it to retract and you can buy a piston wind back tool which makes it a lot easier than a pair of needle nosed pliers. Thanks.
Thanks! I'm glad I found your video. It's the same on the 2nd Gen Volts. I found your video and mine are similar. I would add that, I use channel lock pliers until they were half way back in and I started to feel a different resistance. At that point, you can use the C-clamp to compress it the rest of the way
Im glad im not the only one to be outsmarted by this style of caliper. Years ago I did my wifes rear disks on her G6 and ran into this. After a long list of profanity I ran a google search and the caliper pistons screw back in. Man was I pissed lol, combine that with whoever had last taken the wheels off WAY over torqued the lug nuts to the point that I broke 2 ratchets and had to get a breaker bar.
I had this problem too. I used a bearing puller and a tool I made out of steel rod with a center drilled on one end to mate with the bearing puller's screw. I put pressure on the cylinder with the bearing puller pushing through the steel rod, and used one of those knipex cobra pliers to twist the tool which rotated the brake cylinder like a clutch, allowing it to compress. I think only the rear brakes make you do this song and dance, though.
You are correct that the rear only does this crazyness. it took me hours to figure this out. i figured someone else may have the same issue and could save them some time.
As the rear brake pads wear, the caliper piston gradually rotates and comes out, and is not allowed to significantly retract. This design is for the rear parking brakes which are operated by a motor and cables and only have a fixed amount of travel to engage.
First saw this on a Ford Five Hundred. Other vehicles are using that same style of caliper. You can borrow the tool from Autozone or buy the kit off Amazon for $25. It is WAY easier than using the pliers as shown. Good video.
This guy has cross drilled and slotted rotors on a Chevy Volt!🤔🤓. Now I suddenly feel my Chevy Volt has inadequate brakes😬. Well better start saving for mine. Like if you agree🤓🤓
